@cycle-space Hi, the screenshot of the monthly summary is below

The CSS works fine in my Obsidian, with Toggl Track v0.11.0.

To have a quick check in your Obsidian, you can create a new vault and add the snippet to have a test. btw, don't forget to enable this CSS snippet. :)

Thanks a lot for your help, it works! And thanks for your nice work again!
