I have a problem with the banner. I've already seen the same issue in comments here but didn't find the solution. So here is the problem: when the window is small, in size close to a tablet screen, the banner looks ok. But when I do it wider, in a full screen — it looks terrible. I made a 3200x320 image, but it crops automatically in a strange resolution when I try to upload it. And the quality is much worse than on your presentation. So I made 3200x590 files. That helped me to fix the width issue a bit. But the quality of the image still looks awful on desktop. It's blurred somewhere and pixelized. I made both 72 DPI and 300DPI, no difference at all. What can I do with it?
