SPEAKER: The worldwide web is all about hyperlinks, or links. So let's write a web page that has a link. Here, in link.html, I've already written some HTML for the head, for the title, and for the beginning of the body. And I've also preemptively closed all those tags because, inside of the body here, I'm going to type something like, this is. And now I want to provide a link to CS50's website. But I want the word still to be CS50. I don't want to visually see www.cs50.net, or something along those lines. 

So let's do open bracket a, for anchor. Let's specify an attribute, so to speak, a piece of text that modifies the behavior of this tag, as href equals, quote, https://www.cs50.net/. 

Let's now close the quote. Let's now close the tag, and specify that the word I want the user to see is CS50. Let's now close the tag with open bracket, slash a, closed bracket. Complete my sentence. Save the file. 

Let's now change the permissions on this file and view it in a browser, chmod a plus r link.html. Let's now open up Chrome, visit http://localhost/link.html. There we have a link highlighted in blue by the browser by default. And indeed, if we hover over it here, notice in the browser's bottom, left-hand corner, we see the link to which we'll be redirected. And if I click, we'll find ourselves on CS50's web page.
