How to Create a Slider to Zoom Photos
If you’ve ever used a piece of software, like Picasa or iPhoto before, you’ll be aware of the fact that there is a slider at the bottom, which allows you to specify how large each photo should be. Move the slider up a few ticks, and all the photos will zoom in a bit. Thanks to the HTML5 and the new
range input, we can mimic this effect rather easily. Along the way, we’ll also learn about a variety of awesome new CSS3 features, including transition, nth-child, rotations, scaling, and more.
