HTML (Hypertext Markup Language) and CSS (Cascading Style Sheets) are the two fundamental technologies that power the modern web. Together, they form the foundation of nearly every website and web application, and are essential skills for any web developer to master.
HTML is used to structure and organize content on the web, while CSS is used to control the appearance and formatting of that content. With HTML, you can define the structure of a webpage by marking up text, images, and other content with tags. CSS, on the other hand, allows you to style and layout your content by specifying colors, fonts, sizes, and other visual properties.
One of the key benefits of using HTML and CSS is that they are separate technologies, which means that you can change the appearance of your website without altering its underlying structure. This makes it easier to update and maintain your website over time, as you can make visual changes without having to re-write the underlying HTML code.
Let’s take a closer look at how these two technologies work together to create beautiful and functional websites.
HTML is a markup language that is used to structure and organize content on the web. It consists of a series of tags that are used to mark up text, images, and other content in a way that is readable by both humans and computers.
Here’s a simple example of an HTML page:

<h1>), a paragraph element (
<p>), and an unordered list element (
HTML tags are usually written in pairs, with an opening tag and a closing tag. The closing tag is the same as the opening tag, but with a forward slash (/) before the tag name. For example, the opening and closing tags for a paragraph element are
CSS is a style sheet language that is used to control the appearance and formatting of HTML content. It allows you to specify visual properties such as colors, fonts, sizes, and layout for your webpage.
Here’s an example of some CSS code that could be used to style the HTML page we looked at above:
