Pointy Slider – A slideshow with sliding-in panels

Today’s resource is a simple, responsive slider, with a sharp design and an interesting motion effect: with each new slide item, a sliding-in block of content covers the old one, and unveils a new image.

Creating the structure slideshow

The HTML structure is composed by two main elements: a ul.cd-slider for the slides, and a ol.cd-slider-navigation for the slider navigation; both are wrapped inside adiv.cd-slider-wrapper.

Note that the ol.cd-slider-navigation element is not directly inserted in the HTML but created using jQuery.

Adding style

On small devices (viewport width smaller than 900px), the slider structure is pretty straightforward: the .cd-slider element has a relative position while its children<li> have an absolute position, with a top and left of zero.
All the list items are translated to the right, outside the viewport (translateX(100%)); the .is-visible class is added to the visible one to move it back into the viewport (translateX(0)).

On bigger devices, the list items are moved back inside the viewport (translateX(0)), while their two children elements, .cd-half-block.content and .cd-half-block.image, are translated to the right (translateX(200%) and translateX(100%) respectively). This way, both elements are outside the viewport, overlapping.

When the .is-visible class is added to the selected list item, the two .cd-half-blockelements are moved back inside the viewport (translateX(0)).
We used CSS3 Transitions to animate both elements: for the .cd-half-block.contentwe set a transition-duration of 0.6s and a transition-delay of 0s, while for the .cd-half-block.image we set a transition-duration of 0s and a transition-delay of 0.3s.
This way, when the .cd-half-block.content has translated of half the total translation value (100%), the .cd-half-block.image is moved back inside the viewport (translateX(0)) instantaneously (transition-duration: 0s). This creates the unveiling image effect.

Here is a quick animation that explains the logic behind the blocks animation (.gif created using After Effects):

One thing to note: we set the .cd-half-block.image transition-delay to be equal to half the .cd-half-block.content transition-duration. This is because we used ease-in-out as timing-function, which assures that after half the transition-duration (in our case .3s), the .cd-half-block.content has actually moved of half the total translation value.

Events handling

We used jQuery to create and insert into the DOM the slider navigation.

Besides, we used jQuery to implement a basic slider functionality (touch swipe and slider navigation).
