I need help to change a class

I’ve just come back to Blocs after not amending my website for some time, and am somewhat rusty…

My website needs a bit of tweaking, but I cannot work out how to do it.

Basically, the homepage has 13 large images on it, all handled by a class called place-bloc as follows:

What I want is for the images to appear full-width at every viewport on every device, and for the height to be in proportion - the images are 1200 x 700 pixels.

I’ve fiddled with the settings in the screenshot, using %, vh, vw etc, but cannot get it to work.

I’d really appreciate some help please!

Fixed, ChatGTP rocks!

… and? What did it say?

That’s great, what did ChatGPT say?
