Universal selectors
The CSS universal selector (*) matches elements of any type.
css
/* Selects all elements */
* {
color: green;
}
The universal selector is a special type selector and can therefore be namespaced when using @namespace. This is useful when dealing with documents containing multiple namespaces such as HTML with inline SVG or MathML, or XML that mixes multiple vocabularies.
ns|*- matches all elements in namespace ns*|*- matches all elements|*- matches all elements without any declared namespace
Syntax
css
* { style properties }
The asterisk is optional with simple selectors. For instance, *.warning and .warning are equivalent.
Examples
CSS
css
* [lang^="en"] {
color: green;
}
*.warning {
color: red;
}
*#maincontent {
border: 1px solid blue;
}
.floating {
float: left;
}
/* automatically clear the next sibling after a floating element */
.floating + * {
clear: left;
}
HTML
html
<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>
Result
