1. Definition and Usage

The <a> tag defines an anchor. An anchor can be used in two ways:

  1. To create a link to another document, by using the href attribute
  2. To create a bookmark inside a document, by using the name attribute

The <a> element is usually referred to as a link or a hyperlink.

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

2. Tips and Notes

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.
