CSS units

Many CSS rules accept units of some sort, as opposed to a set of values.

The different CSS units are:

• color – e.g., to set the background color;
• fractional – e.g., to set a widget's opacity;
• integer – e.g., to set the grid-size;
• percentage – e.g., to set the transparency of the background color; and
• scalar – e.g., to set the width of a widget.
