Another little tip and trick – the old way of using the “name” HTML element is not supported in ePub… but you can just switch your targets to “id” tags instead.
<a href="webpage.html#partofpage">
This would take you directly to the middle of a web page (or ePub page). There was a target to tell where the link ended up – but that way’s changed. [h/t here for the solution…
OLD WAY:
<a name="partofpage"></a>
NEW WAY (What’s this about a new way?)
<a id="partofpage"></a>
