Improving Dark Mode Toggle

[louisefindlay23]

Improve the current dark mode toggle. Currently, the toggle is at the left hand side with no space between it and the edge of the browser. There's also large text that's says enable Dark Mode.

• The toggle could be moved to the the top left similar to the navigation bar

• The toggle switch could be modified to a sun and moon icon similar to this article - there's a Github repo and Codepen inside

@dtemir, would you be interested in working on this since you helped make the dark mode?

[dtemir]

@louisefindlay23 certainly!

@louisefindlay23 I would also love to join this one since we discussed this in our one-on-one. @dtemir If there's already a lot of progress here, then I will find another issue to work on.
