How to reduce the bar/message height/thickness

Hello, I was using an old version of the plugin in a previous website and the height of the bar / header / message / “however you wanna call it” of the cookie consent was OK, but I’m using it in a new website (I can’t tell you the URL because it’s closed with password, sorry for that) with the newest version, and the bar is too thick, actually there’s space to almost fit the text 5 times, you can check it here: https://imgur.com/a/WuE9anP so could you please tell me how to make it smaller? As in less thick. Thanks a lot!
