我使用 显示:块; 这对我很有用

当在Javascript中改变元素的显示时，在很多情况下，一个合适的选项来“撤销”element.style.display = "none"的结果是element.style.display = ""。这将从样式属性中删除display声明，将display属性的实际值恢复为文档样式表中设置的值(如果没有在其他地方重新定义，则恢复为浏览器默认值)。但更可靠的方法是在CSS中有一个类

.invisible { display: none; }

并从element.className中添加/删除这个类名。

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!

最好的“相反”是将其返回为默认值，即:

display: inline

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。

Display:unset将其设置回初始值，而不是之前的“Display”值

我只是复制了之前的显示值(在我的情况下display: flex;) 再次(在display non之后)，并且它过度尝试了display:none成功

(我使用display:none来隐藏移动和小屏幕的元素)
