Fixes #33

[jpoles1]

In my first commit, I add node-sass as a dev dependency, and while not technically necessary, use it to build the project js and css files.

In the second commit I have made the modifications to fix the possibly non-unicode "x" character for closing the box. This was displaying incorrectly as shown in issue #33 . I had to edit the css in order to make the "x" render in the right place on desktop. I have not been able to check that this works on mobile as of yet.

May make a demo page for this repo for testing purposes which can help the user (and editor) see what it looks like. I guess this would be a page with settings to consider all browsers "out of date".

Very simple demo page can be seen here. Seems that this fix works on my mobile device.

• I love the demo page idea by setting everything to false
• Ah I understand, the 'multiply x' vs the 'letter x'. I do think the old multiply one looks better but the point is this should work everywhere so you're right let's change the character.
• I'll merge all of these - they're cool - but really they should be separate PRs - 'Use better x character' 'Support npm build' 'Add a demo page' etc. Just makes history easier to read!

Got it, will work to separate out my PRs in the future. Recommend enabling ghpages for this repo, and adding a link to the README if you weren't already going to.

Done!
