Returns the bit depth of the screen. Per CSSOM View, the value is always 24, for compatibility reasons.

Syntax

depth = window.screen.pixelDepth

Example

// if there is not adequate bit depth
// choose a simpler color
if ( window.screen.pixelDepth > 8 ) {
  document.style.color = "#FAEBD7";
} else {
  document.style.color = "#FFFFFF";
}
