customify-grid has considerable padding on the right side

Is there any way to change this to where there won’t be this right side padding? I want the page content to have equal widths to the left and right. With the way customify-grid styles things, the content is far to the left of centered. I’m having trouble figuring this out because I’m not well versed on this level of CSS. I’m seeing the following:

[class*=customify-grid-], [class*=customify-grid_], [class~=customify-grid] {

1. box-sizing: border-box;
2. display: flex;
3. flex-flow: row wrap;
4. margin: 0 -1em;

}

But I’m not sure what to change here to get rid of this right side padding. Thanks for any assistance you can provide.
