Cascading<br />
Style rules can be defined in multiple places:<br />
• Inline style sheets are defined in the HTML element tag itself, and apply only to that tag and its children.<br />
• Internal style sheets are defined in the element of an HTML page, and apply to everything on that<br />
page.<br />
• External style sheets are defined in a separate document and can be attached to an HTML page by being<br />
linked to the page in the element. The same external style sheet can be linked to all the pages in<br />
a website, allowing them all to use the same style rules.<br />
• The browser (or user agent) has an internal style sheet <strong>for</strong> displaying websites that don’t have their own.<br />
Browsers often let their users supply their own style sheet to override its default style rules.<br />
Cascading works in this order:<br />
1. If a tag has an inline style sheet, use that;<br />
2. Otherwise, if a page has an internal style sheet, use that;<br />
3. Otherwise, if a page uses an external style sheet, use that;<br />
4. Otherwise, use the browser’s style sheet.<br />
NOTE: If a page includes both an internal style sheet and an external style sheet, the cascade order follows the<br />
order they are referenced in the HTML document: if the external style sheet is referenced after the internal, its<br />
definitions will have precedence.<br />
If this is a fragment of a page<br />
<br />
<br />
<br />
p { font-size: 10pt; color: green; }<br />
<br />
<br />
<br />
<br />
Now is the time <strong>for</strong> all good men...<br />
to come to the aid of their<br />
party.<br />
<br />
<br />
and the file mystyles.css contains this rule<br />
p { font-size: 14pt; }<br />
The page will look something like this:<br />
Now is the time <strong>for</strong> all good men<br />
to come to the aid of their party.<br />
The first paragraph gets its color (green) from the internal style sheet, but the size (14pt) comes from the<br />
external style sheet (since it is referenced last, the size definition here has precedence). The color and size of the<br />
second paragraph are defined inline in the tag and override the other definitions.<br />
Since we didn’t specify a font, this comes from the browser’s default font definition.<br />
It is perfectly legal and reasonable to include more than one external style sheet link in a web page. If this results<br />
in a conflict, the styles defined in the last-linked style sheet have precedence. Similarly, if you have these rules in<br />
a style sheet<br />
p { font-size: 10pt; color: red; }<br />
...<br />
p {font-size: 12pt; }<br />
then your paragraph text will be 12pt and red.<br />
