Aligned row of native Social Sharing buttons with counts (and robust Accessibility)

Demo here.

Shows a row of native social sharing buttons with counts, for Twitter, Facebook, Google+ and LinkedIn. Sharing is still possible without JavaScript and also in text-only modes, via url APIs. Uses Bootstrap for column placement.

On mobile phone screens (xs), the row becomes two rows with one button on each.

On UNIX, see the text-only experience with terminal command lynx http://eusebius.tech/#social-share-buttons

Replace EusebiusTech in Twitter with your own hashtags. %23 is the url encoding of #. See docs for more info.
