Designing CSS Buttons: Techniques and Resources

Advertisement

Buttons, whatever their purpose, are important design elements. They could be the end point of a Web form or a call to action1. Designers have many reasons to style buttons, including to make them more attractive and to enhance usability. One of the most important reasons, though, is that standard buttons can easily be missed by users because they often look similar to elements in their operating system. Here, we present you several techniques and tutorials to help you learn how to style buttons using CSS. We’ll also address usability.

Links vs. buttons

Before we explain how to style buttons, let’s clear up a common misconception: buttons are not links. The main purpose of a link is to navigate between pages and views, whereas buttons allow you to perform an action (such as submit a form).

In one of his articles, Jakob Nielsen writes about command links2, which are a blend of links and buttons. But he recommended that command links be limited to actions with minor consequences and to secondary commands. To learn more about primary and secondary commands (and actions), check out Primary and Secondary Actions in Web Forms3 by Luke Wroblewski. To learn more about the differences between links and buttons, read Creating Usable Links and Buttons624 at UXBooth.

Basic Styling

The simplest way to style links and buttons is to add background color, padding and borders. Below are examples of the code for the link, button and input (“Submit”) elements.

<a class="button" href="#">Sample button</a>
  <button class="button" id="save">Sample button</button>
  <input class="button" value="Sample Button" type="submit" />
.button {
  padding:5px;
  background-color: #dcdcdc;
  border: 1px solid #666;
  color:#000;
  text-decoration:none;
}

This simple code minimizes the visual differences between links and buttons. And here are the rendered examples of the code above:

The important thing to note is that these three elements render differently with the same CSS. So, you should style these elements carefully to ensure consistency across your website or application.

Images

Adding images to buttons can make the buttons more obvious. Sometimes the image itself clearly communicates the purpose of a button; e.g. a loupe icon for searching or a floppy disk icon for saving. The easiest way to add an image to a button is to use a background image and then position it accordingly. Below are our examples with a checkmark icon.

.button {
  padding: 5px 5px 5px 25px;
  border: 1px solid #666;
  color:#000;
  text-decoration:none;
  background: #dcdcdc url(icon.png) no-repeat scroll 5px center;
}

Button States

In addition to their default state, buttons and links can have two other states: hover and active (i.e. pressed). It is important that buttons appear different in different states so that users are clear about what is happening. Any element in a hover state can be styled by invoking the :hover CSS pseudo-class.

a:hover {
  color:#f00;
}

Though very important, the active state is rarely implemented on websites. By showing this state, you ensure that your buttons are responsive and send a visual cue to users that a button has been pressed. This is called isomorphic correspondence, and it is “the relationship between the appearance of a visual form and a comparable human behavior” (Luke Wroblewski, Site-Seeing5). The article Pressed Button State With CSS6 elaborates on the importance of the active state.

a:active {
  color:#f00;
}

There is yet one more state, one that is seen when navigating with the keyboard: the focus state. When the user navigates to a button using the Tab key, it should change appearance, preferably to have the same appearance as the hover state.

a:focus {
  color:#f00;
}

The examples below shows the common way to style button states. The hover state is a bit lighter than the normal state, while the active state has an inverted gradient that simulates a pressed action. Although you need not limit yourself to this styling, it is a good place to start.

Screenshot

We should talk about how to handle the outline property7 for the :active and :focus states. Handling this property well is important for the experience of users who employ the keyboard as well as the mouse. In the article Better CSS Outline Suppression8,” Patrick Lauke shows how buttons and links behave in different combinations of states and explains why the outline property should be invoked only with the :active state.

Screenshot

The blue “Buy now” button on Apple.com9 has a slightly lighter background for the hover state and an inset style for active state. Even the main navigation button on Apple’s website implements all three states.

Screenshot

Although it doesn’t implement the active state, this fancy button on Tea Round10 has a nice fading effect on hover.

Screenshot

The “Read more” button on UX Booth11 turns green on hover and moves down one pixel in the active state, which simulates the effect of pressing a button.

Sliding Doors: Flexible Buttons

One important consideration needs to be made when styling buttons: scalability. Scalability in this context means being able to stretch a button to fit text and to reuse images. Unless you want to create a different image for each button, consider the “sliding doors” technique. This technique enables you to create scalable, rich buttons.

Screenshot

The principle involves making two images slide over each other, allowing the button to stretch to the content. Usually, this is done by nesting a span element within a link. As shown in the image above, each element has its own background image, allowing for the sliding effect. The two code snippets below show the structure and basic styling for this effect.

<a href="#"><span>Typical sliding doors button</span></a>
a {
  background: transparent url('button_right.png') no-repeat scroll top right;
  display: block;
  float: left;
  /* padding, margins and other styles here */
}
a span {
  background: transparent url('button_left.png') no-repeat;
  display: block;
  /* padding, margins and other styles here */
}

The advantages of this technique are that it:

  • Is an easy way to create visually rich buttons;
  • Ensures accessibility, flexibility and scalability;
  • Requires no JavaScript;
  • Works in all major browsers.

Screenshot36

CSS Sprites: One Image, Not Many

With CSS Sprites, one image file contains multiple graphic elements, usually laid out in a grid. By tiling the image, we show only one Sprite at a time. For buttons, we can include graphics for all three states in a single file. This technique is efficient because it requires fewer resources and the page loads faster. We all know that many requests to the server for multiple small resources can take a long time. This is why CSS Sprites are so handy. They significantly reduces round-trips to the server. They are so powerful that some developers use CSS Sprites for all their graphics. The Holy Sprites37 round-up on CSS Tricks offers some very creative solutions.

The example below shows the simplest use of CSS Sprites. A single image contains graphics for all three button states. By adjusting the background-position property, we define the exact position of the background image we want. The image we’re choosing to show here corresponds to a background position of top: -30px and left: 0.

Screenshot

a {
  background: white url(buttons.png) 0px 0px no-repeat;
}
a:hover {
  background-position: -30px 0px;
}
a:active {
  background-position: -60px 0px;
}

CSS 3: Buttons Of The Future

CSS 3 allows us to create visually rich buttons with just a few lines of code. So far, this is the easiest way to create buttons. The downside of CSS 3 is that it is currently supported only by Firefox and Safari. The upside is that buttons styled with CSS 3 degrade gracefully in unsupported browsers. By using the browser-specific properties -moz-border-radius (for Firefox) or -webkit-border-radius (for Safari), you can define the radius of corners. Here are a few examples of what can be done with the border radius property.

Screenshot

For better results, you can combine CSS 3 rounded corners with the background image property. The example below shows a typical button with a gradient image, the first without rounded corners, and the second with.

Screenshot

Compared to sliding doors, this technique is far simpler. However, if you want to maintain visual consistency across all browsers, then use sliding doors, because it works in all major browsers, including IE6. To learn more about the capabilities of CSS 3, read CSS 3 Exciting Functions and Features: 30+ Useful Tutorials41.” And here are a few good tutorials on styling buttons with CSS 3 features.

Instant Tools: Are They Useful?

Tools exist for creating buttons, such as Easy Button and Menu Maker49 and My Cool Button50, and for creating CSS Sprites, such as CSS Sprite Generator51, but the question is, do they really help you create buttons that fit your needs. Although they are configurable and easy to use, your creativity and control over the results are limited, which makes for average-looking buttons. Using one-size-fits-all buttons is not a good idea.

The solution is to use Photoshop (or a free alternative52) and the proven techniques described in this article. If you are a beginner with Photoshop, here are several excellent tutorials on creating amazing buttons.

Buttons And Usability: Instead Of Conclusion

The techniques described above can help you create stunning buttons. However, because they play a critical role in website usability, the buttons should meet some key principles:

  1. First consider the labeling. Always label buttons with the name of the action that the user is performing. And always make it a verb59. A common mistake is to label buttons “Go” for various actions such as searching, sending email and saving. Labels should also be short and to the point; no need to clutter the user interface.
  2. As mentioned, include all button states (default, hover, active) to provide clear visual cues to the user as to what is happening. Button outlines should remain in the active state only.
  3. Clearly distinguish between primary and secondary actions. The most important action should be the most prominent. This is usually done by giving primary and secondary actions different colors.
  4. Pay close attention to consistency. Buttons should be consistent throughout a Web application, both visually and behavior-wise. Use CSS sliding doors for reused buttons or CSS 3 rounded corners to maintain consistency.
  5. Though obvious, we should note that the entire button area should be clickable.

The articles below provide even more usability guidelines and best practices for designing buttons.

    Is it me or is the background-position information incorrect in the example on ‘CSS Sprites: One Image, Not Many’. I think the background-position values should be reversed, the first value specifies the horizontal not the vertical.

    I wouldn’t have noticed this had I not been using this article as a source of great information. Thanks!

    Hi, I’ve read this article over and over again just to get a grasp on how to make a button for my menu in my website through CSS. The more time I spent reading article, the more confused I become.

    I am not a web designer and CSS topic is just too much for me to take on for now though I have a little knowledge… All I want is for my website to look presentable.

    Can anybody from here guide me step by step on how to make click-able buttons for my menu instead of just a plain text?

    I am a fast learner so I just need guidance where to go first and what to do first :) I promise.

    Thank you very much. By the way, this is my website that I want to beautify. outsourcemanager.net

    As you mentioned – it depends. If you want to grab users’ attention, you would consider restyling default buttons’ appearance. With their default styling you certainly wouldn’t be able to grab almost any attention. But that’s not the only case. You can restyle buttons in order to emphasize primary actions, which is very important usability factor.

    But I do agree that poorly styled buttons can be easily missed.
