Brandon Zell “you can use Flexbox today” I’m not sure browser support is good enough to use flexbox for everything: http://caniuse.com/#search=flexbox April 21st, 201
• Layout • Paint • Composite align-content Changing align-content alters the geometry of the element. That means that it may affect the position or size of other elements on the page, both of which require the browser to perform layout operations. Once those layout operations have completed any damaged pixels will need to be painted and the page must then be composited together. align-items Changi
What to use for React styling?If you use React, then at some point you've thought about how to style your components. You were probably optimistic about finding the perfect approach... and then became dismayed when you slammed your face into this wall of style tools: Some are more popular than others, but for each one you'll find several experts recommending it. Even worse: it's not about picking

By Jamie Wong I won’t ramble in this post about the maintenance woe that is CSS, as others have said it better in the past. In particular, Christopher “vjeux” Chedeau sparked much of this discussion in his talk React: CSS in JS. Instead, I’d like to discuss Aphrodite, the inline styling solution we’ve developed at Khan Academy, the constraints that led to it, and its use in production today. Page
Avoid using HTML tags in CSS selectors E.g. Prefer .o-modal {} over div.o-modal {} Always prefer using a class over HTML tags (with some exceptions like CSS resets) Don't use ids in selectors #header is overly specific compared to, for example .header and is much harder to override Read more about the headaches associated with IDs in CSS here. Don’t nest more than 3 levels deep Nesting selectors i
React allows you to write styles inline and bypass a host of CSS shortcomings. Scope, dependency management, dead code elimination, these problems go away when adding your styles directly to components. But it's not all rainbows and unicorns. Things like theming and media queries become much more difficult when all your styles live directly on components. In this talk, we'll look at how to solve t
CSS selectors all exist within the same global scope. Anyone who has worked with CSS long enough has had to come to terms with its aggressively global nature — a model clearly designed in the age of documents, now struggling to offer a sane working environment for today’s modern web applications. Every selector has the potential to have unintended side effects by targeting unwanted elements or cla
25 January, 2013 MindBEMding – getting your head ’round BEM syntax Written by Harry Roberts on CSS Wizardry. Table of Contents Featured case study: NHS One of the questions I get asked most frequently is what do -- and __ mean in your classes? The answer is thanks to BEM and Nicolas Gallagher… BEM – meaning block, element, modifier – is a front-end naming methodology thought up by the guys at Yand
BEM was a transformative methodology in the world of CSS, but — when limited to the style sheet — it can only take us so far. The act of defining “blocks” forced us to treat our classes more semantically and methodically, clearly defining the component boundaries and relationships in our interfaces, and yet — as I’m sure the methodology’s originators at Yandex would be quick to point out — CSS is
本記事は2015年1月に開催されたHTML5 Conferenceでお話させていただいた、 「Beyond CSS Architecture」というCSS設計のセッションをフォローアップする記事です。 本記事では、このセッションの概要と補足、またセッション中に説明できなかった点などについて書いていきます。 ※当日のセッションの動画・スライドも公開されているので、文末からご覧ください。 CSSの難しさと、昨今のCSS設計事情 この近年、CSSにおける設計論というのが話題に出てくるようになりました。筆者も拙著『Web制作者のためのCSS設計の教科書』を書いたり、各地でCSS設計をテーマとした講演をする機会が多くありました。 CSSの難しさというのは、石本氏によるCSSコードの評価についての記事にも書かれているのですが、CSSは良くも悪くも厳格なコード規約は少なく、ただ宣言的に書けばいいだけです
2017年5月25日 CSS FlexboxとはFlexible Box Layout Moduleのことで、その名の通りフレキシブルで簡単にレイアウトが組めちゃう素敵ボックスです。前々からあった技術ですが、ブラウザーによって書き方が違ったり、仕様がころころ変わったりと、イマイチ一歩踏み出せない感があったFlexbox。しかしようやくモダンブラウザーでの利用に難がなくなり、実務にも充分使えるようになりました。今回はそんなFlexboxの魅力と使いドコロを、デモ付きで紹介していこうと思います! ↑私が10年以上利用している会計ソフト! 対応ブラウザー Can I use…で紹介されているように、現行のモダンブラウザーでは問題なく利用できます。ただし、Safari用に -webkit- のベンダープレフィックスが必要です。IEについては11から正式に対応。IE10にも対応していますが、書き方が
