Question

How to use id and class in HTML and CSS

Answer 1

<!-- index.php -->

echo '<div id="div_id" class="div_class">Your Text Here</div>';

<!-- run: 'Your Text Here' color is #fff -->
<!-- To avoid conflict use id for javascript (getElementById...) and class for css 
<!-- Use id for css if there is no javascript -->

 

/* style.css */

#div_id {
   color:#fff
}
.div_class {
   color:#000
}
