Wow! Thanks everyone for answering! I see I'm the opposite of almost everyone here... All of you seem to be extremely good at coding and programming. I bet your designs are very good too... As for me, it's just that I'm too picky with colours and designs. It's frustrating to have an idea in your head and not be able to make it.
Thanks for the advice, everyone. I got a friend of mine to do the website for me. She refused to receive any money, and I usually send her original drawings as a payment. Only problem is I depend on her schedules. If she's busy, my website is over. So I thought that, even if she does the bulk of it, her being the coder, if I could at least manage updates and all that, I would be free to go on with the work when she was busy. When someone refuses to get paid, you can't demand much. And when you don't have money to pay a pro, you can'd demand anything more.
I'm going to have a good look at trying the gradient background with CSS. And I'm going to all your recommended links about the colours. The colour stuff is something really important to me... I know the important thing is content, but I like the site to be colour-matching, at least.
And, totally off-topic, but unavoidable: Light has extremely good taste in comics
