ARA NOTE

<a href="#goAnchor">타이틀</a>

# Cannot resolve anchor #goAnchor
# Inspection info: Reports an unresolved last part of an URL after the # goAnchor.

위와 같이 작성했을때, 

아래와 같은 Warning 이 뜨는 경우가 있다.

Cannot resolve anchor #goAnchor
 Inspection info: Reports an unresolved last part of an URL after the # goAnchor.

이 스타일의 앵커는 거의 모든 브라우저에서 유효하지만 IntelliJ 에서는 warning 이 뜬다고한다.

이럴땐 간단하게 {} 로 감싸주면 해결된다.

Mac 사용중에 갑자기 트랙패드 제스쳐가 안먹힐 때가 있다.

그럴땐 당황하지말고, terminal에
