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 of a widget;
• fractional – e.g., to set the opacity of a widget;
• integer – e.g., to set the size of a grid layout;
• percentage – e.g., to set the transparency of colors;
• scalar – e.g., to set the dimensions of a widget; and
• text style – e.g., to style the text of a widget.
