I think it’s important to publish what you learn. There’s really no school for front-end development. You can’t go to a university for a JavaScript degree or a class about how browsers work. Most of us learn from blogs and Twitter. Early in my career, I learned a bunch of things whenever I worked on a project, but I never told other people about them. So my general advice is to publish what you learn, share with the community, and collaborate on projects that help move the community forward.

As Paul Irish put it, ‘Some of the finest research and writing about HTML & CSS & JS.’

Return to this. A good set of standards, including some things that I wasn't aware of and would like to implement.

Sounds stupid and listy but it's actually a good introduction to some of the more useful and practical pieces of the huge insane HTML5 Boilerplate (html5boilerplate.com).

"Compatibility tables for features in HTML5, CSS3, SVG and other upcoming web technologies."

How to make an background image scale without using a ton of JavaScript.

"I'd much rather rely on a subset of trusty old HTML than expend brain cells trying to remember the fake-HTML way to make something bold, or create a hyperlink. HTML isn't perfect, but it's an eminently reasonable humane markup language."

"A tool for visual layout development of YAML based CSS layouts." YAML stands for Yet Another Multicolumn Layout.

Detailed to the point of being almost unreadable!

Ugly "Browse..." buttons be gone!

"The need for these distinctions becomes moot, of course, when no secondary actions are present. Make sure you really need each secondary action on a form and don’t add them indiscriminately."

It's about time. But when will this actually become an official recommendation? When universally adopted? And will that adoption be as awful as the previous implementations?

Apparently "tags" is a reserved name in IE. For anything.

What works in which browsers.

Things always to remember when building a form.

When you need the code for a special character.
