Change font size of lists

Hi,

I’m struggling with a smaller font size for both ordonated and unordonated lists. This is the custom CSS I have on the website:

p, ul, ol {
font-size:18px;
}

.single .entry-title {
font-size: 30px;
}
.entry-content {
font-size: 18px;
}
.entry-title {
font-size: 30px;
}

Any idea what might make it work?

Thanks,
Raluca
