This tip only applies if you have Adobe Illustrator CC (Creative Cloud). I confirmed it works in that, or the even newer CC 2014.
It’s as simple as can be: copy from Illustrator, paste into HTML.
What is on your clipboard when you copy in Illustrator is apparently SVG syntax. Pretty dang useful sometimes. Just remember to clean house as needed as often what you get out of Illustrator isn’t perfectly ideal for the web.
