CSS Display(显示) and Visibility(可见性)_html/css_WEB-ITnose
如何设置一个元素是否显示,visibility属性指定一个元素应可见或隐藏。
隐藏元素 - display:none或visibility:hidden
隐藏一个元素可以通过display属性设置为"none"或"hidden"属性的可见性。但是,请注意这两种方法产生不同的结果
visibility:hidden可以让您隐藏某个元素,但它仍然需要像以前一样的空间。该元素将被隐藏,但仍然会影响布局。
h1.hidden {visibility:hidden;}
display:没有隐藏的元素,它不会占用任何空间。元素将被隐藏,但页面会显示:
h1.hidden {display:none;}
CSS Display - 块和内联元素
块元素是一个元素,占用了全部宽度,在前后都是换行符。
块元素的例子:
内联元素只需要必要的宽度,不强制换行。
内联元素的例子:
如何改变一个元素显示
可以更改内联元素和块元素,反之亦然,可以使页面看起来是以一种特定的方式组合,并仍然遵循web标准。
下面的示例显示为内联元素的列表项:
li {display:inline;}
Copy after login下面的示例是把span元素作为块元素
span {display:block;}
Copy after login注意:变更元素的显示类型看该元素是如何显示,它是什么样的元素。例如:一个内联元素设置为display:block是不允许有它内部的嵌套块元素。.
