It ought to be a rather easy question. My website does what I say:
#landing-wrapper {
display:table;
width:100%;
background:url('landingpagepic.jpg');
background-position:center top;
height:350px;
}
I want to make the backdrop picture darker. I don't believe I can actually add another div above it to darken it because this DIV has UI components. Suggestions?
