html – 使用CSS更改背景的亮度

我想改变DIV背景的亮度,而不影响div中的其他内容.

当我在div上应用悬停亮度过滤器时,其中的其他元素也会受到影响.我不想要的.

我的另一个解决方案就是用照片编辑的替换div的背景.但是要求存储量增加一倍,我不喜欢.

有没有办法改变背景图像的亮度？

<div id="replace">
    <div id="transparent">
        <span id="text">Random unaffected text</span>
    </div>
</div>

    <div id="brightnessfilter">
    <div id="transparent">
        <span id="text">Random AFFECTED text (it glows)</span>
    </div>
</div>

#replace {
width:700px;
height:465px;
BACkground-image:url('http://i42.Tinypic.com/351dff5.jpg');
}

#brightnessfilter {
    width:700px;
    height:465px;
    BACkground-image:url('http://i42.Tinypic.com/351dff5.jpg');
}

#brightnessfilter:hover {
     -webkit-filter: brightness(1.3);
-moz-filter: brightness(1.3);
-o-filter:  brightness(1.3);
-ms-filter:  brightness(1.3);
}

#transparent {
    position:relative;
    top:400px;
    width:700px;
    height:65px;
    BACkground-color:rgba(0,.5);
    border-radius:8px;
}

#text {
    color:white;
    font-weight:bold;
    position:relative;
    top:9px;
    left:9px;
    font-size:16px;
}

#replace:hover {
    BACkground-image:url('http://i40.Tinypic.com/2cft7dl.jpg');
}

上面是我用两次尝试创造所需效果的小提琴的链接.但两者都有使用它的缺点.

提前致谢！
