3. Place that complete opening <a> tag from above before the text or object you want to link to, and add a closing </a> tag after.
Doing this sets the location of the link. This is what your code should look like now:
<a id="INSERT_YOUR_OBJECT_NAME_HERE">The object you want to link to.</a>
<a id="facebook_ads_example">This is the Facebook ad example I want to link to.</a>
4. Create the hyperlink that'll take you to that text or object.
Now, go to the part of the post you'd like to have the hyperlink in. You'll need to add a typical hyperlink HTML markup, but in the part where you'd typically include a URL, you'll include the pound symbol (#) then the name of the object you're linking to. Here's what it looks like:
<a href="#INSERT_YOUR_OBJECT_NAME_HERE">Click here to see the content below.</a>
<a href="#facebook_ads_example">Click here to see an example of how a company uses Facebook ads.</a>
And then you're all set — you have a functioning hyperlink between two pieces of content on the same page. Simple as that.
