How to stretch the image to the width of the block with the specified padding property?

Question

Bootstrap

The idea is to stretch the pictures in the body to the width of the block. Given the features of the CMS, you can change the parameters only through img.
I tried this, but the picture just sticks to the left side and that's it.

.img-fix img {display:block;width:100%;height:auto;margin:0px -64px !important;}

The parent container has card card-body and p-3. How to be?

A link to the page would help you more. And so you have to guess.

Although I'm not sure it will work. Doesn't CMS have the ability to add custom CSS? Here you need to work on the parent
