Reduce spacing within (?) this image block

I'm trying to reduce the spacing/padding left and right within an image block. Also, to the right of the image is a text block.

Tried this code (without the X's) in Design > Custom CSS, but no go.

div#block-xxxxxxxxxxxxx
.image-block {
    padding: Xpx !important;
}

Feel as though I've searched for days! I'm missing something easy here, I know it.

Can you share your site with the protected password so we can take a look together?

I wish I could. Client will not allow it. ☹️ She's convinced it'll be a way to hack her site and info.

The extra mud-colored space on either side of the image is making me crazy. No idea even where to start. 

I'm a newbee, and have been fiddling with padding code, but nothing.

You can save (Ctrl S on Windows) current page >> The browser will download 1 file with name XXX.html + a folder. If you send someone these file + folder, we can view the current page from our pc without access your site.
