Web Components: concerns and opportunities

On the 21st of March I had the pleasure of participating in the Web Components panel at Edge Conf, and the privilege of giving the introduction to the panel. I’m a strong advocate of Web Components and it was great to be able to provide my opinion on them, alongside some real experts in the field, as well as hear questions and feedback from the community. The main concern which was raised is that, as developers create their own elements, some important considerations — accessibility not least — could get forgotten about.

Animating an Offset Value in SVG

In a little experiment I’m working on I recently found a bit of a show-stopping problem. After an APB on Twitter I got a rapid reply which helped me solve it, but it seems that I may be the first person to encounter this error, therefore it’s encumbent on me to document it. So this is that.

The reason for this is that all of these browsers support SVG filter effects, and CSS filter effects are basically shorthand functions that apply predefined configurations of SVG filters.

A simple explanation of High DPI screens

NB: This post is based on a briefing note I sent around at rehabstudio, the agency I work for. It’s intended to clear up some of the confusion around resolution on mobile devices with high DPI screens, especially when talking with clients, and is aimed at all roles in the agency, not only developers.

Video of some recent talks I’ve given

I’ve had a really busy year for public speaking, having had the pleasure of being invited to speak at ten events so far, from local grassroots meetings to professional conferences (with more to come). Not all of the talks are recorded but many are, so below I’ve selected a few videos from the last few months in the vain hope that you may find them interesting.
