HTML and CSS are the building blocks of the web. In this tutorial, we will be covering the basics of HTML and CSS.

HTML

HTML is the language used to create web pages. HTML stands for HyperText Markup Language. HTML is a markup language, which means that it uses tags to identify different elements on a web page.

Tags are surrounded by angle brackets, like this:

Tags can be either open or closed. An open tag is the tag that starts the element, and a closed tag is the tag that ends the element. For example, the tag is the open tag, and the tag is the closed tag.

HTML tags are not case-sensitive, so you can use uppercase or lowercase letters.

Here is a simple HTML document:

Hello, world!

This document has three tags: , , and . The tag is the document type declaration, and it tells the browser which version of HTML the document is written in. The tag is the root element of the document, and everything else is nested inside it. The tag is the main content of the document.

HTML tags are usually paired. The opening tag is always followed by a closing tag, and the closing tag is always preceded by a forward slash. For example, the

tag is always followed by a

tag, and the

tag is always followed by a

tag.

CSS

CSS is the language used to style web pages. CSS stands for Cascading Style Sheets. CSS is used to style all of the HTML tags on a web page, including the text, fonts, colors, and layout.

CSS is not required to create a web page, but it is recommended. CSS is a separate file that is linked to your HTML document.

Here is a simple CSS document:

h1 {

font-size: 24px;
