CSS rules are made up of a selector and at least one declaration. A selector is the code that selects the HTML to which you want to apply the style rule. A declaration is made up of at least one CSS property and related property value. CSS properties define the style:
h1 {color: red;}
- Browser style This is the default style sheet within a browser. If you declare no style rules, these defaults are applied.
- User style A user can write a style sheet and make it override any styles you create by changing a setting in the browser.
- Inline style This is style that is used right in the individual element and applied via the style attribute.
- Embedded style This is style that controls one document and is placed inside the style element within the HTML document.
- Linked style This is a style sheet that is linked to an HTML document using the link element in the head of the document.
- Imported style This is similar to linked styles, but it enables you to import styles into a linked style sheet as well as directly into a document.
Inheritance
Inheritance means that styles are inherited from their parent elements. Consider the following:<body>
<h1>My header</h1>
<p>Subsequent Text</p>
</body>
