Scroll cursor over images to see text

Hello everyone!

I am very new to all this so any help would be great. 

I am wanting to make my services section in the form of a gallery, so I would like you to see text about each category when you move your cursor over each image. How would I do this? I'm very green when it comes to code also. 

Thank you so much team!

You can use Inline Image Block or Poster Block to achieve this

But when you add a section, you need to choose Classic

Then you can add Image Block, and when edit Image Block, you will see some options to change it to Inline, Stacked, Collage or Poster

Another way is add Gallery Block, add gallery caption, then we can help with some lines of code to make text appear on hover image
