Pseudo selectors

Pseudo selectors can be used to apply style only when some conditions are fulfilled.

Pseudo selectors are preceded by a colon and can be combined:

<Style name="Table:even:input" >
<Style name="Edit:focus" >
<Style name="Edit.important:focus" >

When combining several pseudo selectors, the style will be applied if all pseudo selector conditions are fulfilled.

Depending on the type of the front-end, some pseudo selectors are meaningless, or unsupported. See the table below to check which pseudo selectors are supported on your front-end platform.

Pseudo selectors have different priorities; the style with the most important pseudo selector will be used when several styles match.

Table 1. Pseudo selectors for presentation styles
