If you wish to apply Dark Mode to our Toomics platform either through your PC or through a web browser on your mobile phone, we recommend you to use Chrome as your default browser and download the Dark Mode extension on the Chrome Web Store.
Please click the following link to access all the different extensions provided by Chrome and you will be able to find the Dark Mode: https://chromewebstore.google.com/?hl=en
However, please note that we are working to integrate our whole website to the dark mode, the same way we are offering it on the application.
