How to make in CSS an overlay over an image?


I am trying to achieve something like this:

this effect

When I hover over an image, I would like to put on that image this dark color with some text and the icon.

I am stuck here. I found some tutorials but they didn't work out for this case. Also, another issue -- every image has a different height. The width is always the same.

How can this effect be achieved?


Solution

  • You can achieve this with this simple CSS/HTML:

    .image-container {
        position: relative;
        width: 200px;
        height: 300px;
    }
    .image-container .after {
        position: absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
        display: none;
        color: #FFF;
    }
    .image-container:hover .after {
        display: block;
        background: rgba(0, 0, 0, .6);
    }
    

    HTML

    <div class="image-container">
        <img src="http://lorempixel.com/300/200" />
        <div class="after">This is some content</div>
    </div>

    UPD: Here is one nice final demo with some extra stylings.

    .image-container {
        position: relative;
        display: inline-block;
    }
    .image-container img {display: block;}
    .image-container .after {
        position: absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
        display: none;
        color: #FFF;
    }
    .image-container:hover .after {
        display: block;
        background: rgba(0, 0, 0, .6);
    }
    .image-container .after .content {
        position: absolute;
        bottom: 0;
        font-family: Arial;
        text-align: center;
        width: 100%;
        box-sizing: border-box;
        padding: 5px;
    }
    .image-container .after .zoom {
        color: #DDD;
        font-size: 48px;
        position: absolute;
        top: 50%;
        left: 50%;
        margin: -30px 0 0 -19px;
        height: 50px;
        width: 45px;
        cursor: pointer;
    }
    .image-container .after .zoom:hover {
        color: #FFF;
    }
    <link href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.min.css" rel="stylesheet"/>
    
    <div class="image-container">
        <img src="http://lorempixel.com/300/180" />
        <div class="after">
            <span class="content">This is some content. It can be long and span several lines.</span>
            <span class="zoom">
                <i class="fa fa-search"></i>
            </span>
        </div>
    </div>
