how do we perform validation through HTML 5

Question

for instance we have email id which is compulsory how to we check it

Answer 1

Validation is much more easier if you use JavaScript. You can also search for "AJAX" to do that. HTML is not more than just a markup language while JavaScript is a scripting language, that is it can do many things possible, same as programming.

Answer 2

this would increase the load on our server so to reduce its load we are trying to do validation at client side
