Hello everyone.I am new to that forum.I want to learn web design advance.How will I learn html 4 and css3.
Welcome, now please never ask that question again. Check out w3schools.com, a simple google search would have landed you there immediately.
If you want to learn web design advance then my suggestion is- try to learn XHTML 1.0 / CSS 2.1 because they are totally cross browser friendly and also mobile browser friendly. and after that you can improve your skills to html 4/5 or css 3 by taking little help from w3school. remember there are lots of web browsers with different versions out there, so you have to think about them. best of luck.
