MIT LicenseMIT

CSS3_Syntax

Announcement: For ST3 users, this package has been replaced by CSS3. This package will be removed some time after Sublime Text 3 is released.

Features

  • Comprehensive: near complete support for CSS3, based on the latest draft specs, support for many vendor-prefixed CSS extensions (e.g. -moz-, -ms-, -webkit-)
  • Forward-looking: support for upcoming features like variables, CSS animation, and @supports
  • Modern: deprecated or obsolete parts of CSS are flagged as such
  • Faithful: extremely close adherence to the W3C specification, with minor deviations due to technical limitations (for non-trivial deviations read below)

Installation

  1. Install Package Control
  2. Mac: cmd+shift+p → Package Control: Install Package → CSS3 Syntax
    Windows/Linux: ctrl+shift+p → Package Control: Install Package → CSS3 Syntax

After you've installed the plugin, open any CSS file and set the syntax to CSS.

  • Mac: cmd+shift+p → Set Syntax: CSS3
  • Windows/Linux: ctrl+shift+p → Set Syntax: CSS3

Set CSS3 Syntax as Default

  • WARNING: This may break extensions that only recognize the default CSS syntax, such as Autoprefixr. A workaround, shown here, is to switch the syntax back to CSS when you want to run Autoprefixr.
  1. Open a CSS file in Sublime Text
  2. Navigate to View → Syntax → Open all with current extension as... → CSS3

After these steps, any CSS file you open in the future will be highlighted using CSS3 Syntax.

Limitations

  • No support for the following prefixes
-ah- -apple- -atsc- -hp- -ibooks-
-khtml- -mso- -o- -prince- -rim-
-ro- -tc- -weasy- -xv-
  • Incomplete support for vendor-prefixed CSS extensions (we're adding more as we find them)

Deviations from the Spec

All Properties Must End with a Semicolon

CSS doesn't require this, but it's a good practice. Semicolons help the highlighter distinguish properties and values. Without a semicolon, the highlighting could be off.

All Properties Must be Written in Lowercase

The spec says that HTML tags, properties, values, function names, and more should be matched case-insenstively. However, this syntax highlighter only matches lowercase text. If this bothers enough people, we can work to include matching uppercase text as well.
