HTML Tag

Definition and Usage

The <a> tag defines a hyperlink, which is used to link from one page to another.

The most important attribute of the <a> element is the href attribute, which indicates the link’s destination.

By default, links will appear as follows in all browsers:

  • An unvisited link is underlined and blue
  • A visited link is underlined and purple
  • An active link is underlined and red

Tips and Notes

Tip: If the <a> tag has no href attribute, it is only a placeholder for a hyperlink.

Tip: The following attributes: download, hreflang, media, rel, target, and type cannot be present if the href attribute is not present.

Tip: A linked page is normally displayed in the current browser window, unless you specify another target.

Tip: Use CSS to style links: CSS Links and CSS Buttons.
