HTML stands for HyperText Markup Language. HTML is used by web browers for displaying information in the form of web pages. The purpose of a web browser is to display HTML documents. HTML is comprised of HTML elements. The HTML tags are combined with images, video, interactive forms and text to make up the web pages you see in web browsers. The web browser uses the HTML tags to format the web page content of the page, but does not display the HTML tags. Web browsers often have developer tools that allow you to inspect the HTML in a web page for investigating errors.
HTML elements are expressed as tags enclosed in angle brackets. HTML tags most commonly come in pairs like the html, head, title and body tags. The first tag in a pair is the start tag, the second tag is the end tag. You can also call them opening tags and closing tags or beginning and ending tags. Paired tags can contain other html tags. Most paired tags can also include text content.
