The presentational markup is used to describe the appearance of text. However, it is recommended
-
that we use Cascading Style Sheets instead for handling all kinds of style information.
-
First we have the text styles: bold <b>, italic , underlined <u>, and strike-through <s>/<strike>.
-
Bold and italic are still commonly used text styles, but underlined and both strike-through
-
tags have become deprecated. Like most other tags all of these come in pairs and contains
-
the text that they affect. We can also nest these together to combine different text styles.
-
Next, we have the teletype element <tt> which gives us a fixed-width typeface, just like
-
the preformatted tag. We also have the <big> and <small> elements,
-
which gives a way to change the font size. These elements can be nested several levels
-
deep in order to achieve a greater effect. Lastly, we have elements for rendering text
-
as either superscript <sub> or subscript <sup>.
-
The <font> tag can be used to specify color, size, and typeface of text. The size can be
-
a value from 1 to 7. Or it can be specified relative to the current font size with a plus
-
or minus sign before the number. By default, the standard size is 3. The face attribute
-
can contain one or more font names in a comma separated list. If the user's computer doesn't
-
have the first font it will then try to use the next one and so on. The list here contains
-
common font names grouped together by their appearances.
-
The <body> element provides a number of deprecated attributes for controlling the general appearance
-
of the webpage. We can change the default text color using the text attribute. We can
-
also add a background color or a background image which will be tiled in the background.
