Why is bgcolor not shared with bgimage?

Question

Sass

Tell. Why doesn't shading work on the picture?

#header
  height: 100%
  width: 100%
  position: absolute
  display: table
  z-index: 1
  background: url(../img/header-bg.jpg) rgba(0,0,0,0.6)
  background-size: cover

Answer 1

rgba(0,0,0,0.6) - here the fourth parameter adjusts the alpha channel for the color (black in this case). Your image is overlaid on a black background. And there already adjust, do not adjust the transparency for the color because of the picture you will not see anything. To darken the background image, use the second semi-transparent image.
