diffrence between class and id

[anandgp]

Hi,

 

I am not able to understand the difference between a class and an id. Both of them define property and it's value.

 

 

.container {

min-width: 900px;

}

#top {

background-color: #84c754;

color: #ffffff;

padding: 15px;

}

--------------------------------------

<div class="container">

<div id="top">

<h1>Welcome to My Homepage</h1>

</div>

</div>

Regards,

-Anand

The id is used when you want to reference an element that is unique, when there is only one on the page. A class can be used to give a same style to multiple different elements.

 

The id is also used by Javascript to easily access an element.
