可见性:隐藏的反面是可见性:可见。同样地，是否有相反的显示:没有?
当一个元素有display: none时，许多人都搞不清楚如何显示它，因为它不像使用visibility属性那么清楚。
我可以只使用visibility: hidden而不是display: none，但它不会产生相同的效果，所以我不会使用它。

在打印机友好的样式表的情况下，我使用以下:
/* screen style */
.print_only { display: none; }
/* print stylesheet */
div.print_only { display: block; }
span.print_only { display: inline; }
.no_print { display: none; }
I used this when I needed to print a form containing values and the input fields were difficult to print. So I added the values wrapped in a span.print_only tag (div.print_only was used elsewhere) and then applied the .no_print class to the input fields. So on-screen you would see the input fields and when printed, only the values. If you wanted to get fancy you could use JS to update the values in the span tags when the fields were updated but that wasn't necessary in my case. Perhaps not the the most elegant solution but it worked for me!

就像Paul解释的那样，没有与显示相反的文字:在HTML中没有，因为每个元素都有不同的默认显示，你也可以用类或内联样式等改变显示。
However if you use something like jQuery, their show and hide functions behave as if there was an opposite of display none. When you hide, and then show an element again, it will display in exactly the same manner it did before it was hidden. They do this by storing the old value of the display property on hiding of the element so that when you show it again it will display in the same way it did before you hid it. https://github.com/jquery/jquery/blob/740e190223d19a114d5373758127285d14d6b71e/src/css.js#L180
这意味着如果你将一个div设置为显示内联或内联块，然后隐藏它，然后再次显示它，它将再次显示为显示内联或内联块，就像之前一样
<div style="display:inline" >hello</div>
<div style="display:inline-block">hello2</div>
<div style="display:table-cell" >hello3</div>
脚本:
$('a').click(function(){
$('div').toggle();
});
请注意，即使div被隐藏(display:none)并再次显示之后，它的显示属性也将保持不变。
你可以使用display: block
例子:
<!DOCTYPE html>
<html>
<body>
<p id="demo">Lorem Ipsum</p>
<button type="button"
onclick="document.getElementById('demo').style.display='none'">Click Me!</button>
<button type="button"
onclick="document.getElementById('demo').style.display='block'">Click Me!</button>
</body>
</html>

最好的“相反”是将其返回为默认值，即:
display: inline
visibility:hidden将隐藏元素，但元素是他们的DOM。在display:none的情况下，它会从DOM中移除元素。
你可以为元素选择hide或unhide。但是一旦你删除它(我的意思是不显示)，它就没有明确的相反值。Display有几个值，如Display:block, Display:inline, Display:inline-block和许多其他值。你可以从W3C找到它。
