html - レイアウトの問題、一部固定幅、一部エラスティック

Answer 1

Apply the background-image only to the wrapping div.

Alternatively, if the center and sides need to have different images, give the center div a non-transparent background-color as well.

Also, you could fake it by using multiple background-images. Demo

Keep in mind this won't work in old versions of IE, but something as non-essential as background transparency can be excepted as graceful degradation.

Answer 2

中央の div に不透明な背景を配置するだけで、他の背景が透けて見えなくなります。
