css - .class a:hover vs .class:hover a -


couldn't find answer i've been wondering about.

is there difference between .class2 a:hover {} , .class2:hover {}? or preference 1 on other?

i've been using .class2 a:hover {} alter anchors on anchor hover (ie: anchor text color), when wanted alter div held anchor (ie: anchor color , div background-color both change on hover), had use .class2:hover {} work. in doing so, got confused difference because between 2 written similarly.

thanks!

edit
edited question more clear. untwisting brain :)

my understanding this:

.class2 a:hover target hyperlink tags within .class2 elements when a tags hovered.

.class2:hover a target hyperlink a tags within .class2 elements when .class2 hovered.

the distinction element hover in order change styling rules.

example:

.box{    background: red;    width: 50px;    height: 50px;    margin-bottom: 10px;  }  .case1 a:hover {    background: blue;  }      .case2:hover {     background: green;  }
<html>    <body>      <div class="box case1"><a href="#">case 1</a></div>      <div class="box case2"><a href="#">case 2</a></div>    </body>  </html>

in case, want hover .class2 element or a?
