title_body: Does .epub support inline links? I want to better understand what options the .epub format have to provide more dynamic experiences than just reading a text linearly. 
  
  Is there a way to have links inside an ePub that point to another location in that ePub?
upvoted_answer: Yes, you can do that, .epub books are basically made of HTML and CSS, so if you have knowledge of these languages, in theory you can manually build an .epub from scratch (but the norm is to use specific GUI editors, that help you with this and many other tasks).
  
  Anyway, like I said, it is just HTML, so you just need to set ID's and anchors:
  
  
    Example  
    
    First, create a bookmark with the id attribute:
    
    &lt;h2 id="C4"&gt;Chapter 4&lt;/h2&gt;
    
    Then, add a link to the bookmark ("Jump to Chapter 4"), from within the same page:
    
    &lt;a href="#C4"&gt;Jump to Chapter 4&lt;/a&gt;
    
    Or, add a link to the bookmark ("Jump to Chapter 4"), from another page:
    
    &lt;a href="html_demo.html#C4"&gt;Jump to Chapter 4&lt;/a&gt;
