If i upload 980x120banner, its shows only desktop. There are option to upload smaller versions for tablets and mobile. What are max-width size for those banners?

Btw, why we dont use img {max-width:100%} for these banners, so you could use same banner for every device?

Could you please provide a little more background on what you're doing? Is this in the advertisements? Ensure you uploaded sizes for tablet and mobile by clicking "Upload smaller versions?" button and uploading in provided areas.

Yes, advertisemets. But what are banner sizes for tablets and mobile?
