    Universal selectors


    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 namespace

    • ns|* - matches all elements in namespace ns
    • *|* - matches all elements
    • |* - matches all elements without any declared namespace


    *.warning {color:red;}
    *#maincontent {border: 1px solid blue;}
    <p class="warning">
      <span lang="en-us">A green span</span> in a red paragraph.
    <p id="maincontent" lang="en-gb">
      <span class="warning">A red span</span> in a green paragraph.
