disable background using css when popup appear

htmlcss

提问by Milton

I am using the below css code to block the entire page when the popup appeared. But it's working(The visible page only covered not all). I have a problem, if my page having a scroll bar means the remaining bottom of the page not covered by the blocker.

当弹出窗口出现时,我使用下面的 css 代码来阻止整个页面。但它正在工作(可见页面仅涵盖并非全部)。我有一个问题,如果我的页面有滚动条意味着页面的剩余底部未被拦截器覆盖。

.parentDisable
        {
            z-index: 99999;
            width: 100%;
            height: 100%;
            display: none;
            position: absolute;
            top: 0%;
            left: 0%;
            background-color: #000;
            color: #aaa;
            opacity: 0.8;
            filter: alpha(opacity=100);
        }
        #popup
        {
            width: 300;
            height: 300;
            position: relative;
            color: #000;
            top: 25%;
        }
