CSS Float Theory: Things You Should Know


The concept of floats is probably one of the most unintuitive concepts in CSS. Floats are often misunderstood and blamed for floating all the context around it, causing readability and usability problems. However, the reason for these problems isn’t the theory itself, but the way the theory is interpreted – by developers and browsers.

Still, if you take a closer look at the float theory, you’ll find out out that it isn’t that complex as it appears to be. Most related problems are caused by the older versions of (take a guess) Internet Explorer. If you know the bugs, you can control the way information is presented in a more sophisticated, profound way.

Let’s try to tackle the issue and clarify some usual misunderstandings, which always appear once floats are being used. We’ve browsed through dozens of related articles and selected the most important things you should keep in mind developing css-based layouts with floats.

What You Should Know About Floats

  • “The practice of flowing text around an image goes back a long, long time. That’s why the ability was added to the Web starting with Netscape 1.1, and why CSS makes it possible using the property float. The term “float” refers to the way in which an element floats to one side and down, as described in the original “Additions to HTML 2.0″ document that accompanied the release of Netscape 1.1.”

  • “A floated box is positioned within the normal flow, then taken out of the flow and shifted to the left or right as far as possible. Content may flow along the side of a float. […] When a box is taken out of normal flow, all content that is still within normal flow will ignore it completely and not make space for it.” [Float Positioning3]
  • “When you float an element it becomes a block box. This box can then be shifted to the left or right on the current line. The markup options are float: left, float: right or float: none.” [Floatutorial: Float Basics151154]
  • “You should always set a width on floated items (except if applied directly to an image – which has implicit width). If no width is set, the results can be unpredictable.” [Floatutorial: Float Basics151154]
  • “For one, the box being floated should have a width defined for it, either explicitly or implicitly. Otherwise, it will fill its containing block horizontally, just like non-floated content, leaving no room for other content to flow around it. Second, unlike boxes in the normal flow, the vertical margins of a floated box are not collapsed with the margins of boxes either above or below it. Finally, a floated box can overlap block-level boxes adjacent to it in the normal flow.”
    CSS Positioning: Floats6

  • “The first thing we need to remember is that a floating element is shifted either to the left or to the right. It is not possible to make an element float in the centre, something that often is frustrating for beginners. The basic rule is that a floating element is only shifted sideways.” [Float Layouts4818171698]
  • “When we float an element it is shifted to the right or to the left until it reaches the edge of the containing block. If we then float another element nearby in the same direction, it will be shifted until its edge reaches the edge of the first floating element. […] If we float more elements in the same direction they will stack up, but sooner or later we’ll run out of space […] when there is insufficient space on the line, they are shifted downward until they fit.” [Float Layouts4818171698]
  • Containing blocks or containing boxes: “A containing block is a box or block that contains other elements (descendant boxes). An element’s containing block means “the containing block in which the element lives”. [Floatutorial10]
  • “Floated boxes will move to the left or right until their outer edge touches the containing block edge or the outer edge of another float.” [Floatutorial: Float Basics151154]
  • “When specified, the box is positioned vertically as it would be within the normal flow, its top aligned with the top of the current line box. But horizontally, it is shifted as far to the right or left of its containing block as possible, within that block’s padding (just like other content). Surrounding inline content is then allowed to flow around the opposite side.” [CSS Positioning: Floats12]
  • “Since a float is not in the flow, non-positioned block boxes created before and after the float box flow vertically as if the float didn’t exist. However, line boxes created next to the float are shortened to make room for the floated box. Any content in the current line before a floated box is reflowed in the first available line on the other side of the float.”
    W3C Visual Formatting Model13
    W3C Visual Formatting Model14
  • “If there isn’t enough horizontal room on the current line for the floated box, it will move downward, line by line, until a line has room for it.” [Floatutorial: Float Basics151154]
  • “A floating box can never end up above the upper edge of the line where it’s created. […] The upper edge of a floating box is aligned with the upper edge of the current line box (or with the bottom edge of the previous block box, if there is no line box).” [Float Layouts4818171698]
  • “In order to really understand float theory you have to understand what a line box means in CSS. Unfortunately, that in turn requires you to understand what is meant by an inline box. […] An inline box is generated by those elements that aren’t block-level, such as EM. […] A line box is an imaginary rectangle that contains all the inline boxes that make up a line in the containing block-level element. It is (at least) as tall as its tallest line box.” [Float Layouts4818171698]
  • “If we enclose each column in a DIV element with float: left they will appear side by side, just as we expect columns to do. If we then want a full-width footer to be shown at the bottom, no matter which column happens to be longest, we only need to set clear: both on it.” [Float Layouts4818171698]
  • “The potential drawback to using floats to contain floats is that you rely on browsers to consistently interpret the layout of multiple nested floated elements. The situation becomes more fragile if these floats are part of a more complicated layout, one possibly using floats, positioning, or tables.” [Containing Floats192]

Clearing the floats

  • “Elements following a floated element will wrap around the floated element. If you do not want this to occur, you can apply the “clear” property to these following elements. The four options are clear: left, clear: right, clear: both or clear: none.” [Floats and “clear”20]
  • How to clear CSS floats without extra markup – different techniques explained. There are three major approaches: a) Floating the containing element as well, b) Using overflow: hidden on the container, c) Generating content using the :after CSS pseudo-class. A test-page for techniques21. [How to clear CSS floats without extra markup22]
  • “The standard method of making an outer container appear to “enclose” a nested float is to place a complete “cleared” element last in the container, which has the effect of ‘dragging’ the lower edge of the containing box lower than the float.”
  1. <div> <!-- float container -->
  2. <div style="float:left; width:30%;"><p>Some content</p></div>
  3. <p>Text not inside the float</p>
  4. <div style="clear:both;"></div>
  5. </div>
  • [How To Clear Floats Without Structural Markup312723]
  • “A common problem with float-based layouts is that the floats’ container doesn’t want to stretch up to accomodate the floats. If you want to add, say, a border around all floats (ie. a border around the container) you’ll have to command the browsers somehow to stretch up the container all the way. You can clear the floats using overflow method24.”
    Clearing Floats25
    Clearing floats26
  • Using :after: imagine that we use :after to insert a simple character like a ‘period’, and then give that generated element {clear: both;}. That’s all you really need to do the job, but no one wants a line space messing up the end of their clean container box, so we also use {height: 0;} and {visibility: hidden;} to keep our period from showing.
  1. .clearfix:after {
  2. content: ".";
  3. display: block;
  4. height: 0;
  5. clear: both;
  6. visibility: hidden;
  7. }
  • [How To Clear Floats Without Structural Markup312723]
  • Clearfix: “When a float is contained within a container box that has a visible border or background, that float does not automatically force the container’s bottom edge down as the float is made taller. Instead the float is ignored by the container and will hang down out of the container bottom like a flag. […] IE/Win does enclose a float within a container ‘automatically’, but only if the container element has a stated dimension.” [Easyclearing: How To Clear Floats Without Structural Markup28]

CSS Float Bugs

  • When […] container element has links inside, following the float. When this happens and certain links are hovered, the auto-enclosing behavior is toggled or “switched off”, causing the lower edge of the container box to suddenly jump up to the bottom of the non-floated content. Hovering other links restores the behavior. This interesting effect is of course called the IE/Win Guillotine Bug29. The toggling only occurs when a:hover is used to change the link background or many other styling changes, such as padding, margin, or any font styling on the link. Strangely, having the text color change on hover does not toggle the bug.
    IE/Win Guillotine Bug30

    [How To Clear Floats Without Structural Markup312723]

  • The IE Escaping Floats Bug32: “If you use a div box with margins, borders and a number of left floated divs, you’ll get two display errors in IE Win. One, the container is only containing the last line of floats , and the floats are also running off to the right, all the way to the right screen edge. also causes a horizontal scrollbar at many screen sizes. […] Solution: a height can be given to IE/win and not affect the displayed height of the container. This is possible because IE has another non-standard behavior concerning boxes and dimensions.” Holly Hack: assigning a height to the element, i.e. height: 1%;.
    IE Escaping Floats Bug33
  • The Win/IE6 Peekaboo bug34: “A liquid box has a float inside, and content that appears along side that float. In IE6 the content disappears. When you scroll down, or perhaps switch to another window, upon returning back there it all is (this long standing bug has been suppressed in IE7).
    Win/IE6 Peekaboo bug35
  • “IE/Win gives a left floated block a right margin of 3px. No matter what you do, the margin is still there. To see this in action, check the floating bug36 first and then the double float fix37.” This bug is also called The IE Three Pixel Text-Jog38 [Floating Bugs39].
  • IE Duplicate Character Bug4340: “Internet Explorer 6 has a puzzling bug involving multiple floated elements; text characters from the last of the floated elements are sometimes duplicated below the last float. The direct cause is nothing more than ordinary HTML comments, such as, <!-- end left column -->, sandwiched between floats that come in sequence. Bugfix41.
    IE Duplicate Character Bug42

    [IE Duplicate Character Bug4340]

  • “One of the most common tasks when laying out the content of a web page is floating images to the right or left so that text flows around them. The addition of the clear to the floated image ensures that each one will always sit below the previous one. However, placing the float and clear properties on the same element can cause large gaps to appear in Internet Explorer (IE) — gaps that take more complicated CSS to fix than what we’ve used so far. Bugfix44.” [Close Gaps Next to Floated Images in Internet Explorer45]
  • “You place a left float into a container box, and use a left margin on the float to push it away from the left side of the container. In Internet Explorer the left float margin has been doubled in length!” [The IE Doubled Float-Margin Bug46]
  • “The bug demonstrated here causes in-line elements (images, text) adjacent to a floated div to appear to be indented from their expected location. The indentation is caused by IE/Win’s weird handling of margins on floated elements.” [Floats, Margins and IE47]
  • “There is a simple solution that fixes many of the IE float bugs. All floats become a block box; the standard says that the display property is to be ignored for floats, unless it’s specified as none. If we set display:inline for a floating element, some of the IE/Win bugs disappears as if by magic. IE/Win doesn’t make the element into an inline box, but many of the bugs are fixed.” [Float Layouts4818171698]
  • “Using a combination of float and negative margins on an element makes any links in the element unclickable in Safari 1.3 and Safari 2.0. Text also becomes very difficult to select, and if you tab through the links they disappear when they lose focus. A workaround is to add position:relative to the CSS declaration for any floated elements with negative margins.” [Float + negative margin problems in Safari49]
  • “MSIE 7 now correctly implements the W3C specification by collapsing containers that include floated children. However, as it has not implemented generated content, the so called easy clearing method50 is not an option for clearing floats in MSIE 7. The overflow method is an appropriate solution for all versions of Internet Explorer:
#content { overflow : hidden; _height : 1%; }

    This article provides a brief introduction to these floated elements, explaining the CSS float and clear directives and providing some examples of how you can use them to better position HTML elements on a Web page.
  • Create Columns with Floats58
    In general, there are currently two ways to create a multi-column layout in CSS: absolute positioning or floating. The vast majority of the time, floating will be your method of choice in laying out your web pages with CSS. In this tutorial, you’ll learn how to create the look of columns using the float, width and margin properties.
  • Safe Lists Next to Left-Floated Elements
    There are lots of different methods to format nice html lists. But are those methods reliable in all contexts and in all browsers? In this article, we’ll have a look at a simple context: a list with some left-floated element next to it.
  • Creating Liquid Layouts with Negative Margins [and Floats]59

    It’s time to think outside the box, or maybe, more accurately, floating alongside of it. Where did we lose our collective CSS coding creativity? CSS allows so much freedom from traditional table based layouts that we sometimes do not consider page and layout design alternatives. What a pity. Time to think outside the box!

    I’ve been coding with floats for a couple of years and have never used “clear” in the code. I haven’t seen a good reason to actually use this based on the way i build sites. It appears that if you make sure your width fits within your container divs and remember where everything is going to be wrapping you’re good to go.

    Could anyone explain why you would actually need to clear your float? showing an example of a non cleared and a cleared examples?


  2. 52

    One to keep. A nice comprehension of the float soup. Still IE will break it somewhere down the road for you; at least that’s my experience. On a side note: why are we still waiting for a vertical align possibility in CSS?

    In ie6 it is not showing content under footer.

    No mention of liquid images to scale content dimensions?

  10. 460

    kindly use your imagination to interpret the following round brackets – this blog comment tool appears to remove code inside html brackets

    baking accessible floats for thumbs

    The focus of this comment would would be LIQUID images.

    Floating a liquid image into the margin makes zooming fun and information accessible. Nice thing about liquid image dimensions is they fit almost any device, and are easily avoided by print machines, teletypers and similar machines. Floating liquidity can also dress-up inline elements, leaving extra room for creative tweaks.

    .floatcenter{margin:1em auto;width:70%;}

    (blockquote class=”floatcenter”)
    (img alt=”” class=”imgthumb” height=”10%” width=”10%” src=”image.png” /)
    Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Praesent aliquam, justo convallis luctus rutrum, erat nulla fermentum diam, at nonummy quam ante ac quam.

    Why this works is because the same extra top secret patents browsers use to build their box models around screen center are not crimped for media the way they are for that glaring “float:center” [oops] ommision.
    In the now dead original xhtml2.1 draft the manufacturers even tried to kill this inline image gem too. To be kind, we should consider the entirely boxed liquid image.

    But that is for another Smashing article.

  11. 511

    This statement is not accurate:
    “For one, the box being floated should have a width defined for it, either explicitly or implicitly. Otherwise, it will fill its containing block horizontally,”

    Floating a box is often the ONLY way to get it to shrink wrap it’s content, NOT expand to fill it’s containing block horizontally. You have described the opposite of the actual behavoir here.

  12. 562

    excellent article

  13. 613

    One possible way to “shrink wrap” your content would be to use width: auto;. But, as with many CSS selectors and attributes, your mileage may vary based on browser make and model. ;)

  14. 664

    The quote about not being able to center with float is so true! I found it so frustrating when I first started.

  15. 715

    I have been researching issues with IE7 only, which is strange – the flow operates in all browsers including IE8.

    A containing block is floated and has multiple tiers of nested elements, some of which contain floated elements themselves.

    The container has a fixed width, the two child containers are floated and also have fixed widths.

    The total sum of the two child containers is double that of the parent. Using overflow, the children are floated left and the last block in the order is hidden from view (similar to a mask in Flash.

    This works in all browsers except IE7, where the last block on the order is shown floated next to the first block, but appears broken outside of the parent (i.e with borders on, the border does not wrap both elements).

    No idea how to resolve it but I think that it is to do with a large quantity of nested floats.

    I like to add the clear float solution to nearly all block level elements except for the footer and p element. It can mess up the vertical margins as elements don’t collapse correctly, but if you using padding instead, it works really well. I wrote an article on it.

    I’m sorry but I just read some 8 sentences (I guess, some 3 paragraphs) then scrolled directly to the bottom to view the comments.

    May I argue about setting every floated element with a width, I mean, giving a width for every floated element is unnecessary, as long as you clear the following tag or element which is next to it that you don’t want to float with it, something like …

    #search {
    float: right;

    #content {
    clear: right;

    Unless you will explicitly use “position: relative” to place it beside (or along) the floated element, that’s the only case I see where giving widths for the floated one will be necessary; otherwise, it’s only wasting the file size.

    The tricks are also helpful but remember that tricks should only be the last resort; they are non-essential if you have used the floats properly in the first place.

    Oh my goodness!!! This is such a lifesaver for a web developer. I am able to keep clean, semantic and valid code with its help. Darn IE … I ought to choke the life … uhmm yeah

    I’m getting through this amzing tutorial but the links “floatelayouts” at the top (http://www.autisticcuckoo.net/archive.php?id=2004/12/10/floating) don’t work. Could you fix, please?

    I’m using WordPress. I’m using a two column format (left is main content, right is narrow sidebar). The sidebar is set to a specific width, with float:right. However, if I set the left column to a specific width, then (of course) the main content will not expand to the full width of the page — when there be no content in the sidebar. But, I’d like for the main content to fill the page when the sidebar is not being used on that page.

    I’m using the following style, and it appears to work. But, I’m wondering if it’s unreliable and/or unstable:

    float: none;
    div#sidebarColumn {
    float: right;
    width: 200px;

    Cynglas and Deltawing1 have it right that there are serious problems with “float”. The first is that there is no means of linking the floater with any block–in actual printed matter every floater belongs to some block. When that block comes to an end, automatic clearing is right.
    An example comes to mind: one has gone on a trip to Turkey, and come home with pictures to illustrate one s story. The best is if the picture appears first as with “align=top”, and the words flow around it, but only the words of that block. If another picture soon follows, if it fits left or right of the earlier, it is set there, but if not, it causes a break until it fits, and so on to the end.
    Eric s comments about keeping track of width are only witness to “float” s faults.
    The name “float” is quite misleading: really the floater s position is, in a manner, rounded or fixed. When one sees in print “see sidebar”, the sidebar s position is “rounded” into fitting into a page, or column, or ….

    I assume a large portion of this is now incorrect or am I completely wrong in understanding, specifically, specifying a width for floated elements is a must.

    From what I’ve seen in the last few years it is the norm to omit the width to intentionally “ask” the browser to adjust the width of an element to that of it’s contents, no?
