The responsive CSS animation framework

For creating sliders, presentations, banners, and other step-based applications

.seq-in .content { transform: translateY(0); transition: .2s; }

Step 1

Easily add CSS transitions to step-based applications using "in" and "out" CSS classes

Step 1 is currently in its in¹ position. Watch what happens when you go to the next step →
.seq-out .content { transform: translateY(-100%); transition: .2s; }

.content { transform: translateY(100%); }

.seq-in .content { transform: translateY(0); transition: .25s; }

Step 2

Sequence.js takes care of the functionality so you can concentrate on presenting your content in style

By going to the next step, you caused step 1 to transition from in¹ to out² and step 2 to transition from start³ to in⁴. All with just several of lines of CSS.

When navigating backwards Sequence.js can automatically reverse these transitions.
.seq-in .rotate { animation-name: rotate; animation-duration: 1s; }

.seq-in .fade { animation-name: fade; animation-duration: 1s; }

.seq-in .threed { animation-name: threed; animation-duration: 1s; }
Step 3

Create unique animated applications using any CSS properties you wish

Sequence.js doesn't limit you to specific HTML/CSS. Use the properties, attributes, workflow, conventions, and libraries you're familiar with.

.seq-in .touch { animation-name: rotate; animation: .35s 1.8s; }

.seq-in .touch-title-1 { animation-name: fade-out; animation: .3s 1.5s; }

.seq-in .touch-title-2 p { animation-name: slide-in; animation: .3s 2.35s; }
