Overlay Text OR Bold Post Title on Featured Slider in Catch Box Pro

Is there a way to edit the CSS to overlay the title text of the post in the featured slider OR bold it? I am using Catch Box Pro. Website is 72hrbugoutbag.com I just want for there to be a way for readers to know the post title WITH the pics. The post title is there now, but doesn't stand out at all. Any help with this will be greatly appreciated. Thanks!
