HTML stands for HyperText Markup Language. Used by most web pages, it is the programming that translates coded formats into the images that you see. It serves numerous purposes, embedding videos and images and scripts and structuring a page’s content. To encode text inside emails or web pages, designers use HTML elements called tags. These tags are enclosed inside brackets. For instance,

<h1>is the start tag for a large header font. At the end of the header is placed an end tag, which includes a forward slash</h1>
