CSS Aide

CSS Aide is a reference app for Cascading Style Sheets.

It features:

• 9 selectors
• 23 pseudo classes
• 4 pseudo elements
• Over 100 CSS properties

For each property, CSS Aide contains:

• A description of the property.
• Explanations of its possible values
• A code example showing both CSS and HTML
• A visual website view of the code example

As well as the basics: fonts, borders, backgrounds and so on, CSS Aide contains many of the newer CSS 3 properties, including animations, transitions, and columns.

You can choose to view by CSS 2.1 or CSS 3 which allows for easy lookup of values.
