The body is where you put all the information you want to make available for your audience. In the Body you can also insert graphics, sound files, video files, etc. The Footer contains information about the page and its author. Some of the things you can list here are e-mail address, copyright notices, home or business address, etc. The Footer is optional meaning that you can put the same information you would put here in the Body of the document.
Some tags contain values called attributes.
Some Attributes provide sources or destinations for links, other add physical descriptions of a display object such as a graphics file, here is an example. The HTML tags are in red and their attributes are in blue . It is important that when writing HTML code you use comments or notes for future reference, that way you'll know what the code does or what it is for. Text inside the brackets will be ignored by the browser. See how the example below works.
