Hyperlinks have been around since the beginning of HTML4 and continue today. They are the bedrock of web pages as they take us places. They have a similar structure to image tags, and they look like this.
<a href="mypage.html">Link to somewhere</a>
The <a> tag is called the anchor tag. It tells us that there will be a link there. The href is the attribute that indicates where you are going to go. So in the previous instance, if we clicked on the Link to somewhere, it would take us to the mypage.html page.
So, how does the whole page look?
<html>
<title>My first page</title>
<body>
<a href="secondpage.html">Go to my other page</a>
</body>
</html>
Whereas on the second page, you might have something that looks like this.
<html>
<title>My second page</title>
<body>
<a href="firstpage.html">Go to my first page</a>
</body>
</html>
Keep in mind that you have to have two pages named secondpage.html and firstpage.html, respectively.
