HTML forms part of a large more
powerful mark-up language called SGML. In an effort to harness  the power of SGML  without loosing the simplicity of HTML, the
W3C has developed Extensible Markup Language, or XML that can be used to create
your own mark-up languages, specifically suited to your topic.  SWITCHING
BETWEEN WINDOWS While working on browsers, it is easy to switch between
various windows software. This is so since both the commonly used browsers are
windows based. For switching between one software or browser to another we simply
use the option of pressing. This is simple. Else you can minimize one
application to see another. The choice is yours.

HTML COMMAND TAGS

For all practical purposes, HTML
tags are written within the less than and greater than signs, also known as
angle brackets. These signify the opening and closing of the commands. The
Command for opening and closing are the same but for one exception the closing
one has a attached to it.  QUOTATION MARKS Mostly all values
should be enclosed in straight marks. However you can omit the quote marks if
the value only contains letters digits. There is no restriction on the number
of spaces given by you. HTML always finds out standard ASCII set characters can
be used it is the concept of entering p tag while being of each para. Each new
para would begin on new line. It goes without saying that the would always have
to be flowed the space in the browser each browser has browser has its concept
which you will learn later. Beside the usual ASCII set of characters, HTML
supports other character too. The standard ASCII set characters can be used as
it is and will be displayed as it is in the browser. There are four symbols
that have special meaning is HTML documents. These are four symbols double
quotation mark and ampersand. If you simply type them in your HTML documents,
the browser may attempt to interpret them. To show the symbol themselves, use a
name or number code.

TAGS WITH AUTOMATIC LINE BREAKS

Block-level tags generally include
automatic, logical line breaks. For example, you don’t need to use a new
paragraph tag after a header, since header automatically includes a line break.
In fact, you only need to insert a new paragraph tag if you’re using the tag to
apply styles. Some common block level tags are P, H1, BR, UL and TABLE. Inline
tags that affect only begin on a new line some common inline tags are EM, B,
and IMG. Attribute can have values. In some cases, you must pick a value from
small group if choices. For example, the CLEAR attribute for the BR tag can
take values of left, right, or all. Other attribute are stricter about the type
of values they accept. For example, the HSPACE attribute of the IMG tag will
accept only integers as its value, and the SRC attribute of the IMG tag will
only accept URLs for its values.
