I have a simple one page website at that has three bugs: 1) The footer's color is not working. The CSS attempts to set the footer color, but it shows up as white all the time. Could be a html tag issue or a css issue. 2) The Dark Mode / Light Mode selector in the footer mostly works, but the CSS based animation of the toggle switch no longer works. This stopped working the same time bug number one appeared, so they are probably the same bug. 3) Clicking the Dark Mode / Light Mode selector does not always update the cat gif image. Sometimes it works, sometimes it doesn't work. Probably a JS issue. I would like to get these three bugs fixed now. Please only bid if you can fix these right now.
