Fanning Cards with CSS

I was thinking of fanning out some cards to demonstrate options for one of our sites, and I wanted to do it in CSS, so I came up with this (Plan for fall-back in non-supporting browsers is just a button that shows the options). The plan is to show all options in full when the stack is clicked on, but right now it just fans out on hover.

This isn't anything terribly ground-breaking or difficult, but it is a nice, fun effect so I thought I'd share.

Edit:

I updated the link and code here to point to an updated version of the code that uses the css3 :target selector to spread out the cards when a link is clicked, and collapse them when it's closed.

(See the full page example for better effect)

See the Pen Fanning Cards by Thomas Pietrosanti (@Rykus0) on CodePen.

I used SASS to do handle some of the incremental and procedural parts, but did not leverage Compass, since I am not using it.

Really, all I'm doing is absolutely positioning divs on top of each other, making the transition origin to the bottom center, and rotating around the Z axis between -45° and 45° in regular intervals (determined by the number of cards).

I also added a drop-shadow for kicks that gets bigger as the cards go up - though this makes it look more like stairs, it does add a little depth.

Note that there was no javascript used in this example!

For an example of this in the wild, see the AWV Architectural Finishes page

Element.focus() in IE9 running Jasmine tests with Karma

I recently udpated our Jasmine unit tests to run in Karma ; expanding our browser coverage, adding code coverage reports , and using fixtures for testing DOM manipulation . One of my tests kept failing in IE9, but only when I ran from the console. If I attempted to debug in the browser, everything passed. It turns out that IE9 (at least) needed a few ms to catch it's breath before correctly focusing on the starting element. To do this, I just added a 100ms delay before each test ran (Using Jasmine 2.3). beforeEach(function(done){ loadFixtures('myfixture.html'); // Setting focus in IE requires a delay to work correctly! setTimeout(function(){ done(); }, 100); });

CSS line-height Units Explained

In Chris Coyier's recent article, " Fun with line-height! ", he mentions that we often use unitless values for line-height so that it's proportional to the font size. This is only part of the story, and I was reminded of a Stack Overflow question that got me investigating more about how line-height worked with regards to the various CSS units. If you're declaring the line-height on each element, you won't notice any difference. But if you're not crazy and using the first C of CSS (that's 'Cascading', by the way), then the inherited line-height might not work the way you expect. Disclaimer: This is my understanding after doing some research and testing. I may not be completely correct. TL;DR When using a relative unit (em, %), the line-height is calculated based on the font size of the element where the line-height is defined. This line-height is then inherited, unchanged, by each of its descendants. So we end up with a line...

Flags vs Vendor Prefixes for Experimental CSS

Google recently announced that it will be switching Chrome's rendering engine to a fork of Webkit, called “Blink”. If you're interested, you can read their blog post about Blink . One of the changes we will be seeing in Blink, is the use of browser flags in place of vendor prefixes . What this means, is that rather than prefixing experimental CSS with -webkit-, -moz-, -ms-, -o-, -khtml-, etc.; We will be required to enable these attributes using a flag in the browser (like the ones currently at chrome://flags). If you ask me, both ways have their advantages and disadvantages. Though, in the end, I lean towards the flags over the vendor prefixes, and here's why: #1 Code Bloat On average, using CSS with vendor prefixes requires writing it 5 times . Every time you use it . #2 Future Friendly Eventually, prefixed code will be replaced by the unprefixed code. #3 Browser Dev Friendly Browsers tend to continue to support the prefixed code, even if it doesn...
