Awesome CSS3 Photo Gallery

· Web Dev Zone

Learn why developers are gravitating towards Node and its ability to retain and leverage the skills of JavaScript developers and the ability to deliver projects faster than other languages can.  Brought to you in partnership with IBM.

In our new tutorial I am going to develop an awesome image lightbox-like gallery with using CSS3 (and without any javascript!). And yes, you heard right. Today, we won’t use scripts at all. I am going to use these CSS3 properties: user-select, box-sizing, transition, box-shadow and transform.

First, I suggest you download the source files and keep the demo opened in a tab for better understanding.

So, lets start.


Step 1. HTML

Everything is very easy, isn’t it? You can just focus your attention only on the ‘tabindex’ attribute. This property sets the tab order for elements.

index.html

<div class="gallery">
    <a tabindex="1"><img src="images/1.jpg"></a>
    <a tabindex="2"><img src="images/2.jpg"></a>
    <a tabindex="3"><img src="images/3.jpg"></a>
    <a tabindex="4"><img src="images/4.jpg"></a>
    <a tabindex="5"><img src="images/5.jpg"></a>
    <a tabindex="6"><img src="images/6.jpg"></a>
    <a tabindex="7"><img src="images/7.jpg"></a>
    <a tabindex="8"><img src="images/8.jpg"></a>
    <a tabindex="9"><img src="images/9.jpg"></a>
    <a tabindex="10"><img src="images/10.jpg"></a>
    <a tabindex="11"><img src="images/11.jpg"></a>
    <a tabindex="12"><img src="images/12.jpg"></a>
</div>

Step 2. CSS

Now, it's time to style our gallery. Don’t forget to include our CSS file in the head section of the result page.

css/main.css

/* Photo Gallery styles */
.gallery {
    margin: 100px auto 0;
    width: 800px;
}
.gallery a {
    display: inline-block;
    height: 135px;
    position: relative;
    width: 180px;

    /* CSS3 Prevent selections */
    -moz-user-select: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    user-select: none;
}
.gallery a img {
    border: 8px solid #fff;
    border-bottom: 20px solid #fff;
    cursor: pointer;
    display: block;
    height: 100%;
    left: 0px;
    position: absolute;
    top: 0px;
    width: 100%;
    z-index: 1;

    /* CSS3 Box sizing property */
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
    -o-box-sizing: border-box;
    box-sizing: border-box;

    /* CSS3 transition rules */
    -webkit-transition: all 1.0s ease;
    -moz-transition: all 1.0s ease;
    -o-transition: all 1.0s ease;
    transition: all 1.0s ease;

    /* CSS3 Box Shadow */
    -moz-box-shadow: 2px 2px 4px #444;
    -webkit-box-shadow: 2px 2px 4px #444;
    -o-box-shadow: 2px 2px 4px #444;
    box-shadow: 2px 2px 4px #444;
}

/* Custom CSS3 rotate transformation */
.gallery a:nth-child(1) img {
    -moz-transform: rotate(-25deg);
    -webkit-transform: rotate(-25deg);
    transform: rotate(-25deg);
}
.gallery a:nth-child(2) img {
    -moz-transform: rotate(-20deg);
    -webkit-transform: rotate(-20deg);
    transform: rotate(-20deg);
}
.gallery a:nth-child(3) img {
    -moz-transform: rotate(-15deg);
    -webkit-transform: rotate(-15deg);
    transform: rotate(-15deg);
}
.gallery a:nth-child(4) img {
    -moz-transform: rotate(-10deg);
    -webkit-transform: rotate(-10deg);
    transform: rotate(-10deg);
}
.gallery a:nth-child(5) img {
    -moz-transform: rotate(-5deg);
    -webkit-transform: rotate(-5deg);
    transform: rotate(-5deg);
}
.gallery a:nth-child(6) img {
    -moz-transform: rotate(0deg);
    -webkit-transform: rotate(0deg);
    transform: rotate(0deg);
}
.gallery a:nth-child(7) img {
    -moz-transform: rotate(5deg);
    -webkit-transform: rotate(5deg);
    transform: rotate(5deg);
}
.gallery a:nth-child(8) img {
    -moz-transform: rotate(10deg);
    -webkit-transform: rotate(10deg);
    transform: rotate(10deg);
}
.gallery a:nth-child(9) img {
    -moz-transform: rotate(15deg);
    -webkit-transform: rotate(15deg);
    transform: rotate(15deg);
}
.gallery a:nth-child(10) img {
    -moz-transform: rotate(20deg);
    -webkit-transform: rotate(20deg);
    transform: rotate(20deg);
}
.gallery a:nth-child(11) img {
    -moz-transform: rotate(25deg);
    -webkit-transform: rotate(25deg);
    transform: rotate(25deg);
}
.gallery a:nth-child(12) img {
    -moz-transform: rotate(30deg);
    -webkit-transform: rotate(30deg);
    transform: rotate(30deg);
}

.gallery a:focus img {
    cursor: default;
    height: 250%;
    left: -150px;
    top: -100px;
    position: absolute;
    width: 250%;
    z-index: 25;

    /* CSS3 transition rules */
    -webkit-transition: all 1.0s ease;
    -moz-transition: all 1.0s ease;
    -o-transition: all 1.0s ease;
    transition: all 1.0s ease;

    /* CSS3 transform rules */
    -moz-transform: rotate(0deg);
    -webkit-transform: rotate(0deg);
    -o-transform: rotate(0deg);
    transform: rotate(0deg);
}

As you can see, in order to have our images look like polaroid photos, I use the css3 transformation: rotate. To achieve the popup effect I use special selector ‘:focus’ (this pseudo-class matches any element that has keyboard input focus). Do you remember that we made different ‘tabindex’ attributes? Now, it will allow you to use even ‘tab’ (or ‘shift+tab’) keyboard button to switch between images. Its nice, isn’t it?
