I'm making a website for a student organization at school and I need some help adjusting the header dimensions where the logo and main tabs are. I don't really know CSS or HTML, but am in the process of learning it -- just going at a slow pace lol I would like to change the vertical dimension of the white area where the logo is located (I believe it is the <div id="header">). It is currently at 163px and I'd like to make it smaller. The theme says that I can use the custom CSS area in the backend to make small adjustments, but I am unsure on how to type it out. I hope my explanation made sense on what I'm looking for, if not, please let me know and I will clarify it! Thank you!
