title: Switch between a normal "light" color scheme and dark night mode theme in Wordpress?
body: <p>I've been asked to implement a Day/Night mode in the page I'm maintaining.
  The idea is that the default theme is a light coloured theme with light background and darker fonts and pressing a button swithing to night mode and back.</p>
  
  <p>In a hand made site this looks easier by only switching between 2 .css files or overwritting colours with another one when required, at least that's how I think I would do it.</p>
  
  <p>But in wordpress I don't know what would be the best way to achieve this.
  I looked for a plugin that does this and inverts my styles colours in some way to create a dark mode but could not find anything like this.
  As I see I will have to do it myself manually, what would be the better logical way of achieving this?</p>
  
  <p>Just asking about the procedure and what files should I modify or touch.
  Should I create another style.css and change it? Would it affect only the user that is performing the change on his/her browser and not globally?</p>
