How do most of you program your back covers?
1. <p class = ... > statements that define it an image, OR
2. <div> <a id= ...> </a> <image src= ...></<div>
The problem I am having is getting the back cover to consistently center when I convert from epub to mobi in Calibre. It seems if I open the epub in Sigil, center the image (if it is programmed per "1." above), then converted that epub through Calibre I have better success. BUT, that's a lot of steps.
Any help for this rookie?
Thanks!
