Komodo 6 Now Supports HTML5 and CSS3

Komodo 6 includes support for the latest and greatest web technologies,like HTML5 and CSS3.


Komodo already provides a slew of great features for working with HTML, such as

On top of these great features Komodo has added new tag and attribute completions for the HTML5 specific elements, like:

  • <article>
  • <canvas />
  • <video />

Upon opening HTML files, Komodo automatically detects HTML5 content from the “<!doctype html>” declaration at the top of the file, or you can also change the language to HTML5 through Komodo’s statusbar.

JavaScript support has been updated to include the new HTML5 APIs – just enable the “html5” CodeIntel API catalog and you’ll have new completions and calltips showing all the HTML5 API goodness.

CSS handling is already extremely helpful in Komodo, providing

  • code intelligent completions and calltip information (screenshot below)
  • syntax checking
  • color preview on mouse over
  • advanced css color editing

Komodo’s CSS handling has been updated in order to provide completion and calltip information for the latest CSS specification – CSS3. As well as CSS3, Komodo now includes browser specific extensions as well. There is no need to rack your brain trying to remember all of the possibilities for Mozilla (-moz-), Webkit (-webkit-) and Internet Explorer (-ms-) … ah, let Komodo do the remembering for you.

Here is a screenshot of Komodo 6 providing CSS completions for the webkit specific CSS extensions:
