Cascading Style Sheets (CSS) are a collection
of formatting rules which control the appearance of content in a
web page. With CSS styles you have great flexibility and control
of the exact page appearance, from precise positioning of layout
to specific fonts and styles.
CSS styles let you control many properties that cannot be
controlled using HTML alone. For example, you can assign custom
list bullets and specify different font sizes and units (pixels,
points, and so on). By using CSS styles and setting font sizes
in pixels, you can ensure a more consistent treatment of your
page layout and appearance in multiple browsers. In addition to
text formatting, you can control the format and positioning of a
block-level elements in a web page. For example, you can set
margins, borders, float text around other text, and so on.
A CSS style rule consists of two parts—the selector and the
declaration. The selector is the name of the style (such as TR,
or P) and the declaration defines what the style elements are.
The declaration consists of two parts, the property (such as
font-family), and value (such as Helvetica). The term cascading
refers to your ability to apply multiple style sheets to the
same web page. For example, you can create one style sheet to
apply color and another to apply margins, and apply them both to
the same page to create the design you want. |
