HTML and CSS Reference
In-Depth Information
For instance, the following style tells the browser to display the level-1
header text, "I'm so bluuuuoooo!", not only in the <h1> tag style, but
also colored blue and italicized:
<h1 style="color: blue; font-style: italic">I'm so bluuuuoooo!</h1>
Inline styles can be difficult to maintain, because they add more con-
tents to their tags' definitions, making them harder to read. Also, be-
cause they have only a local effect, they must be sprinkled throughout
your document. Use the inline style attribute sparingly and only in those
rare circumstances when you cannot achieve the same effects other-
8.1.2. Document-Level Stylesheets
The real power of stylesheets becomes more evident when you place a
list of presentation rules at the beginning of your HTML or XHTML doc-
ument. Placed within the <head> and enclosed within their own <style>
and </style> tags, document-level stylesheets affect all the same tags
within that document, except for tags that contain overriding inline style
attributes. [*]
[*] XHTML-based document-level stylesheets are specially enclosed in CDATA sections of your docu-
ments. See section 16.3.7 in Chapter 16 for details.
