The benefit of this is that you can have the same HTML element, but present it differently depending on its class or ID. In the CSS, a class selector is a name preceded by a full stop (“.”) and an ID selector is a name preceded by a hash character (“#”).

1-You can use class any time and any where you want...but you must use id once 2-with class , you can select many tags , but with id , you can select needle in a hystack ((Select A Tag In Hundreds Tags)) 3-ID is more specific than Class , ID Has 100 score and class is 10 Example: HTML: <p class="color" id="color" > ID Is More Specific</p> CSS: #color { color: red; } .color { color: blue; } So The Paragraph Will Be Red , Because ID Has 90 Score More Than Class
