Use all width Wexley template

Hello,

I've just redone my illustration site: www.faunesque.com
In the "INFO" page I'd like to change the layout and use the whole width to have something like this (see images) or like this :

Thank you very much for your help!

Add this to Custom CSS:

#collection-64832b85e9c3424db847c71f #page {
    max-width: 1400px;
    margin: 45px auto 0;
}

Adjust the max-width value to as wide as you want.

Remove the entire margin line if you want if left aligned.
