Cards play a large part in Material Design. If you are interested in implementing that type of design, enjoy the convinces of a CSS framework (Icons, responsive grid, etc), and aren't married to Bootstrap I'd suggest taking a look at http://materializecss.com
Very cool framework. I tend to avoid using this sort of framework for my applications because I'll usually end up having to hack around their components and styles, or because I only need 1 or 2 components and I don't wanna pull in everything. However, I'm definitely gonna be referencing some of their stuff for my own implementations.
Visually, a card often has a header and/or footer and is generally embeddable into a standard article body (e.g. Twitter's embeddable tweet cards). Content-wise, a card serves a very specific semantic purpose: presenting a self-contained block of data to a user in a standalone way. The metaphor employed here is something like a trading card or baseball card, such that a block of data or metadata about a particular subject is called out in a self-contained way that is easily understandable and digestable.
I just saw this the other day while researching card ui concepts for an idea I was formulating. On the one hand, I'm very excited about how easy it will be to make a card ui with this. On the other hand, I was kind of sad that I'm coming into card ui so late that it's about to be the next big overused thing.
There are actually two products: XControls.org, which augments IBM Domino XPages and also XComponents.org for an Angular.js environment.
This is one of those open source tools that I'd love to see mature into a commercial offering: emailing request tickets, getting bugs fixed, having access to frequent release candidates, etc. I emailed them awhile back asking for commercial license and inquiring about any support they could offer. They're open to the idea, but seem very new to the game.
We've really taken to the "card" design here, too. We've mixed it with Packery (our angular-packery for an Angular wrapper) using the card headers as drag targets, which works really well. I haven't seen this library before but as we need to get serious about organizing our implementation, this may come in handy.
Was hoping this would be a device with a bootloader capable of reading QR codes printed on cards, or maybe a historical perspective about the boot process of a punched card computer.
I like it but it has a bit of a dated look to it. I think to really take off, this project's UI should improve on Bootstrap itself, perhaps taking cues from Material and iOS. Also, the icons are overused.
I get that this is just starting and it is emphasizing structural elements of the UI, but it would be great to evolve the Bootstrap look which has some residual heaviness to it IMHO.
