!important flag

The !important flag gives precedence to a style or any CSS property for which it is specified.

Syntax

selector {
	property: value !important;
}

Let's make blue paragraph font color take precedence over green color:

<div>text</div>

div{
	color: blue !important;
	width: 600px;
	height: 100px;
	font-size: 20px;
}
div {
	color: green;
}
