Listitems are acting really weird

Question

I have a website, http://www.veluwenkamp.nl On the home page at the bottom, you can find 4 listitems (pictures) They don't align very well, it has to be in one horizontal line.

I tried everything, but I can't make it work. Can you guys give me some advice?

Thanks in advance,

Answer 1

You can solve it by adding a clear: both to your ul

.lijstul {
    clear: both;
    ...
}
