Hi Chris,
Thanks for reaching out.
You need to set the Site Width value to 100% and Site Width Max value to 1800px and also replace your code with the following custom CSS code to set the container full width. You may need to adjust the padding to align the content properly.
.x-container.offset
{
margin: 0 auto !important;
background-color: #20242d !important;
}
Please remember that the above code will work if copied as it is and doesn’t conflict with any existing style.
Please note that the code provided serves only as a guide to help you get started custom coding on your own if there’s no option offered in our theme or the products we bundle.
We really do not provide support for custom codes which means we can’t fix it in case it conflicts with something on your site nor will we enhance it. Further customization should be directed to a third-party developer or you can avail of One, where we answer the questions beyond normal theme support.
Thanks
