How to change the width of modals to a specific % based on page width?

Hi Wapplers

I am trying to work out how to adjust the size of the Modal element so that it maintains a specific % width based on the size of the browser window.

I want more control over the modal width than is currently available out of the Wappler box.

I have had a look and tried different approaches but I assume that it’s not as hard as I am making it out to be.

Any help would be appreciated!

Thank you!
