Right size of Category banner image
Hi,
I'm adding a default Category banner image to each category of my website.
I noticed that for the 1st banner image added, this image is OK on desktop, but KO on mobile (size : 1440 x 340) : It remains dark grey.
So : what is the best (or minimum : size, or ratio) to use to fit on every screen ?
In the same way, I'd like to add a mention to my users for their "Cover image" (banner image in Profile page). Is it exactly the same expected size than for the Category banner ?
Thank you,
Regards,
Laurent
