알게 된 문법

css

flex-basis (script에서는 flexBasis로 쓰인다)

플렉스 아이템의 초기 크기를 지정한다.(아마 초기 가로값)

JAVASCRIPT

.volume() /  .playbackRate()

.volume() : 미디어가 재생되는 볼륨을 설정합니다. 

.playbackRate() : 미디어가 재생되고있는 속도를 설정한다.

.currentTime() /  .duration()

.currentTime : 현재 재생시간 지정.

.parseFloat : 전체 재생기간 설정

.parseFloat()

문자를 실수로 변경한다.

timeupdate EVENT

오디오,비디오의 재생위치가 변경될때 timeupdate이벤트 사용

 

video[method]();

메서드 설정시 video.method() 뿐만 아니라 video[method]() 해도 동일함
