Font Size and custom CSS color

Hi,

Me again.

I’m also having problems with the font size not updating throughout the site when I change the slider.

I’ve also tried to use custom css to change the link a value to something other than the default (light yellow) which makes the link hard to read on a white background.

a {
color: #000000;
}

Again, the site is http://www.ourpottytrainingtips.com/25-potty-training-tips/

Thanks again.
Tom
