Sorry if it has been asked before but I googled it and didn't find a good answer.
In basic html you can link inside a document using the name attribute:
A named anchor inside an HTML document:
<a name="tips">Useful Tips Section</a>
Create a link to the "Useful Tips Section" inside the same document:
<a href="#tips">Visit the Useful Tips Section</a>
Or, create a link to the "Useful Tips Section" from another page:
Visit the Useful Tips Section</a>
Does this work in epubs and do ereaders support it?
