Why is all of this so important? Why is it worth your time to perfect your transitions

and easing combinations? For the same reason that designers spend hours perfecting

their font and color combinations: reﬁned products simply feel superior. They leave

users whispering to themselves, “Wow, this is cool,” right before they turn to a friend

and exclaim, “You gotta see this!”

an introductory HTML and CSS book before reading this one.

JAVASCRIPT VS. CSS ANIMATION

There’s a false belief in the web development community that CSS animation is the only

performant way to animate on the web. This misconception has led many developers to

abandon JavaScript-based animation altogether, forcing them to

Manage the entirety of user interface (UI) interaction within style sheets, which can

quickly become diﬃcult to maintain.

Sacriﬁce real-time animation timing control, which is achievable only within

JavaScript. (Timing control is necessary for designing animation into UIs that

respond to a user’s drag input, like those found in mobile apps.)

Forgo physics-based motion design, which allows elements on a webpage to behave

like objects in the real world.

Lose support for older browser versions, which remain popular throughout

theworld.

JavaScript-based animation is actually often as fast as CSS-based animation. CSS

animation is mistakenly considered to have a signiﬁcant leg up because it’s most often

compared to jQuery’s animation features, which are in fact very slow. However, alterna-

tive JavaScript animation libraries that bypass jQuery entirely deliver fantastic perfor-

mance by streamlining their interaction with a page.

Of course, CSS is perfectly suited for hover state animations (turning a link blue

when the mouse is positioned over it, for example), which are very often the extent to

which basic webpages include animation. CSS transitions ﬁt seamlessly into existing

stylesheets, allowing developers to avoid bloating their pages with unnecessary

JavaScript libraries. What’s more, CSS animation delivers blazing performance out

ofthe box.

But this book will demonstrate why JavaScript is often the superior choice for

animations beyond simple hover state animations.

: One library of note, which we’ll be using throughout this book,

is Velocity.js. It’s lightweight yet incredibly feature rich, and it mirrors

jQuery’s animation syntax to help eliminate the learning curve.
