## Description
<section id='description'>
When you create a variable, it becomes available for you to use inside the element in which you create it. It also becomes available within any elements nested within it. This effect is known as <dfn>cascading</dfn>.
When you create a variable, it is available for you to use inside the element in which you create it. It also is available for any elements nested within it. This effect is known as <dfn>cascading</dfn>.
Because of cascading, CSS variables are often defined in the <dfn>:root</dfn> element.
<code>:root</code> is a <dfn>pseudo-class</dfn> selector that matches the root element of the document, usually the <code><html></code> element. By creating your variables in <code>:root</code>, they will be available globally and can be accessed from any other selector later in the style sheet.
