Adding Links
This section will teach you how to create a link to any web page. HTML uses tags to mark the start (<a>) and end (</a>) of the text that will be the clickable link. Therefore, the <a href=""> tag must be closed with </a> after your link text.
You will use three different attributes within your link. The three attributes that will be included in every link you create are href="" title="" and rel="". Each attribute adds a different meaning to the link as it is displayed on your online story page.
The following code…

…will look like this on your site:
Learn more about convergence at the William Allen White School of Journalism and Mass Communications.
The text in between the href quotes is the URL of the page you are linking to. This is the web page your browser will take you to when you click on the link. 
The text in between the title quotes will pop up when a user scrolls over your link. If you scroll over the convergence link above you will see the title text Convergence drives curriculum ” alt=”Title Explained” />
The text in between the the rel quotes labels the link as a link to an external web site as opposed to an internal link within your Online Portfolio. The rel attribute has no visual effect on your link. You will use it to differentiate between external and internal links. 
The text in between > and </a> is the text that will show up on your web page as the clickable link text.
