HTML5 Tag Cheat Sheet

HTML is the vital programming language of the Internet. But if you’re new to HTML, there’s quite a lot of stuff to remember — hundreds of tags all with their own attributes and a near-unlimited level of customization.

If you’re creating your first website — or if you just want to brush up on your coding — then this cheat sheet is for you! We’ve compiled all of the valid HTML5 tags, their functions, and whether they have SEO value so you can create and grow the website that you want.

To find the tags you need, just scroll through our list of tags. And if you don’t feel like working out your scrolling finger on your mouse, you can just type a query in the search bar!
