Remove Links From Homepage Slider Images

The sliders are featured post sliders, and they are linking back to posts that have the featured images, and I don’t want them to link anywhere. I created those posts, just to make slides for the homepage- I don’t want any links on the slides. Is it possible to remove those links? Thank you for any assistance!

If I have to go in to CSS file and make changes, please can you confirm which CSS file this is please and whereabouts in the file?
