A Beginner's Guide to HTML

If you're new to web development, you're in the right place! HTML (HyperText Markup Language) is the backbone of every website. It's the standard language used to create and structure the content of a web page, from paragraphs and headings to images and data tables.

HTML works using elements, which are represented by tags. For example, to create a paragraph, you would wrap your text in a paragraph tag:

This is a paragraph.

. This HTML Viewer is the perfect playground to experiment with different tags and see their effect immediately.
