CSS for the Monitor QHD

Media query by width

Breakpoints are written in CSS pixels, never in physical resolution.

/* Monitor QHD: maximized window, 2560 CSS px wide */
@media (max-width: 2560px) {
  /* … */
}

How Breakpane emulates the Monitor QHD

Breakpane opens the Monitor QHD as a 2560×1440 screen with the device's frame, density (1), the user agent of Chrome on Windows and the system bars, floating in front of your editor with your dev server live.
