What is CSS


Collapse Content

After learning the basics of HTML, it's time to learn the essentials of CSS!

Cascading Style Sheets (CSS) is a language used to specify the appearance of web pages. While HTML is used to mark the structure of a page, CSS is used to customize how the look and formatting of web pages.

For example HTML is used to mark parts of a page as a:

  • heading
  • paragraph
  • table
  • list

...while CSS is used to specify any HTML element's:

  • size
  • color
  • spacing

In the challenge below, you can see some HTML for the page and a simple paragraph and some CSS in between the <style> tags. Make a small change to the CSS to solve the challenge!

Challenge

Below there's some CSS that sets the color of the paragraph to red. Change the red to green.
