1. Description
모든 button Element들을 찾는다.
$(":button")은 CSS의 $( "button, input[type='button']" )과 같다고 한다.
속도 향상을 위해서는 직접 $(":button") Selector를 사용하기 보다는, pure CSS Selector를 사용한 후에 .filter(":button")을 사용하는 것이 좋다고 한다.
※ 자세한 내용은 「5. Reference」를 참고하세요.
2. Example
#1버튼을 클릭하면 button Element를 찾아 border-color, border-size를 변경한다. 버튼을 클릭할 때마다 해당 CSS가 토글된다.
