Transition. The transition property is a shorthand property used to represent up to four transition-related longhand properties: That div will take half a second when the mouse is over it to turn from red to green.
Here is a live demonstration of such a transition: Check out this Pen! You can specify a particular property as we have above, or use a value of "all" to refer to transition properties. In this above example, both background and padding will transition, due to the value “all” specified for the transition-property portion of the shorthand. You may comma separate value sets to do different transitions on different properties: For the most part, the order of the values does not matter -- unless a delay is specified. Some properties cannot be transitioned because they are not animatable properties.
By specifying the transition on the element itself, you define the transition to occur in both directions. Check out this Pen! Related Properties Other Resources Browser Support. 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.).

We got 99 viewports, but the iPhone's just one. —Josh Brewer, March 10, 2010 A major component of responsive design is creating the right experience for the right device. With a gazillion different devices on the market, this can be a tall task. We've rounded up media queries that can be used to target designs for many standard and popular devices that is certainly worth a read. If you're looking for a comprehensive list of media queries, this repository is a good resource. If you're reaction to this is: you should never base your breakpoints on devices!!

Just in case you have brain farts about this constantly like I do.
If That's what media queries are: logical if statements. "If" these things are true about the browser, use the CSS inside. And The keyword and. Or Comma separate. Technically these are treated like two separate media queries, but that is effectively or. Not Reverse the logic with the keyword not. Just doing not (max-width: 600px) doesn't seem to work for me, hence the slightly funky syntax above. Exclusive To ensure that only one media query is in effect at time, make the numbers (or whatever) such that that is possible.
Logically this is a bit like a switch statement, only without a simple way to do "if none of these match do this" like default. Overriding There is nothing preventing more than one media query from being true at the same time. Media queries add no specificity to the selectors they contain, but source order still matters.
