Why does the class class in css have two names? Or what does it mean? _html/css_WEB-ITnose

What does it mean to write 2 names in a css class?

<div class="path cl"></div>

What do path and cl mean? Why are there two? Please explain.

You can have multiple class definitions act on the node. If there are the same attributes, the later ones will overwrite the previous ones.
