HyperText Markup Language (HTML) is the language behind most web pages. The language is made up of elements that describe the structure of the content on a web page.
HTML is maintained by two separate groups: the World Wide Web Consortium (W3C) and WHATWG. See https://www.w3.org/html/ and https://html.spec.whatwg.org/ for the specifications.
In this lesson, we will look at the basics of HTML.
This lesson discusses how to properly mark up text. With just a few exceptions, it does not discuss how to change the formatting or display of these elements.
This is a task for CSS, which is not covered in this lesson.
The ability to link from one page to another is what makes HTML hyper. Calling it Hypertext, however, is a bit of a misnomer,
as images and other elements can also be linked.
Modern browsers generally support three types of images: GIFs, JPEGs, and PNGs. The PNG and GIF are generally used for simple images such as drawings;
whereas the JPEG format is used for more complicated images such as photographs.
You have already worked with div elements to break out a block of content. But the <div> tag doesn't tell us anything about the content it contains. In this lesson, you will learn about semantic (i.e., logical and meaningful) block-level elements.
