I need a little help with my website's theme. Originally, it was translated over from what was essentially a dark theme but is now being used as a light theme. Because of that, there are still a few leftovers. Mainly, I need help changing the text colors to black on the Table of Contents, the blockquote, and the simple graph. As well as that, there seems to be a problem with the news blocks (I have no plans to use them, but still, I would appreciate it if someone can help me fix it.)
here is my theme testing page. Please help me out if you can.
