Thank you! :D While there's still tweaks to be made to the header, here's a copy of what the CSS code is like as of now, with a few more comments than before - https://www.mediafire.com/file/fjsema7jr1u5yo1/dreamwidth_style_sheet_070723/file

If you've got a mid-level experience of CSS, it should be pretty easy to navigate. Happy to answer any q's~
