Talking about Web Components with Eric Bidelman

In Sep­tem­ber of last year I asked Google’s Eric Bidel­man some ques­tions about web com­po­nents for a fea­ture I was writ­ing. Unfor­tu­nate­ly it turned out there was no room in the arti­cle for Eric’s answers, but I recent­ly stum­bled across them again and decid­ed they are too good to go to waste, so here they are.

Thanks very much to Eric for answer­ing my ques­tions, and apolo­gies if the pas­sage of time has out­dat­ed any answers.

CSS Blending — a Five-minute Introduction

I remem­ber read­ing about muta­tion observers a lit­tle while ago, but didn’t pay them too much atten­tion as they didn’t have broad brows­er sup­port and weren’t imme­di­ate­ly use­ful to me. When I recent­ly saw object observers land in Chrome (36) Beta, I realised that I should go back and learn about them. So I did.

Aside

I’ve updat­ed my Speak­ing page to include more con­fer­ences, more videos, and a lit­tle on my speak­ing require­ments and pref­er­ences. I’m plan­ning to cut down on the num­ber of talks I give in 2014 (twelve is too many), but am always open to inter­est­ing offers and oppor­tu­ni­ties, so please get in touch if you’re organ­is­ing an event.
