Flexbox, align-items correct syntax and usage - flexbox

I have made several attempts to use the align-items command in my CSS code. I am able to complete all Flexbox "positions" across the Main Axis. However, when manipulating <div>s and such along the Cross Axis(vertically) I have no success.

You can play with that: http://the-echoplex.net/flexyboxes/
It should get you up and running.

WebVR show html content

I'd like to create a virtual space where I want to mix 3D elements and html content. I have seem some demos with WebVR but didn't work for me. WebAR is also an interesting option.
Thanks
Unfortunately, this isn't possible at the moment, because
there is no proper way to get your hands on the rastered output of the HTML in order to use it as a texture in WebGL and
there is no way to get any html-element shown in a WebVR-context
There is certainly work being done in both directions, but your best bets would probably be a-frame (https://aframe.io/) or reactVR (https://developer.oculus.com/blog/introducing-the-react-vr-pre-release/) which both at least have a bit of that html-feeling to it and can handle text pretty well (nothing compared to the power of html+css, but they will get there at some point).
Another option is to use a library like html2canvas (https://html2canvas.hertzen.com/) to get some rendered output from a piece of html which you can then use as a texture. Also has it's limits but might be worth a try...
Have fun!

Displaying binomials and matrices using asciimath with mathjax

I'm trying to display different math problems using asciimath and mathjax. However some things does not seem to be supported in asciimath. For instance I'm trying to display a binomial/matrix and I can't really figure out how to do it. Would I have to use latex or mathml to do this, or is there a way to use asciimath for this?
update: I found a kinda cheeky way to show binomials in asciimath: (""_1^2) This works, but it is kinda hacky.
You can use
([1],[3])
to get a matrix with two rows of one element each surrounded by parentheses. That may be what you want, though it may be too tall for use with in-line expressions.

Advanced CSS Circles

I'm trying to make 3 different circles to my website. I don't want to insert it as a graphic/image file. So I've been trying to achieve it using CSS3, but I can't really work my fingers around it.
What will it look like?
I have uploaded a picture of what I'm trying to achieve at: www.sp34k.com/etc/circles.jpg
I can't really show the code I've been trying to use to achieve this, as it all looks totally weird and nothing floats currectly.
What I've tried
What I've tried is to make 3 circles with position absolute and then use % (percentage) to determine the width of the colored parts, but I can't twist my mind around how it should be set up.
Any suggestions is appreciated,
Mike
Here is a simple try of me to achieve the effect you want:
DEMO
edit: css-only solution
It can be easily animated with javascript or keyframes. Arbitrary content would go into the inner div. To change the percentage, simply adjust the angle of the pseudo-elements.
With a little more effort this could be easily refined I guess;)
Note: the transform has the webkit-prefix, so it works only in chrome/safari - to see it in firefox or other browsers, you need to change the prefix.
P.S. I will animate it when I'm home from work.
Good one by Christoph but he is using SASS/SCSS which are comparatively slow then normal CSS because they have to be converted to CSS before browser render it so I have have a different Solution for you

Map: mix regions and markers

I need to display both color coded states and cities on a US map.
Is this possible with Google geocharts?
http://developers.google.com/chart/interactive/docs/gallery/geochart#Configuration_Options
Basically what I'm looking for is a way to mix the regions and markers display modes.
If not, any alternate options to achieve this?
I also answered a similar question here, but here it goes again:
Regions and Markers wont work at the same time. So if you want to color the background of the states, using markers mode, you can do it with CSS.
I'm documenting some examples for a Wordpress plugin i developed here: http://cmoreira.net/interactive-world-maps-demo/advanced-customization/
Check the last example. It's not easy, since you have to find which child path number you want to color, and then you can do it. Example:
#visualization path:nth-child(5) {
fill:#cccccc;
}
Here's an example, forkerd from another user, with the CSS above: http://jsfiddle.net/cmoreira/Jqkjg/
Hope it helps!
No, this is impossible with GeoCharts. I would recommend you to try jVectorMap library for that.

javascript raphael - how to stroke individual paths?

I am trying to make a tool for my website which traces over Japanese characters, showing the stroke order etc.. something like this: http://www.chinesehideout.com/tools/strokeorder.php?c=5pel
I have made a bunch of SVG files in inkscape, which are made up of just curves, one for each stroke of the character. I have then imported these into Raphael using the raphael-svg-import: https://github.com/wout/raphael-svg-import
The SVGs are displaying perfectly, however I want to animate them.
My question is: Is there a way to take each path from the SVG in turn in Raphael, and then animate/stroke them? If so..how??
If you need any more info please say!
Thanks
EDIT: Perhaps I should clarify, when I say stroke I mean progressively draw the line, starting from the first point and ending at the last. At the moment it draws all paths simultaneously and draws the whole of each path at once.
The technique people use in svg for doing this is outlined in this answer. It's probably possible to adapt that to Raphaël, though the Raphaël documentation doesn't list stroke-dashoffset.
Raphaël has a method Element.getSubpath(from, to) that can be used to get only part of a path, that should probably also be an option.
