Vantage Theme Unsightly Category Page Title

Hi,

I was just wondering if there is a simple way to remove the ugly category page titles such as the one I currently have – “Category Archives: blog” – not really sure why that shows up by default, maybe it is a something that is necessary when writing the code, but not being very clued up about coding I just see it as unnecessary.

Anyway, other themes I use just require some simple CSS code to be inserted and voila, no more silly heading.
}

.category .postsby {
display: none;

I tried this in the Custom CSS in Vantage, but it does not seem to do the trick. Is there some other way to get around this?

Thanks,

Chris
