Ensure that the height of the absolute div remains at 100% regardless of the visibility of the

HTML

<div class="overlay" style="display:none;"></div>

CSS:

.overlay{
    position:absolute;
    width:100%;
    height:100%;
    background-color:#000000;
    filter:alpha(opacity=60);
    opacity:0.6;
    -moz-opacity:0.6;
    z-index:100;
    top:0px;
}

JS:

$(".overlay").toggle();

Effect:

A layer has been added above the entire website, preventing user interaction.

Problem:

When a scrollbar appears due to excess content, the overlay does not automatically adjust its height as shown in the image.

How can I ensure the absolute div expands accordingly?

Answer №1

.................................

Hello, let's avoid using the width or height properties and instead opt for the position: fixed attribute.

Here is an example:

.modalPage{
    position:fixed;
    background-color:#000000;
    filter:alpha(opacity=60);
    opacity:0.6;
    -moz-opacity:0.6;
    z-index:100;
    top: 0;
    left:0;
    right:0;
    bottom:0;
}

Answer №2

.overlay{
    position:fixed;
    width:100%;
    height:100%;
    background-color:#000000;
    filter:alpha(opacity=60);
    opacity:0.6;
    -moz-opacity:0.6;
    z-index:100;
    top: 0;
    left:0;
}
