I have panel which I colored blue if this panel is being selected (clicked on it). Additionally, I add a small sign (
.png image) to that panel, which indicates that the selected panel has been already selected before.
So if the user sees for example 10 panels and 4 of them have this small sign, he knows that he has already clicked on those panels before. This work fine so far. The problem is now that I can't display the small sign and make the panel blue at the same time.
I set the panel to blue with the css
background: #6DB3F2; and the background image with
background-image: url('images/checked.png'). But it seems that the background color is above the image so you cannot see the sign.
Is it therefore possible to set
z-indexes for the background color and the background image?
