  Introduction to HTML and CSS

  Get started creating web pages with HTML and CSS, the basic building blocks of web development. HTML, or HyperText Markup Language, is a standard set of tags you will use to tell the web browser how the content of your web pages and applications are structured. Use CSS, or Cascading Style Sheets, to select HTML tags and tell the browser what your content should look like. Whether you are coding for fun or planning to start a career in web development, learning HTML and CSS is a great place to start.
