Flexbox is the Future

Have you ever spent hours agonizing over a CSS layout that just wouldn't work? Have you struggled with columns, vertical centering, floats or inline displays? Have you even, gasp, given up and used tables for your layouts?

It’s time to say goodbye to all that pain. Flexbox is a new CSS standard that lets you create fluid application layouts with very little effort. It works in all modern browsers, and you don’t need any special tools or languages to use it.

Browser support for flexbox has come a long way in the last few years. 95% of people are running a browser that supports flexbox, and that number is growing every day. There’s no reason to wait to use flexbox!

Frequently Asked Questions

Can I really use flexbox today? Is it supported on IE?

Flexbox is now supported by 95% of all internet traffic! The best kept secret of flexbox is that you can use it today and it will work almost everywhere!

Flexbox works great in all modern browsers, including Internet Explorer 10+, Firefox, Chrome, Safari, Opera, iOS Safari, Opera Mini, Android 4.1+ and Chrome for Android.

What about older browsers? I need to support IE9. How does my site display on browsers that don’t support flexbox?

In this book, you’ll learn how to leverage progressive enhancement to display a simpler layout on older browsers.

Ugh, I hate all those vendor prefixes. Is there a way I can write flexbox without them?

Yes! In the book, I’ll show you how to set up your environment so you can ignore all vendor prefixes. You’ll write your code once, and it will work everywhere!

Why don’t I just use a CSS framework like Bootstrap or Foundation? Don’t those already have a grid system?

Bootstrap and Foundation include basic 12-column grid systems. For more complex layouts they fall short. Those frameworks are also bloated monsters, adding a lot of weight and complexity to your site. If all you’re looking for is a grid, flexbox is lightweight, portable and powerful.

Is flexbox even standardized yet?

Flexbox has stabilized and is implemented in all major browsers. At this point, the specification is extremely unlikely to change.
