<a>

HTML <a> Tag

The <a> tag is used to insert hyperlinks to other pages, or files, locations within the same page, email addresses, or any different URL. You can use both text and image as a hyperlink.

In the browser, hyperlinks differ in their appearance and color. By default, HTML links appear as underlined blue text. When you hover your mouse over a link, it turns red (active link). Links that are already clicked (visited links) become purple.

You can change the color of links, remove underline or change the color of the links using CSS styles.

The “download”, “media”, “hreflang”, “target”, “rel”, and “type” attributes will be present only if the “href” attribute is present.

Until you define another target, a linked page is shown in the current browser window.

The <a> tag can have attributes that provide additional information about it.

The href attribute

The href is a required attribute of the <a> tag. It defines a link on the web page or a place on the same web page, where the user navigates after having clicked on the link. The value of the attribute is either an anchor or a URL. The anchor points to the ID (unique identifier) of the part of the web page referenced. Before the ID we put a hash (#).

It looks like this:

<a href="url">the link text</a>

<a href="#a">the link text</a>

Example of the HTML <a> tag with the href attribute:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
  </head>
  <body>
    <a href="https://www.w3cdoc.com/">w3cdoc.com</a>
  </body>
</html>

Result

w3cdoc.com

Click on the link, and you will be redirected to the home page of our website.

Using the href attribute of the <a> tag with the <img> tag you can make a linked image.

Example of the HTML <a> tag for creating a linked image:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
    <style>
      img {
        height: 90vh;
      }
    </style>
  </head>
  <body>
    <a href="https://en.wikipedia.org/wiki/France">

    </a>
  </body>
</html>

The target attribute

The target attribute

The target attribute is used to tell the browser where to open the document (by default, links open in the current window).

The target attribute can have the following values:

  • _blank– opens the link in a new window.

  • _self-opens the link in a current window.

  • _parent - opens the document in the parent frame.

  • _top - opens the document in full width of the window.

Example of the HTML <a> tag with the target attribute:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
  </head>
  <body>
    <a href="https://www.w3cdoc.com/" target="_blank">w3cdoc.com</a>
  </body>
</html>

Result

w3cdoc.com

The rel attribute

The rel attribute

This attribute sets the relationship of the current document to the linked one. The attribute values can be as follows:

  • alternate - an alternative version of the document.

  • author- reference to the author of the document or article.

  • bookmark - a permanent link to be used for bookmarks.

  • nofollow - links to an unendorsed document (this instructs the search engines that the crawler should not follow that link).

No follow value

If you want to create a nofollow link, use rel=“nofollow”. This informs search engines that you don’t support the content at the other end of the link. The nofollow attribute value is generally used on paid links and advertising. Sometimes the unfollow is considered to be a tag or attribute, but in fact, it’s a value of the rel attribute.

Example of the rel attribute with the “nofollow” value:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
  </head>
  <body>
    <p>Lorem ipsum, or lipsum as it is sometimes known, is dummy text used in laying out print, graphic or web designs. The passage is attributed to an unknown typesetter in the 15th century who is thought to have scrambled parts of Cicero's De Finibus Bonorum et Malorum for use in a type specimen book.</p>
    <p>This text is from <a href="https://www.lipsum.com/" rel="nofollow" target="_blank">Lorem Ipsum</a>.</p>
  </body>
</html>
