  22. HTML5 언어의 특징 • HTML5의 방향 • 마크업에 보다 의미를 부여, 스타일은 분리하도록 CSS3 활용 • 플러그인대신 웹 표준 적용하도록 SVG, MathML 지원 • 인터랙션 개발을 위해 자바스크립트를 지원 • 웹 애플리케이션의 개발을 위하여 다양한 API를 제공 • 특히 위치관련 및 오프라인 등 모바일 환경까지 고려한 API 제공

  23. (1) 강화된 마크업 요소 • 의미 부여가능한구조적 마크업 요소 • 페이지 단위의 문서 구조를 표현 • 다양하고 편리한 웹 폼(WebForm) 입력 기능 • 편리한 UI 개발을 위해 Form 기능 대폭 개선 • <input> 요소에 date, number, color 등 각종 type 추가 • 웹 미디어 기능의 강화 • <video> 요소와 <audio> 요소 • <canvas> 요소: 래스터 그래픽스그리기 기능 • SVG(Scalable Vector Graphics): 벡터 그래픽스 처리 • MathML 언어: 수식의 의미와 모양까지 표현 <header> <nav> <article> <aside> <section> <section> <footer>
