Here's a list of different HTML codes and what they do.
<head></head> - Adds a header to your page.
<body></body> - The actual document, there are also various codes that can be put into "<body></body>" to change the color of the text, links, active links, backgrounds etc.
bodybgcolor=color text=color link= color alink=color vlink=color </body>
"bodybgcolor" is the background color for your page, I put color in italics but instead of that, put in a color of your choice, that goes for "text" which is your text color, "link" which is the color of your link text (text that links a page to a different page) "alink" which is the active link (a link that has already been used) and "vlink" the visited link (if the user has already clicked on the link and went to the linked page, the link changes to this color)
BACKGROUND="http://www.putwebsitehere.com/picturename.jpg"</body>
This will add a background image to your site, all you need is to find an image on the net that you want to use as a background, put the site address where I put "putwebsitehere" and the image name where I put "picturename" and you're set. All you need to remember is to always put quotation marks on the site address.
<b></b> This will bold your text.
<EM></EM> This will put

This tag as you can see determines the text size. Unlike the heading size tag, the higher the number, the bigger the text, I only went up to 7 but you can go higher and make your text bigger if desired.
