-
배경을 요소 콘텐츠에 대해 고정합니다. 요소에 스크롤이 존재하면 배경은 콘텐츠와 함께 스크롤됩니다. 배경 페인트 영역과 배경 위치 영역은 테두리 틀이 아닌 스크롤 가능 영역을 기준점으로 삼습니다.

배경을 요소 자체에 대해 고정합니다. 요소에 스크롤이 존재해도 배경은 함께 스크롤되지 않습니다. 즉 요소의 테두리에 배경 이미지를 부착한 것과 같은 효과입니다.

<p>
There were doors all round the hall, but they were all locked; and when Alice
had been all the way down one side and up the other, trying every door, she
walked sadly down the middle, wondering how she was ever to get out again.
Suddenly she came upon a little three-legged table, all made of solid glass;
there was nothing on it except a tiny golden key, and Alice's first thought
was that it might belong to one of the doors of the hall; but, alas! either
the locks were too large, or the key was too small, but at any rate it would
not open any of them. However, on the second time round, she came upon a low
curtain she had not noticed before, and behind it was a little door about
fifteen inches high: she tried the little golden key in the lock, and to her
great delight it fitted!
