The group selector:


We can also select multiple-element at a time of HTML during the styling.

Example:

p{

color:red;

background-color:white;

font-weight:bold:

h1{

color:red;

background-color:white;

font-weight:bold:

}

h2{

color:red;

background-color:white;

font-weight:bold:

}


We can also style by grouped selecting due to saving time, and space.

The comma(,) is used as separator of grouped selector 

p, h1, h2{

color:red;

background-color:white;

font-weight:bold:

}

In this way, we can choose multiple elements that needed to be the same styling on the webpage.
