Opera browser fails to render CSS3 box shadow effect

My menu features CSS3 effects on hover and active states, giving it a unique appearance.

Below is the CSS3 styling I have implemented:

#Menu a:active,
#Menu a.active:before,#Menu a:hover:before
{
    Content: ' ';
    position:absolute;
    z-index:51;
    width:0px;
    height:0px;
    left:50%;
    top:50%;
    box-shadow:0 0 35px 30px #ADD7E7;
    -moz-box-shadow:0 0 35px 30px  #ADD7E7;
    -webkit-box-shadow:0 0 35px 30px  #ADD7E7;
    border-radius:50%;


}

While this styling works perfectly in Firefox and Chrome, I am facing compatibility issues with Opera. Any assistance in resolving this matter would be greatly appreciated. Thank you.

Answer №1

It appears that Opera requires the pseudo element to have a specified width and height, rather than being set to 0px. I recently tested the code below in Opera 11.62 and it seemed to function correctly.

#Menu a:active,
#Menu a.active:before,#Menu a:hover:before
{
    Content: '';
    position:absolute;
    z-index:51;
    width:1px;
    height:1px;
    left:50%;
    top:50%;
    background: #ADD7E7;
    box-shadow:0 0 35px 30px #ADD7E7;
    -moz-box-shadow:0 0 35px 30px  #ADD7E7;
    -o-box-shadow:0 0 35px 30px  #ADD7E7;
    border-radius:50%;
}

Answer №2

Here is a code snippet for creating a shadow effect:

HTML

<div class="shadow-bringer shadow"> HI ! Welcome. </div>

CSS

.shadow-bringer {
    background: none repeat scroll 0 0 #FFFFA2;
    height: 100px;
    margin: 20px auto;
    padding: 5px;
    width: 100px;
}
.shadow {
    box-shadow: 0 0 8px #CCCCCC;
    -moz-box-shadow: 0px 0px 8px #ccc;/* for mozila*/
-webkit-box-shadow: 0px 0px 8px #ccc;
    /* For IE upto 5.5 not for 9*/
filter: progid:DXImageTransform.Microsoft.Shadow(color='#cccccc', Direction=45, Strength=3)
progid:DXImageTransform.Microsoft.Shadow(color='#cccccc', Direction=135, Strength=3)
progid:DXImageTransform.Microsoft.Shadow(color='#cccccc', Direction=225, Strength=3)
progid:DXImageTransform.Microsoft.Shadow(color='#cccccc', Direction=315, Strength=3);
}

Answer №3

As mentioned on css3please, this code snippet is recommended: 

.box_shadow {
  -webkit-box-shadow: 0px 0px 4px 0px #ffffff; /* Saf3-4, iOS 4.0.2 - 4.2, Android 2.3+ */
  box-shadow: 0px 0px 4px 0px #ffffff; /* Opera 10.5, IE9, FF4+, Chrome 6+, iOS 5 */
}
