Why is there a big white gap under my carousel on the homepage?
On most themes, the height of the carousel is determined by the tallest banner that you’ve uploaded. So if you upload two banners, one that is 2000×700 and one that is 2000×1500, the carousel height will be set to 1500px. This means that when the 2000×700 banner displays, there will be 800px of empty space below it.
To solve this problem, resize your carousel banners so they are all the same width and height, and then re-upload them. I recommend Canva for resizing and creating banners.
