Is It necessary to use css coding for creating a web page??

Question

if it's necessary when we should use I.e, at for what purposes??

Answer 1

no it's not necessary to use css unless you want your page to look gorgeous.
I mean css is only for style.
html gives structure to your webpage and css adds style to it. want more? use java script to give your page dynamic functionality.
you should use css only if you want to add style which is very essential for good looking webpages. you must learn it though if you wish to go into webdevelopment
