How do I add margins/change image width on my Impulse theme site?

Hello,

About a year ago, I upgraded my site to use the Impulse Theme. We have made some changes to the code along the way, but have always wanted it to have margins on the whole site (except the header and footer). We have read article after article and everything we try isn’t working.

We want to implement these changes on desktop/laptop only, because we have found that images that span the entire width become so large that it takes up the entire screen, and ultimately is not optimized for our customers.

I have attached a few screenshots of our current website, as well as a few of an example of what we would like to achieve.

Here Is a link to our site as well.
