HTML Reference

Use the HTML reference guides to quickly find information about HTML elements, attributes, entities, document structure, accessibility, browser support, character encoding, and other important web development topics.

Using the HTML Reference

The HTML Reference is designed to complement the HTML Tutorials. The tutorials explain HTML step by step, while the reference pages provide quick access to specific information when you need to look something up.

You do not need to memorize every HTML element, attribute, entity, or browser feature. Use these reference guides while learning HTML, writing webpages, maintaining existing websites, or checking markup you are unfamiliar with.

HTML Elements & Attributes

HTML elements define the structure and meaning of webpage content, while attributes provide additional information or modify how an element works. These references provide quick access to both.

HTML Attribute List Browse HTML attributes with descriptions and links to detailed attribute reference pages. Global Attribute List Find attributes that can be used with most HTML elements, including class, id, style, title, and data attributes.
