Can you post the URL of your site please, so we can have a check. You can do that in a private reply if you like.
You can try yourself first to customize it, this article should assist: https://wpgeodirectory.com/docs/customizing-your-style/

Try something like this for fixed width of content:

#geodir-wrapper {
    margin: auto;
    max-width: 1200px;
}

or for fixed margin left and right

#geodir-wrapper {
    margin: 0 50px;
}

You’re welcome 🙂
