I use a website, which shows information i have no use for, so i tried to hide some of it with Stylish, an addon for Chrome to insert custom CSS.

I will try to explain better.

```
<div class="splitscreenleft"> <div id="toplevel"

<div class="splitscreenleft"> <div id="coursesection"

```

I want to hide one of those. Everything above splitscreenleft is the same on both. So the only difference is the div id below.

I must somehow hide one of the two classes based on the name of the div below it i think.
Any solutions to this problem?
