Summary
An asterisk (*) is the universal selector for CSS. It matches a single element of any type. Omitting the asterisk with simple selectors has the same effect. For instance, *.warning and .warning are considered equal.
In CSS 3, the asterisk may be used in combination with namespaces:
ns|*- matches all elements in namespace ns*|*- matches all elements|*- matches all elements without any declared namespace
Examples
* [lang^=en] {
color:green;
}
*.warning {
color:red;
}
*#maincontent {
border: 1px solid blue;
}
<p class="warning"> <span lang="en-us">A green span</span> in a red paragraph. </p> <p id="maincontent" lang="en-gb"> <span class="warning">A red span</span> in a green paragraph. </p>
