We continue to review text and source editors for designers and web-developers. After a thorough consideration of WYSIWIG- and source code editors now it’s time to take a closer look at applications for advanced CSS-coding. Reason: while numerous HTML-editors offer more or less advanced CSS-support there are also allround-CSS-editors which offer a sophisticated integrated development environment for CSS-coding.

Of course, real CSS ninjas accept nothing but a minimalistic Notepad or some sophisticated source code-editor. In fact, CSS-editors are often considered to be unnecessary and superflous — after all, you can do the same in your favourite text editor. And sometimes this is true — while there are some really bad HTML-editors there are also some even worse CSS-editors. Particularly code autocompletion tools are extremely good at bloating the code to extremes, making the resulting stylesheet unnecessary complex and hard to maintain. Why would someone purchase a CSS-editor to raise the maintenance costs afterwards?

Yet CSS-editors can be helpful; furthermore, you can effectively use them in different settings by developers with different skills. Web professionals can use a CSS-editor to improve workflow and get all useful CSS-tools provided by one single application. Newbies can easier learn CSS by analzying stylesheets and using live-editing to understand how the design is built up and what is actually going on behind the scenes. In either case you should make sure you know what you are doing and not end up producing quick’n'dirty stylesheet.

Why the heck do I need a CSS-editor?

Well, actually you don’t need one. But you may want to use one to make your workflow more effective. The main advantage of CSS-editors lies in an integrated development environement they offer to web-developers. The main task of a CSS-editor is to combine the editing features of CSS-stylesheets, HTML-source code and the site layout effectively within a compact interface. However, often CSS-editors go even further.

Apart from coding functionality good CSS-editors offer assisting tools for debugging and testing as well as useful features such as live-editing, preview in different browsers, advanced code browsing, code formatter, beautifier and compressor, validation, built-in CSS-reference and project management tools. Combining these features together you get an arsenal of useful tools all ready to hand in front of you.

Some editors also enable you to organize parts of the code into folders and filter the stylesheet easily which simplifies maintenance and makes the source code easier to scan. Another useful feature is instant style sheet preview with Internet Explorer or FireFox which is hard to find in any “standard HTML-editor. Furthermore, with CSS-editors it’s easy to analyze code problems using a code inspector and decompose a stylesheet using the so-called “X-Ray” function.

To put it short: the main advantage of a CSS-editor is that it offers an integrated, compact environment for CSS-design and enables a quick and effective coding workflow which would require a dozen of external tools otherwise. So which CSS-editors are available?

Xyle

Xyle (Mac)
This advanced editor allows developers to edit web-sites on the fly using the embedded stylesheet. Similary to Web Developer’s Toolbar you can modify the CSS-code and the changes will be displayed immediately in the browser window. Compared to Web Developer’s Toolbar, with Xyle you have further useful features such as selectors tree view, syntax highlighting and advanced file management.

Large preview

In Browser Mode you can browse the Web using Safari’s rendering engine. In Selection Mode, clicking into any part of the web page displayed will reveal the exact portion of the HTML and CSS sources that are responsible for the contents and formatting of that part.

In Cascade mode, Xylescope displays not only the style rules that apply to the currently selected element, but also all rules applying to ancestors of the selected element. When debugging, with
Xylescope you can simply select a “problematic” element in Cascade Mode to see which rules are actually applied and which ones are overridden, including those that are applied to ancestors of the
given element! Xylescope displays the specificity of selectors to indicate why rules have precedence and dims overridden CSS properties to improve clarity. Xylescope also offers integration with external text editors such as BBEdit.

Price: $19.95. A trial version is available. A nice solution without advanced features such as validation, compressor or beautiful offer to an optimal price.

Some of Xyle’s features

• Automatic formatting
• Selector matching
• filter large CSS files using smart groups
• built-in DTD viewer

Stylizer

Stylizer (Windows)
Two things make Stylizer a slightly different mindset than the others: it uses a grid interface instead of a text editor, and it has Firefox and IE embedded, so when the user changes the CSS, it’s propagated right away to the browser. The grid system makes CSS feel like “CSS on rails”, because it makes it impossible to have any CSS errors. It lets Stylizer do things such as a Firebug-like element inspector that lets the user diagnose and edit in the same place, and an editable, spotlight-style filtering system.

In Stylizer dimensions can be adjusted on the fly. To change a height, a margin, or a background-position, the user can literally click on the value, drag the mouse around, and watch the element be manipulated in real time. Colors are the same. The user can click on them, drag the mouse, and see the color of the text, background, or border change in the browser, in real-time, creating a “Photoshop for the web” type feeling. Stylizer Basic is free. The premium version (Price: $69.95) isn’t that different, however in a free version it’s impossible to filter a style sheet to only show rules with specified content.

Rapid CSS Editor

Rapid CSS Editor (Win)
This editor supports developers with a syntax highlighting, autocompleter and a code inspector which ensures that the produced code is correct. You can use built-in CSS- and HTML-references to quickly look up the syntax and attributes of a given selector or tag. A color tool enables designers to pick the right color without switching to color application and observe the result live using the Style Sheet Preview with Internet Explorer and Firefox. A file manager can also take care of uploading CSS-files via FTP. Furthermore, you can make use of an advanced clipboard to keep multiple code fragments ready to hand. The editor costs $29.85. A trial-version is available.

Some of Rapid CSS’s features

• Syntax Highlighting for CSS and HTML documents
• CSS Checker and Validator
• CSS Code Explorer

TopStyle

TopStyle (Win)
The CSS-HTML-editor TopStyle is available in its Lite-version within the HTML-editor Homesite — however, there is also a sophisticated full version for professional web-developers. With TopStyle developers get a number of features which aren’t available in other editors. For instance, with integrated HTML-tidy you can easily convert depricated HTML-tags in valid XHTML. The integrated Style update replaces deprecated tags such as the <font>-tag with respective valid CSS-rules. The Clip Library contains frequently used code-snippets. A split window enables a direct browser-comparison displays site presentation in Internet Explorer and Mozilla. You can also vary the Doctype-definition to find out how different DTDs influence the layout in different browsers.

Probably the most powerful tool in TopStyle is Style checker. Not only can it validate style sheets and hence ensure the correct layout presentation in different browsers. It can also predict bugs in popular browsers which may appear despite the valid CSS-code. You can also forward CSS-stylesheets to W3C CSS Validation Service to fix the problems which haven’t been found by TopStyle. The full version costs $79.95. Warning: the lite-version can’t be updated. Windows-only.

Some of Top Style’s features

• HTML, xHTML and CSS Editing in a Single Program: HTML attributes are categorized so you can quickly see which are required, and it generates XHTML-compliant markup with a simple toggle.
• Easy Navigation Between Documents: Click an HTML class attribute to navigate to the definition of that class in an external style sheet or click an anchor tag or CSS link to open the linked file for editing. You can even click on an < img > tag to open the image file in your favorite image editor.
• Element and Attribute Validation as You Type: All of the classes are defined in your style blocks and external style sheets, so assigning a class to an HTML tag is a very simple task.
• Style Checker: Validate your style sheets against multiple browsers, flagging any invalid properties or values it finds. You can also pass your style sheets directly to the W3C’s CSS Validation Service, so you can quickly check against the official CSS specifications.
• Style Upgrade: A quick, reliable way to replace all deprecated (outdated) HTML markup - including the long-abused HTML < font > tag - with equivalent CSS.
• HTML Tidy Integration: Make the move to XHTML painless with the built-in Tidy configuration, which converts HTML to XHTML with a single click!
• Site Reports: See at a glance where styles are used in your site. Find out where you’ve applied style classes that aren’t defined in any style sheets, or see what style classes you’ve defined that aren’t being used.
• Full Screen Preview: Split the preview between Internet Explorer and Mozilla for an immediate look at browser differences. You can even change the !DOCTYPE of each preview panel on-the-fly to see how different document type declarations affect your layout.
• Integration with W3C HTML Validation: Results of the validation are displayed within TopStyle, with hyperlinked line numbers that synchronize with TopStyle’s editor.

CSSEdit

MacRabbit CSSEdit (Mac)
Similarly to XyleScope, CSSEdit offers real-time styling of stylesheets. Even when a dynamic web-application is powered by a complex database or makes use of AJAX, you can style and analyze it without the hassle of uploading or refreshing (online and offline — this is not the case in Web Developer’s Toolbar). Selector Builder lets you describe what elements to style in plain English. Intelligent CodeSense analyzes CSS and CSS behavior to offer smart, context-sensitive suggestions.

Large preview

X-ray Inspector shows you what styles apply to a HTML-document. You can also validate your sheets against W3C standards and use project management tools (Milestones etc.) to improve your workflow. Among other things CSSEdit automatically adds brackets, (semi-)colons and appropriate spacing for you. If you encounter a style sheet from someone who didn’t have that luxury, you can always do a Re-Indent to apply your spacing settings. Besides, it has a live-preview feature and the clipboard library for frequently used code snippets.

There is an EditCSS plugin for Firefox as well as CSSEdit bookmarklets. You can start editing any site’s style sheets with a single click in your browser’s Bookmarks bar, and then use the advanced CSSEdit’s editing. The tool has a beautiful, intuitive interface which is very compact yet very well organized and nice to work with. EditCSS costs 29.95 Euro ($47). There is also a trial-version available for free download.

Style Master

Style Master (Win / Mac)
Since this WYSIWIG-CSS-editor calls itself a master it needs to have some nifty features which let the tools stand out from the crowd. In fact, Style Master enables both newbies and professionals to create valid and semantically correct stylesheets. The selectors can be grouped by alphabet, category or current settings. The editor has an integrated color picker, various templates, wizards and validation tools. Hence, the professional can work easily and effectively while newbies don’t have to figure out their way through CSS-tricks to create flexible CSS-based web-sites.

Hence you can simply take over a CSS-skeleton and define the rules — all selectors are already listed. You can also use a W3C-example-stylesheet which defines the style of almost every possible HTML-tag, e.g. the leading of headlines <hx>.

Style Master allows you to use online documents (and those running on local servers) as preview documents. You can then use all the features of the Design Pane, like X-Ray, to design your styles sheets. The editor is simple, intuitive and clean. Price: $59.99.
