Mobile image sizing?

Topic summary

A user is attempting to resize an image on their Shopify store to fill the entire mobile screen. Currently, when they resize the image, only the image itself changes rather than the entire section containing it. They want both the image and its section to expand to cover the full mobile viewport. A second participant responded indicating they found previous coding instructions confusing and difficult to follow, suggesting there may have been earlier troubleshooting attempts. The issue remains unresolved, with the user seeking clearer guidance on how to properly adjust the CSS or theme settings to achieve full-screen mobile image display.

Hey guys, I am trying to increase the entire size of this picture so it takes up an entire mobile screen. I have tried resizing the images though it just changes the image not the entire section. This is what it looks like at the moment on mobile though I want it to take up the entire screen including the section below it.

Sorry, I do not understand your coding and help. It is extremely confusing and so many mixed things to do. I struggle to understand all your explanations.
