I am trying to fix a site written by someone else. Most things seem to work, except for the menus in responsive view. The "hamburger" button does appear, but it's not clickable. The CSS is kind of huge, and I don't quite know where to start.
This is what a see in responsive view under that button:
<button type="button" class="navbar-toggle"
data-toggle="collapse" data-target=".navbar-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
Where should that data-target lead?
Also, please let me know if I need to add the contents of the JavaScript files to JSFiddle as well. They didn't seem relevant to me.
