html - 阻止文本随背景颜色一起褪色

Question

我正在创建 2 个框，悬停时它们会淡化为红色，但我希望文本保持完全白色并且不随背景/图像一起淡化。我在编码方面不是很先进，但如果可能的话，如果有任何帮助和现场演示，我们将不胜感激？

CSS

.image {
    position:relative;
    width:400px;
    height:200px;
    background-color:#555555;
    color: #ffffff;
}
.image img {
    width:50%;
    vertical-align:top;
    color: #ffffff;
}
.image:after, .image:before {
    position:absolute;
    background-color:rgba (255,0,0,1);
    opacity:0;
    transition: 0.5s ease;
    -webkit-transition: 0.5s ease;
    color: #ffffff;
}
.image:after {
    content:'\A';
    width:100%; height:100%;
    top:0; left:0;
    background-color:rgba(255,0,0,0.75);
    color:#ffffff;
}
.image:before {
    width:50%;
    color:#fff;
    z-index:1;
    bottom:0;
    padding:4px 10px;
    text-align:center;
    background-color:red;
    box-sizing:border-box;
    -moz-box-sizing:border-box;
    color: rgba(255,255,255,0);
}
.image:hover:after, .image:hover:before {
    opacity:1;
}
.text {
    padding-left:210px;
    padding-right:10px;
    margin-top:-190px;
    color:rgba(255,255,255,10);
    font-family:Arial;
    font-size:15px;
    opacity: 1;
}

HTML

<div class="image">
    <img src="http://www.newyorker.com/online/blogs/photobooth/NASAEarth-01.jpg" alt="" />
    <div class="text">
        <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor     incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud.</p>
    </div>
</div>

Answer 1

因为你想让文本保持在前面，只需使用 z-index 将它添加到你的 CSS 中:

.text {
    position:relative;
    z-index:1;
}

如果您也想要前面的图像，请使用相同的属性 http://jsfiddle.net/2qekazm4/2/
