Social media dashboard using Sass and grid

After doing some newbie level challenges, I decided to try one from Junior level. This is my first challenge using Sass and grid and I copied the javascript and the color variables from luisdev-works project because I saw he managed to change the background color in an easy way by simply changing the body class and not the rest of the divs. I think the switch button becomes bigger when it's on the right side and I am not sure how to fix it.
