Introduction to CSS

CSS, or Cascading Style Sheets, is a stylesheet language used to describe the presentation of a document written in HTML or XML. In this guide, we'll provide an introduction to CSS and cover some of the basics of the language.

What is CSS?​

CSS is used to style web pages and other types of digital content. It allows developers to control the visual appearance of a document, including the layout, fonts, colors, and other aspects of design.

CSS works by associating rules with HTML elements. These rules specify how the element should be displayed, such as its size, color, and position on the page. When a web browser loads an HTML document, it also loads the associated CSS stylesheets and applies them to the document.

Setting Up a CSS Stylesheet​

To create a CSS stylesheet, you'll need a text editor and a web browser. Here's how you can set up a basic CSS stylesheet:

  1. Open a text editor such as Notepad or Sublime Text.
  2. Type the following code into the editor:
/* This is a comment */
body {
  background-color: white;
  color: black;
  font-family: Arial, sans-serif;
}

h1 {
  color: blue;
  font-size: 32px;
}

S3. ave the file with a .css extension, such as style.css. 4. Link the stylesheet to an HTML document by adding the following code to the head section of the HTML document:

<head>
  <link rel="stylesheet" type="text/css" href="style.css">
</head>

This CSS stylesheet contains two rules: one for the body element and one for the h1 element. The body rule sets the background color, text color, and font family for the entire page. The h1 rule sets the color and font size for all heading elements.
