Hi @Derek_vdS excellent question! My pleasure to help in any way possible.
Yes the CSS would over-ride the width you set on an inline image property setting. Keep in mind that since the image is inside of a dynamic list, when you add that image width setting within the settings tab, you’re applying that width setting to all of your images in the dynamic list.
To help me further investigate (thank you again so much for your help) do you recall what setting you had on the image beforehand that was causing it to render so small and what change exactly that you made to resolve the rendering issue?
I’m trying to reproduce the behavior on this end to see if it was a bug or an issue with a certain style or style conflict instead.
Thanks in advance!
