Academy Website Dark Background

Hi, I am a new user and have started the Module training, I am really struggling with the white text on black background. The only way I can continue without eyestrain is to use the Accessibility settings on my Mac and Invert the display.
It would be fantastic for all Visually impaired users if they could change the background styling of the website with just one click in the user settings ( I believe this is relatively easy with CSS Styling?)

Thanks in advance…
