External CSS

An external style sheet is used to define the style for many HTML pages.

To use an external style sheet, add a link to it in the section of each HTML page:

Example

<!DOCTYPE html><html><head>
  <link rel=»stylesheet» href=»styles.css»>
</head><body><h1>This is a heading</h1><p>This is a paragraph.</p></body></html>

The external style sheet can be written in any text editor. The file must not contain any
HTML code, and must be saved with a .css extension.

Here is what the «styles.css» file looks like:

«styles.css»:

body {  background-color: powderblue;}h1 {  color: blue;}p {  color: red;}

Tip: With an external style sheet, you can change the look of an entire web site, by changing one file!

Attribute Values

Value Description
alternate Provides a link to an alternate version of the document (i.e. print page, translated or mirror).
Example: <link rel=»alternate» type=»application/atom+xml» title=»W3Schools News» href=»/blog/news/atom»>
author Provides a link to the author of the document
dns-prefetch Specifies that the browser should preemptively perform DNS resolution for the target resource’s origin
help Provides a link to a help document. Example: <link rel=»help» href=»/help/»>
icon Imports an icon to represent the document.Example: <link rel=»icon» href=»/favicon.ico» type=»image/x-icon»>
license Provides a link to copyright information for the document
next Provides a link to the next document in the series
pingback Provides the address of the pingback server that handles pingbacks to the current document
preconnect Specifies that the browser should preemptively connect to the target resource’s origin.
prefetch Specifies that the browser should preemptively fetch and cache the target resource as it is likely to be required for a follow-up navigation
preload Specifies that the browser agent must preemptively fetch and cache the target resource for current navigation according to the destination given by the «as» attribute (and the priority associated with that destination).
prerender Specifies that the browser should pre-render (load) the specified
webpage in the background. So, if the user navigates to this page, it speeds
up the page load (because the page is already loaded). Warning!
This wastes the user’s bandwidth! Only use prerender if you are absolutely sure
that the webpage is required at some point in the user’s journey
prev Indicates that the document is a part of a series, and that the previous document in the series is the referenced document
search Provides a link to a resource that can be used to search through the current document and its related pages.
stylesheet Imports a style sheet

What is CSS?

Cascading Style Sheets (CSS) is used to format the layout of a webpage.

With CSS, you can control the color, font, the size of text, the spacing
between
elements, how elements are positioned and laid out, what background
images or background colors are to be used, different displays for different devices
and screen sizes, and much more!

Tip: The word cascading means that a style
applied to a parent element will also apply to all children elements within the
parent
. So, if you set the color of the body text to «blue», all headings,
paragraphs, and other text elements within the body will also get the same color (unless you specify
something else)!
