The table of contents on worg is shown/hidden using the :hover pseudo-element on the #table-of-contents element.
The problem is that this doesn't work on an ipad (or other touch device). The following javascript snippet will add a function to show the toc when it is "clicked", but I'm not sure where to put it (at the bottom of "preamble.html"?) #+BEGIN_SRC javascript document.addEventListener('DOMContentLoaded',function() { document.getElementById("table-of-contents").onclick = function() { var elem = document.getElementById("text-table-of-contents"); elem.style.display = elem.style.display == "block" ? "none" : "block"; } }); #+END_SRC rick
