It creates intelligent boxes that are stretchable, squeezable and capable of changing visual order. It provides simple solutions to layout paradigms that CSS has always struggled with: vertical centering and equal heights. Flex items are truly accommodating and a pleasure to work with. Chris Coyier sums up flexbox2 nicely: 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).

Flexbox truly shines with HTML5 web applications. Browser Support Desktop: Touch: Touch: Opera Mini. A Designer’s Guide To Flexbox. This article is also available in Czech. Flexbox is a new and very powerful CSS layout module, one completely divorced from web practices of the past.

At the basic level, flexbox has three features that are fundamental to design, but which have long been difficult or impossible to achieve in CSS: alignment, distribution, and ordering.

In this article we are going to take a look into the unique challenges of drawing images in the canvas in the context of HiDPI screens. The devicePixelRatio property Let's start at the beginning. That's interesting, but what does that mean for us developers? The de facto solution to this has been to create images scaled up by the devicePixelRatio and then use CSS to scale it down by the same amount. Introducing the backing store What about the canvas?
