i am facing lots of dificulties in coding css i code and some actions dont work and also dynamic layout in html

You'll have to ask a specific question, preferably with an example of your code.

Try a website like codecademy.com or dash.generalassemb.ly, they have good beginner web design tutorials. You should have a firm grip on CSS before you start worrying about dynamic websites.
