Links

Links are the foundation of the World Wide Web, and thus are an important component of most websites. Hyperlinking text enables users to move between the different webpages on your site (sometimes in the form of a menu or navigation bar), or connect to other resources or information on other websites.

The <a> tag, or anchor tag, creates a link to another document. You can use the <a> tag to link to other documents or webpages you created for the same site or to documents located elsewhere on the web. You can also use it to link to a particular location on a page - we’ll see an example of this in the section on classes and ids.

Relative links take the current page as an origin point and search for other files within the same folder or directory. This method is useful for creating links to pages within your own site.

The following appears as a link to the about.html page in the same folder as index.html:

<a href="about.html">About</a>

On your webpage it will appear as:

About

This link is asking the browser to look for a file titled about.html in the same folder. If a file named about.html is not in the same folder, clicking the link will result in a 404—Page Not Found error.

An absolute link includes information that allows the browser to find resources on other websites. This information includes the site domain—such as google.com—and often the protocol—such as http or https.

<a href="http://www.google.com">Google</a>

On your webpage it will appear as:

Google

This pathway is directing your browser to look online for this text document at the URL address provided.

Each example above includes an href tag. The href tag, short for hypertext reference, is an example of an attribute. Attributes offer secondary information about an element.

The <a> tag, or anchor tag, creates a link. The text within the <a> and </a> tags, the anchor text, is what a visitor to the site will see and can click on. The href= attribute tells the browser where the user should be directed when they click the link.

There is another technical difference between the two options above.

Use relative links when referring to pages on your own site. The main advantage of using relative links to pages on your site is that your site will not break if it is moved to a different folder or environment. (Not having to fix broken links one at a time will save hours of work!)

Activity

  1. Create a new text file called about.html in your htmlpractice folder. Copy over the HTML from your index.html file, but change the text in the <h1> element to “About.”
  2. In your index.html file, add a relative link leading to your About page.
  3. Also add a relative link from your About page to your index.html page. In this link, call your index.html page Home (Reminder: index.html is the default homepage)
  4. Lastly, include an absolute link to a page of your choosing. Remember that an absolute link includes the protocol (for example, http:) and also a domain (for example, cuny.edu): http://cuny.edu/about
  5. Re-save your text files and reopen or refresh them in your browser.

Check if it worked!

When your pages are updated, you should be able to navigate from your Home page to your About page, and vice versa. You should also be able to navigate to the external web page.
