z-index is a CSS property that sets the stack order of specific elements. An element with greater stack order is always in front of another element with lower stack order. p Negative stack orders can also be used in the same manner. A negative value will appear behind a positive one. z-index only works on elements that have a position value (e.g. position: relative; ). Like all other CSS properties, it can be set with JavaScript as well with the following syntax:object.style.zIndex="1" == See also == *Z-order *Z-buffering 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Z-index」の詳細全文を読む スポンサード リンク
