All solutions

What I would most like to check is if there is something simpler with just HTML and css to be able to work with different images in responsive mode, in this case I used a div and the backgroud-image property, but I didn't find any better method just with HTML and css.

The biggest and worst difficulty was making the layout responsive for mobile, where there were several selectors that needed to be modified, I wanted to check with everyone if it is possible to modify this in a more practical way, so that when working in a responsive way, many adjustments are not necessary in CSS components and selectors.

1. For me the most difficult thing for now is being able to adjust the block sizes so that it is the correct size and responsive.

2. My biggest doubt is which techniques to use to be able to adjust the size of images and components in the most fluid way possible.
