TopStyle Pro CSS / XHTML / HTML Editor

Want more from your HTML editor?

Keep it, but let TopStyle handle your style sheets - and find out why so many leading HTML editors use TopStyle for CSS editing.

TopStyle is the premier CSS/HTML/XHTML editor for Windows. Written by the creator of HomeSite, TopStyle contains powerful tools for creating standards-compliant sites.

CSS/HTML/XHTML Editing

Now you can edit your HTML documents and style sheets using one great interface!

TopStyle Pro's inspector categorizes HTML attributes so you can quickly see which are required and which are deprecated (outdated). Even better, TopStyle generates XHTML-compliant markup with a simple toggle.

The Style Checker

CSS is actually quite simple, but getting it to work in multiple browsers is a challenge. This is where TopStyle shines!

TopStyle Pro's Style Checker is a powerful tool which validates your style sheets against multiple browsers, flagging any invalid properties or values it finds. It also warns if bugs in popular browsers may cause problems even when your style sheets are perfectly valid.

What's more, TopStyle Pro enables you to pass your style sheets directly to the W3C's CSS Validation Service, so you can quickly check against the official CSS specifications.

Style Upgrade

Make the move to style sheets painless with TopStyle's Style Upgrade feature! This time-saving tool provides a quick, reliable way to replace all deprecated (outdated) HTML markup - including the long-abused HTML <font> tag - with equivalent CSS.

HTML Tidy Integration

TopStyle's integration with HTML Tidy provides a very simple way to use this powerful HTML validation and formatting tool. Make the move to XHTML painless with the built-in Tidy configuration which converts HTML to XHTML with a single click!

Site Reports

TopStyle Pro's powerful Site Reports enable you to 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

Web authors have been waiting a long time for a feature like TopStyle Pro's Full Screen Preview!

Split the preview between Internet Explorer and Mozilla (Netscape Gecko) 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 Service

TopStyle now features integration with the W3C's online HTML validation service. Results of the validation are displayed within TopStyle, with hyperlinked line numbers that synchronize with TopStyle's editor.
