HTML stands for \u201eHypertext Markup Language\u201c and is the fundamental markup language of the World Wide Web. It is used to define the structure and content of websites. Unlike a programming language, HTML does not perform any logical operations, but describes how text, images, videos, hyperlinks and other media elements should be arranged and displayed on a website.

Some elements, such as <img><\/code> for pictures or <br><\/code> for line breaks, are \u201eself-closing tags\u201c and do not require a separate end tag.<\/p>\n

An example of this is the src<\/code>-attribute for images (<img src="bild.jpg" alt="Description"><\/code>), which specifies the path to the image file, or the href<\/code>-attribute for Links<\/a> (<a href="https:\/\/www.beispiel.de"><\/code>).<\/p>\n
