Like others said the best start is to test yourself on your home pc using some of free hostings. Also, it is very important to read about web design, it is not enough to learn a couple of things and think that u know everithing. read, read, read!
Hi,
I do agree with you as, one of friend who started web designing make web designs and do all sort of testings on it as this makes your work very efficient and also you can create lot of good designs.
