Responsive development for on desktops

I have written the media queries for all desktop breakpoints. I developed for large screens first them worked down adding breakpoints. I tested for the most popular screen sizes:

1920×1080, 1536×864, 1440×900, 1366×768, 1280×720

However, not all needed their own breakpoints so I used these breakpoints:

1530px, 1430px, 1340px

Next up tablet and mobile...
