link not working

I am trying to create a set of links to specific sections in the page using the <a href="#..."> notation, but it doesn’t seem to work. Clicking on the link seems to do nothing and right-click -> open in a new tab changes the url but does not move to a different section of the page. I am using Firefox 28.0. My links are as follows:

<div>
    <p>Contents</p>
    <ul>
        <li><a href="#map">Map</a></li>
        <li><a href="#timing">Timing</a></li>
        <li><a href="#timingdetails">Timing Details</a></li>
    </ul>
</div>

And they should be linking to:

<div id="map">[content]</div>
<div id="timing">[content]</div>
<div id="timingdetails">[content]</div>

Links to external webpages work fine. Placing the id="..." feature inside an <a> tag instead did not fix the problem. My webpage url is of the form http://127.0.0.1/foo/bar/baz/. This is within a Python Django project.

Any idea why this isn’t working?
