Toggle light mode

Here's a list of thing that i want to achieve.

  1. Do a better job at writing only on html so people who look at my site without all the styling and flashy stuff enabled could still enjoy reading it.
  2. Make a modern-ish look with only using CSS. (This probably will be the hardest challenge for me since i'm just starting learning html)
  3. Make a better dark mode switcher (this could be achieved by providing a copy of every .css and .html file and modify it to show different look. or i could use javascript which is the last resort)
  4. Make a dropdown menu for navigating purpose

I'll add something new to achieve while i get ahold of the basic concepts
