Adjusting the slider to display text more legibly

Hey Pinboardians,

I’ve just started using this theme on my new project and I’m loving it; I really enjoy the slider on my landing page, but I’m keen to make a small adjustment to it to make it a little easier to read and navigate.

Is it at all possible to adjust the slider via CSS so that it displays the text and navigation a little bolder, or can I adjust the level of transparency used underneath the text to make them stand out a bit more? Sorry, I’m a complete neophyte when it comes to these kinds of adjustments and I would rather now blow up the damned site in my lame attempts to figure it out myself.
