html - css 中的百分比宽度不起作用

Question

我使用一种方法通过视口(viewport)测量在 css 中定义我的宽度属性，css 代码:

#content {
    position: absolute;
    background-color: white;
    width: 100vw;
    top: 115px;
    bottom: 30px;
    display: table;
    z-index: 0;
}

当我改变宽度时 width: 100vw;宽度:100%；我的代码不再工作了。我想更改为百分比测量，因为我发现视口(viewport)在 Android < 4.4

上不起作用

}

使位置 relative 而不是 absolute ，然后 width:100% 应该可以工作

#mainslide {
    position: relative;
    left:100%
    z-index: 1;
}
#aanbod {
    position: relative;
    left: 0px;
}
.tablestyleorchideeaanbod {
    width: 100%;
    padding: 12px;
    padding-left: 8%;
    padding-right: 8%;
    border-bottom-width: 1px;
    border-top-width: 0px;
    border-left-width: 0px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #8cca49;
}
#content {
    position: absolute;
    background-color: white;
    width: 100%;
    top: 115px;
    bottom: 30px;
    display: table;
    z-index: 0;
}
