We have a number of marketing forms that we've created and added to marketing pages. Currently the entire page is white and this looks very poor on modern wide monitors.
What i'd like to do is keep the background colour of the form and column white, but change the background colour of the rest of the page to be a light grey. I've tried adding some code snippets (eg style=/background-color:#e8e8e8/) but i'm not sure if it's the way D365 pages are setup or my basic html skills but i only ever seem able to change the colour of the margin/padding around the form rather than the entirety of the background of the page.
