Describe the issue or the suggestion:

• CSS not optimising text for dark mode.
  

How would you fix the issue / which content would you add or delete?

• Make the CSS Property for the text to be white on dark mode like color: #ffffff; That's CSS, but I'm not sure how it's implemented on the website.
