CSS Flexbox. Value of the display property is currently: -moz-box Item 1 Item 2 Item 3 The interesting thing about this technique is that no floats whatsoever are being used.
The default value for the flex-direction property is row. Start End Justify Center Being able to center items inside a flexbox is a very powerful thing; in the future this may save developers the hassle of having to resort to hacks to achieve centering of an item within a container. Baseline Stretch Note: All items within example 4 do not have their heights explicitly set. Note: The style flex: 1; has been applied on each of the three items. Here's an example of using flex: 2; on the 2nd item only (div:nth-child(2)) , and keeping flex: 1; on the remaining items.
Mastering CSS Layout with Flexbox. UPDATE: This page is still good, but I recommend this course on flexbox I've put together.
It includes an updated version of this page plus more videos and a cheat sheet. Laying out a design with CSS is fraught with peril of cross-browser bugs and mysteriously collapsing margins. But new tools like flexbox have transformed this once odious task into something you shouldn't dread. By the end of this chapter you'll be coding up new layouts for your design faster than you can think of them. Remember those old cartoons with the road runner and the coyote? Using CSS to layout your design is like trying to catch the road runner with a jet-powered pogo stick. Nothing is more frustrating than writing a pile of code, refreshing your browser and seeing a jumbled mess of overlapping text and images. But you know what? Flexbox Once you spend some time with flexbox you'll feel like an unstoppable super hero of CSS. "Wait, let's not get carried away" you say, "Flexbox is too new.
It doesn't matter. A Complete Guide to Flexbox. Background The Flexbox Layout (Flexible Box) module (currently a W3C Last Call Working Draft) aims at providing a more efficient way to lay out, align and distribute space among items in a container, even when their size is unknown and/or dynamic (thus the word "flex").
The main idea behind the flex layout is to give the container the ability to alter its items' width/height (and order) to best fill the available space (mostly to accommodate to all kind of display devices and screen sizes). A flex container expands items to fill available free space, or shrinks them to prevent overflow. Most importantly, the flexbox layout is direction-agnostic as opposed to the regular layouts (block which is vertically-based and inline which is horizontally-based). While those work well for pages, they lack flexibility (no pun intended) to support large or complex applications (especially when it comes to orientation changing, resizing, stretching, shrinking, etc.).
Basics & Terminology display. Solved By Flexbox — Cleaner, hack-free CSS. All of the code samples on this site show how to solve a particular design problem with Flexbox.
They show just the code that's needed to make the demos work in a spec-compliant browser. Some browsers do not fully comply with the latest version of the spec, so sadly, a few workarounds were necessary. Workarounds for non-compliant browsers are not shown in the code samples, but if you're curious about those implementation details, you can check out the source files.
Each demo links to its source, and all browser-specific workarounds are well-documented, so don't be afraid to take a look. The vendor prefixing and translating of current flex properties to their legacy equivalents is all handled by autoprefixer. The class naming convention used in the code samples and source files is taken from SUIT CSS, which is based on BEM methodologies.

In the flex layout model, the children of a flex container can be laid out in any direction, and can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children can be easily manipulated. Nesting of these boxes (horizontal inside vertical, or vertical inside horizontal) can be used to build layouts in two dimensions. CSS is a language for describing the rendering of structured documents (such as HTML and XML) on screen, on paper, in speech, etc. Status of this document This is a public copy of the editors’ draft.
