There is a div on his background image, then, to darken the picture, superimposed on the block, another block with the following class
.bg{ position: absolute; z-index: 15; width: 100%; min-height:200px; max-height:250px; background: #000; opacity: 0.5; } The problem is that it costs 100% width, but a gray strip appears (a piece of this block with class bg )
