20 Small, Yet Viable Solutions Based on Flexbox

• 6 minutes READ

Flexbox layout is perhaps one of the most long-awaited features in CSS. It is the “talk of the town.” It is suitable for tablet and mobile applications and small-scale layouts, however, its enormous potential allows it to deal with all sorts of projects, including large-scale ones.

Its primary task is to efficiently use all the available space by manipulating aspects of container items, such as width, height and order. It shrinks or expands its child items to prevent overflow and keep the structure clean and tidy. It is also direction-agnostic so that it feels comfortable on touch screen devices that as a rule, constantly change orientation.

The only thing that clouds its glory is browser incompatibility. Of course, the majority of the latest versions support it, even Blackberry browser 10+ and IE 10 nicely respond to the technology. However, it is not enough and to enjoy the whole benefits, you should mix and match old and new syntax as well as prepare a fallback.

We have gathered 20 viable solutions that are created with Flexbox. Some are frameworks, while others are just tiny code snippets. You can use them at your discretion.
