Description
Textual comments in CSS style sheets are similar to those in the C programming language.
body {
font-size: 62.5% /* 1em = 10px */
}
The stuff inside the/* */ marks are CSS comments.
Embedded styles are placed within the head element and use the style element. Embedded styles affect every instance of the element specified.
Inline styles, as you may have guessed, are placed inside elements within the body of an HTML document. Using the attribute "style", any element can be affected.
A style sheet gives the user several benefits:
- better control over layout.
- better control over text display.
- seperate form from structure.
- better site maintainability.
- smaller Web pages which means faster downloads.
CSS has the ability to explicitly control the status of underlining for an element - even for hyperlinks.
The id selector is used to specify a style for a single, unique element. The id selector uses the id attribute of the HTML element, and is defined with a "#".
