Style display egenskab

Definition og brug

display Egenskaber indstiller eller returnerer elementets visningstype.

HTML-elementer er hovedsageligt "inline" eller "block" elementer: inline-elementer har både venstre og højre flydende indhold. Block-elementer fylder hele rækken, og der kan ikke vises noget indhold på deres venstre eller højre side.

display 属性还允许作者显示或隐藏元素。它类似于 visibility 属性。但是，如果设置 display:none，它会隐藏整个元素，而 visibility:hidden 意味着元素的内容将不可见，但元素会保持其原始位置和大小。

提示：如果元素是块元素，也可以通过 float 属性更改其显示类型。
