Hide a div in a page and make it visible only on print bootstrap 3 MVC 5
提问by Ben Junior
There is a web page showing information to the user. If the user decides to print it I want to include additional information that is not required on the screen, but would be helpful when printed.
有一个网页向用户显示信息。如果用户决定打印它，我想包括屏幕上不需要的附加信息，但在打印时会很有帮助。
In order to implement this behaviour I was trying to make a divvisible only for printing. It hasn't worked though:
为了实现这种行为，我试图让一个div只对打印可见。但它没有奏效：
<div class="visible-print hidden-lg hidden-md hidden-sm hidden-xs">
I'm using Bootstrap 3 and wondered if there is an easy way to accomplish this?

I think the fact you've used
我认为你已经使用的事实
hidden-lg hidden-md hidden-sm hidden-xs
across the div means you've effectively hidden it across all viewports. To simply hide or show a div for print use the following:
跨越 div 意味着你已经有效地将它隐藏在所有视口中。要简单地隐藏或显示用于打印的 div，请使用以下命令：
<div class="hidden-print">content for non print</div>
<div class="visible-print">content for print only</div>
