HTML stands for hypertext markup language.

Hypertext is text with links that readers can simply click on to go to another page or another part of the page. Meanwhile, markup language uses tags or plain text with special markings to define the sections of a page, such as headers and footers, and other elements, including tables and images.

To write HTML, you'll need a text editor, like Notepad, Brackets, or Atom. HTML editors make sure your coding is clean and functional. They help reduce errors by automatically inserting tags (auto-completion) and other common elements or through debugging.
