You have made a good start on your site. Stick with it. HTML code might look complicated or intimidating at first, but it isn't really. Try some of the tutorials that are available online and I'm sure you'll get a hang of things in no time. I highly recommend the W3C Schools Online Web Tutorials.
It is always a good idea to check your site against a multiple browsers. What works for one doesn't always works on another. or you will get little variations like how different browsers handle paragraphs and breaks differently. That sort of thing.
Best of luck on your site. You're off with a good start and I can only see things getting better with time.
