I add

h1 {
    margin-top:100px;
}

to the end of the css, but the page doesn't change. But if I add to the html of some h1:

<h1 style="margin-top:100px;"><a class="toc-backref" href="#id4">KHotKeys</a><a class="headerlink" href="#khotkeys" title="Permalink to this headline">¶</a></h1>

Then it does.

I'm not css pro, and I guess the problem is somewhere in the css file. Here it is:

div.clearer {
    clear: both;
}
