    Universal selectors Redirect 1

    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 namespace

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

    Example

    *[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>

    Note: Use the universal selector very carefully, as it is the most expensive CSS selector in terms of webpage performance.
