You don't really need to know much HTML to create a page, because you can copy bits of HTML from other pages that do what you want, then change the text!
This page shows on the left as it appears in your browser, and the corresponding HTML code appears on the right. The HTML commands are linked to explanations of what they do.
If you want to put a line break at a particular place, you can use the "
" command, or, for a paragraph break, the "
" command, which will insert a blank line. The heading command ("<4>4>") puts a blank line above and below the heading text.
Modifiers are sometimes included along with the basic command, inside the opening command's <>. The modifier does not need to be repeated in the closing command.
