0Selectors help to select an element to which you want to apply a style. For example below is a simple style called as ‘intro” which applies red color to background of a HTML element.
<style>
.intro
{
background-color:red;
}
</style> To apply the above “intro” style to div we can use the “class” selector as shown in the below figure.
<div class="intro"> <p>My name is Shivprasad koirala.</p> <p>I write interview questions.</p> </div>
