Change max width and gutter size of single screen

I have an application that uses an external theme which I can not change. This theme is fine, but I would like to use another self made screen layout for one specific page. This would have a much smaller gutter size and higher max width.

However, I am not able to find where I need to change the gutter size and max width of one specific screen.

How can I achieve this?

Hi Tom,

Could you not add custom css to the specific screen such as the code below or play around with the .layout .main-content.ThemeGrid_Container CSS?

html {
    max-width: 1280px;
}

Another options would be to create a new theme and apply it to a UIFlow and put that specific screen under that flow.

Regards,

Melissa

Creating a new theme and put the specific screen in a seperate UIFlow made it work.
Thanks!
