The header and footer I am using for my confluence site make some significant changes to the visual user interface to make the website more comfortable to members of the public who may not have used the confluence ui before, and are not members of our organisation.
Some of these changes affect the styling of the confluence side bar, which works fine once the website is completely loaded however before the header and footer are loading there is a brief flicker in which the orginal user interface can be seen, which doesnt look great.
I am wondering if there is a good way of fixing this issue within confluence cloud, I went looking for a way to edit the sites actual css but it seems this feature has been disabled (probably to stop people like me doing this).
