CSS wildcard selector (*)
The wildcard selector is represented by an asterisk (*), and the code is as follows:
*{ Rules }*{
margin:0px;
padding:0px;
}The above is a very common reset code, which can set the outer margins and inner margins of all elements in the page to 0, this has the maximum killing effect. Of course, we can also match all sub-elements under the specified element. The code is as follows:
.antzone *{
border:1px solid #333;
}The above code can set the border of all elements under the class attribute value antzone For border:1px solid #333.
