@beatrizb even if you make that change you will have a domino effect of other things that must be changed to support it without detrimentally affecting the masthead .
The notification bar will still be over the image or you have to make it transparent impacting text contrast.
The menu items have the same issue with navigation being even more critically impacted by bad contrast against a background image.
Any sticky menu feature would also likely need to be adjusted.
The banner text would need to try and be moved to avoid a crammed layout of everything squished towards the top of the page.
If you must have this customization for debut I can be hired at email@example.com
