モダンなCSS設計パターンを考える
The document summarizes Hiroki Tani's presentation at the QCon Tokyo 2014 conference on modern CSS architecture. Some key points discussed include: - Adopting modular approaches like OOCSS and SMACSS to separate structure from skin/style and improve maintainability. - Using techniques like BEM naming to further decouple CSS from HTML. - Developing reusable CSS modules and components with flexible modifiers. - Maintaining styleguides and pattern libraries for consistent front-end development.
