Image/ text link linking to internal links

I’m not sure how to include an Image/text link in the services pages of my website. If you check out https://williamfraser.com/ you’ll see there are sections on his page with icons for their services (web design, graphic design etc) with short descriptions of the service underneath and a link to “Learn More”. Are there any tutorials where I can learn how to do this? Or is there any certain plugin I can use to create these? Thanks
