Some tweaks to the HTML.

Daniel Arthur Gallagher · Daniel Arthur Gallagher · commit 15c550250cc6 · 2017-06-26T14:27:22.000+01:00
I've removed the "type" attributes from the script and style attributes, since in HTML5 these are not needed.
I made the tracking script specifically use HTTPS rather than be protocol-relative.
I added "noopener" to the anchors to other domain.
