Styling your page with CSS
id and class attributes
Two of the most used attributes in HTML is id and class.
They are important to distinguish and group different elements. And become particularly important in CSS styling.
Note:
id
Ids cannot repeat in the same file. They are used to distinguish tags
The symbol for id is: #
<div id="square" style="background:black; color:red; width:400px; height:100px"/>
Id can server as a anchor (link) point within each page.
class
Classes can be used INFINITE TIMES in a file. They are used to group tags.
The symbol for class is: #
<p class="text">A</p>
<p class="text">B</p>
<p class="text">C</p>
