Troubleshooting z-index problem with background image and parent tag of image

I seem to be facing an issue with the z-index property. Here is the code snippet in question:

<div id="sidebarCont">
<div id="avatarCont" class="mask">
    <img id="" class="" src="img.jpg" alt=""/>
</div>

And here is the corresponding CSS:

#avatarCont{
overflow:hidden;
height:160px;
width:160px;
margin:0px auto;
background:url('../img/mask.png') no-repeat;
position:relative;
z-index:70;

}

#avatarCont img{
position:absolute;
top:0px;
left:0px;
z-index:50;

}

I am trying to apply a mask on the image, but I'm encountering difficulties. Any ideas on how to resolve this problem?

Answer №1

To achieve the desired effect, place the mask on top of the image by setting the image as the background of the outer container and the mask as the background of an inner container. The browser will display the outer container (the image) first and then overlay the inner container (the mask) on top. Unfortunately, if you are attempting to use alpha transparency, it is not supported by web technologies.

Here is the suggested structure:

<div class="image">
    <div class="mask"/>
</div>

Use the following CSS styles:

.image, .mask {
    height:160px;
    width:160px;
}

.image {
    margin:0px auto;
    position:relative;
    z-index:70;
}

.mask {
    background:url('img.jpg') no-repeat;
}

Answer №2

To create a mask after the container, you can utilize the :after pseudo element. Check out this example: http://example.com
