日本語の組版において 「縦書きと横書きの選択肢がある」 ということは極めて自然ですが、 世界的にはマイナーな 書字方向でもあります。 一方、東アジアでは 縦書きを利用している国が 一定数あり、横書きの文化圏においても 縦書きを利用するケースが 「珍しい」というほど 少なくないことも事実です。 横書きの文字組が中心だった Webの世界において、 縦書きの知見を取り込み、 縦と横の文字組を自由に デザインできるようになることで、 Webデザインは更なる自由と 高い表現の可能性を 獲得できると言えます。 私たち『次世代Webブラウザの テキストレイアウトに関する 検討会(縦書きWeb普及委員会)』は、 縦書きレイアウトの 国際標準化活動を推進し、 縦書きWebコンテンツの 普及促進に取り組んでいます。 The concept of being able to choose between a h
Happy new year! As promised I thought I’d share a few of the Web animation things I’m looking forward to in 2017. I’m terrible at predicting the future (I used to be a believer in BeOS and VRML) so this is mostly based on what is already in motion. Specs: CSS transitions – this should move to CR status soon. Part of that involves splitting off a separate Timing Functions spec. That separate spec w

Software engineering principles, from Robert C. Martin's book Clean Code, adapted for JavaScript. This is not a style guide. It's a guide to producing readable, reusable, and refactorable software in JavaScript. Not every principle herein has to be strictly followed, and even fewer will be universally agreed upon. These are guidelines and nothing more, but they are ones codified over many years of
One of the prettiest features of ES6, it could easily win a beauty contest, if such a contest would be held. What many people don’t know is that the arrow function is not simply a form of syntactic sugar that we can use instead of the regular callback. As I like to explain it to the people who attend my trainings/workshops, arrow functions are this-less, arguments-less, new.target-less and super-l
Warning: This blog post is outdated. Instead, read section “Loading modules dynamically via import()” in “Exploring JavaScript”. The ECMAScript proposal “import()” by Domenic Denicola is at stage 4 and part of ECMAScript 2020. It enables dynamic loading of ECMAScript modules and is explained in this blog post. ECMAScript modules are static # ECMAScript modules are completely static: you must spec
