CSS stylesheet for improving the forums

I have written some CSS to improve the display of the new forums.
It is focused on better readability (font sizes and weights) and reducing wasted space.
It also includes indication of visited posts (gray text).

The stylesheet is free to use at your own risk, and you can edit it to taste.
Be aware that future updates of the forum software may lead to unexpected results when using injected css.

The Photoshop main page is coded differently than the other main pages, so there are some inconsistencies. The most important one being that the Photoshop main page will display "Welcome to the community" instead of "Photoshop ecosystem" at the top. All other main pages use the name of the application here.

To use, open the attached file (Adobe-forums.css) in a plain text editor.
If you have trouble opening it, change the extension from .css to .txt.
Then copy the contents of the file (not the file itself) into a CSS injector extension for your web browser.
I use the excellent User JavaScript and CSS extension from the Chrome web store.
It will work with Chromium based browsers, like Chrome, Vivaldi, Opera and Edge.
You have to give it permission to read and change data on websites.
CSS injector extensions are also available for other browsers.

I also recommend using the script by ​@johnrellis , which expands all nested replies, makes the reply box resizable, sets sort order to Oldest first, and adds the exact time and date of posts.
