Content off-center

https://856ltd.com/goe/services/

the content was being cut off regardless of what I did with CSS.
custom CSS is just:

#page_content_wrapper
{
width: 90%;
margin-left: auto;
margin-right: auto;
}
.wpb_single_image
{
max-width: 200px;
height: auto;
padding: 0 0 0 0 !important;
}

I decided to opt down to a max-width of 200px and made the headings h3 instead of h2. SO now it fits (sort of) but now the images are off center.

I feel like I’m toying with the wrong bit to make this work properly.
