How to Work with Attributes in HTML

Tags often have attributes for further defining the element. In this how-to, you'll learn how to use attributes.

Attributes are name-value pairs that can be added to the starting tag in an element. For example, one of the most commonly used attributes is the id attribute, which looks like this:

<div id="mostImportantDiv"></div>

The HTML specification defines a set of global attributes that can be used with most HTML elements. The global attributes include the following:

  • accesskey
  • class
  • contenteditable
  • contextmenu
  • dir
  • draggable
  • dropzone
  • hidden
  • id
  • lang
  • spellcheck
  • style
  • tabindex
  • title
  • title
  • translate

Other attributes are specific to different groups of elements, or to just a single element. For example, the <img> element has a src attribute, which specifies the path to the image file.

Elements can have multiple attributes, separated by spaces, like so:

<tagname att1="value" att2="value">Element content</tagname>

The order of attributes is not important.
