为什么没有覆盖整个屏幕宽度?
why no whole width of screen is covered?
我使用css和JavaScript来锁屏,但我不知道为什么锁屏和屏幕的宽度不一样,你知道吗?
这是 HTML 源代码,您发现 javascript 代码如下,有人帮助我吗?
JavaScript:
function FreezeScreen(msg) {
scroll(0,0);
var outerPane = document.getElementById('FreezePane');
var innerPane = document.getElementById('InnerFreezePane');
if (outerPane) outerPane.className = 'FreezePaneOn';
if (innerPane) innerPane.innerHTML = msg;
}
HTML:
<body>
<div align="center" id="FreezePane" class="FreezePaneOff">
<div id="InnerFreezePane" class="InnerFreezePane"> </div>
</div>
CSS:
.FreezePaneOff {
visibility: hidden;
display: none;
position: absolute;
top: -100px;
left: -100px;
}
.FreezePaneOn {
position: absolute;
top: 0px;
left: 0px;
visibility: visible;
display: block;
width: 100%;
height: 100%;
background-color: #666;
z-index: 999;
filter:alpha(opacity=85);
-moz-opacity:0.85;
padding-top: 20%;
}
.InnerFreezePane {
text-align: center;
width: 66%;
background-color: #171;
color: White;
font-size: large;
border: dashed 2px #111;
padding: 9px;
}
如果你想让它覆盖屏幕,你可以将 position:absolute
更改为 position:fixed
Position property :
absolute - The element is positioned relative to its first positioned
(not static) ancestor element.
fixed - The element is positioned relative to the browser window.
我用两种方法解决了我的问题,方法2不好,因为固定宽度,但我不确定为什么方法1可以,有人给我解释一下吗?
方法一:
.FreezePaneOn {
...
width: 103%;
height: 100%;
...
}
方法二:
.FreezePaneOn {
...
width: 990px;
height: 100%;
...
}
