HTML5 hidden attributes are compatible with old browsers

Comments: HTML5 brings us a lot of simple but powerful HTML attributes: placeholder, download, and autofocus. Another new attribute is the hidden attribute. When a webpage element has the hidden attribute, it performs very similar to the display: none of CSS, And the element disappears without occupying any page space. The statement is simple:

The Code is as follows:
<Div hidden>
You can't see me!
</Div>
If you are using an old-fashioned browser that does not support this attribute, you can add the following code in CSS to support it ::

The Code is as follows:
* [Hidden] {display: none ;}

So why should we use the hidden attribute? The meaning is that it is more meaningful in semantics and enhances the readability of the Code. It is simpler than display: none in CSS!
