THE ESSENTIAL GUIDE TO CSS AND HTML WEB DESIGN

Introducing the concept of HTML tags and elements
HTML documents are text files that contain tags, which are used to mark up HTML elements.
These documents are usually saved with the .html file extension, although some
prefer .htm, which is a holdover from DOS file name limitations, which restricted you to
eight characters for the file name and three for the extension.
The aforementioned tags are what web browsers use to display pages, and assuming the
browser is well behaved (most modern ones are), the display should conform to standards
as laid out by the World Wide Web Consortium (W3C), the organization that develops
guidelines and specifications for many web technologies.
HTML tags are surrounded by angle brackets??”for instance,
is a paragraph start tag. It??™s
good practice to close tags once the element content or intended display effect concludes,
and this is done with an end tag. End tags are identical to the opening start tags,
but with an added forward slash: /. A complete HTML element looks like this:
Here is a paragraph.
This element consists of the following:
Start tag:
Content: Here is a paragraph.
End tag:
Nesting tags
There are many occasions when tags must be placed inside each other; this process is
called nesting.
