Drag and Drop and HTML5. As you know (I hope), all modern browsers (it should be FF, Safari, Chrome, possible Opera) have native support of this useful feature (as drag and drop). It means that we can use it in our projects, the code won’t be very difficult. And, as the example of practical implementation, let assume that we have to sort some media (images) between some albums.

Step 1. HTML

index.html

<div class="albums">
    <div class="album" id="drop_1" droppable="true"><h2>Album 1</h2></div>
    <div class="album" id="drop_2" droppable="true"><h2>Album 1</h2></div>
    <div class="album" id="drop_3" droppable="true"><h2>Album 3</h2></div>
</div>
<div style="clear:both"></div>
<div class="gallery">
    <a id="1" draggable="true"><img src="images/1.jpg"></a>
    <a id="2" draggable="true"><img src="images/2.jpg"></a>
    <a id="3" draggable="true"><img src="images/3.jpg"></a>
    <a id="4" draggable="true"><img src="images/4.jpg"></a>
    <a id="5" draggable="true"><img src="images/5.jpg"></a>
    <a id="6" draggable="true"><img src="images/6.jpg"></a>
    <a id="7" draggable="true"><img src="images/7.jpg"></a>
    <a id="8" draggable="true"><img src="images/8.jpg"></a>
    <a id="9" draggable="true"><img src="images/9.jpg"></a>
    <a id="10" draggable="true"><img src="images/10.jpg"></a>
    <a id="11" draggable="true"><img src="images/11.jpg"></a>
    <a id="12" draggable="true"><img src="images/12.jpg"></a>
</div>
<script src="js/main.js"></script>

You can see here three droppable objects (our virtual albums) and twelve images. I have marked droppable albums with attribute ‘droppable’, and draggable objects with attribute ‘draggable’.

Step 2. CSS

Now, its time to style our example. It possible that you have noticed that styles of our today’s lesson looks like the styles of our previous demonstration (where I described how to create pure css3 gallery). I updated those styles for today’s lesson.

css/main.css

/* Photo Gallery styles */
.gallery {
    margin: 50px auto 0;
    width: 840px;
}
.gallery a {
    display: inline-block;
    height: 135px;
    margin: 10px;
    opacity: 1;
    position: relative;
    width: 180px;

    -khtml-user-drag: element;

    /* CSS3 Prevent selections */
    -moz-user-select: none;
    -webkit-user-select: none;

    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;

    transition: all 0.5s ease;
}
.gallery a img {
