• href specifies the URL.
• title additional information (tooltip).
• target="_blank" opens the link in a new tab.

HTML5 Custom Data Attributes (data-*)

HTML5 introduced custom data attributes, which allow you to store extra information on standard, semantic HTML elements without other hacks like non-standard attributes or extra properties on DOM. They are named with prefix data-.

 

HTML

<div data-user-id="123" data-role="admin">Admin User</div>

 These attributes can be accessed in JavaScript using the dataset property.

Best Practices for Using HTML Attributes

1. Use Meaningful Values:

• Ensure the values of your attributes are meaningful and relevant to their purpose.

2. Keep IDs Unique:

• The id attribute should be unique within the HTML document to avoid conflicts.

3. Use Classes for Styling:

• Prefer using the class attribute for CSS styling rather than the style attribute for better maintainability.

4. Accessibility Considerations:

• Use attributes like alt, title, and aria-* to improve accessibility for users with disabilities.

5. Avoid Inline Styles:

• Inline styles (style attribute) should be used sparingly; external or internal CSS is preferred for easier management and separation of concerns.
