I actually didn't know about the TF2 S.T.A.R.S. browser extension, so thank you for the report and showing me something new. This should be fixed now! If you visit the style page at https://userstyles.org/styles/152997/logs-tf-dark-theme, you can update your copy of the style.

Unfortunately, I'm not sure why it wouldn't show up in your Stylish list. Out of curiosity, which browser are you using? The style seems to install correctly on Google Chrome and Firefox Nightly for me.

In response to your question, I just made a quick dark theme for logs.tf. Feel free to let me know of any issues or potential improvements in this thread, even if they're nitpicky. I hope this helps!
