RE: Conditional themes?

[Gerard Butler]

You can make your theme dynamic by using percentages in your theme.txt (so then when you change the values in grub.cfg to a different resolution the theme file will work just fine). However when grub stretches certain images it can make the appearance a bit unsightly. Over the past year of working with grub themes (I've made 18 in total) I found a couple methods to over come this. You could make a theme for every resolution, which I don't recommend because it is a lot more work. The other way is to stick to using elements that won't look bad after being stretched such as solid colored elements, or simple gradients.
