Before you begin building your page, you'll need to decide on a basic page layout. To do this, just sit down with some old-fashioned paper and a pencil and start sketching, blocking out the page's elements. You may be itching to get coding, but by drawing your site out first you can rearrange designs to your heart's content without having to code and recode. If you want an image to show up on the left side of the page, a certain word to appear bold, or another word to link to an outside resource, you'll use HTML tags to do it. There are five important rules for coding with HTML tags.
Most tags come in pairs and surround the material they affect.
First tag on, last tag off. Tags are embedded, so when you start a tag within another tag, you have to close that inner tag before closing the outer tag. Many tags have optional attributes that use values to modify the tag's behavior. Remember, too, that HTML is always evolving, and older browsers often don't support the newest tags. When a browser encounters an HTML tag it doesn't understand, it will usually ignore both the tag and the material the tag affects.
