Mimimal transparent GUI

Original: This is the first thing I've made on this website. I liked using transparent packs but couldn't find one that I really wanted so I just made my own and decided I'd share it here. There wasn't one for 1.14 either so I thought I'd try to be the first. It's really simple with a gray border and everything else is transparent. Should work with previous versions too.
Comment anything you would like to see changed and I'll probably do it.
Thanks for looking :D

Update: Works with 1.14 through 1.18 now. Tweaked a few little things to make it more uniform. If you have optifine the start-up screen will be gray to match. Sorry if the pictures are a little messy, just wanted to give as much info about it as possible but I have no artistic talent.
