Introduction to HTML Global Attributes

HTML Global Attributes are special attributes that can be used with all HTML elements, regardless of the tag type. Whether you are working with <div>, <p>, <input>, <section>, or any other element, global attributes remain universally applicable.

They help developers:

• Improve accessibility
• Control behavior and interaction
• Manage styling and identification
• Store custom data
• Enhance user experience, especially on mobile devices

Global attributes are defined by the HTML standard and are supported by all modern browsers.

What Are Global Attributes?

Global attributes are attributes that:

• Work with every HTML element
• Do not belong to a specific tag
• Provide common functionality such as identification, language definition, keyboard interaction, styling, and accessibility support

Example:

<p id="intro" class="text-primary" title="Introduction paragraph">
  Welcome to HTML Global Attributes
</p>

Here, id, class, and title are global attributes.
