A very novel way to hide text with CSS style sheets

Explain why existing several CSS hidden text methods are flawed and how new methods are made up. Practical, but this method is quite novel.

A flaw in 1.display:none;

Search engines may think that hidden text is junk information and ignored

Screen readers (Programs that read screen content designed for visually handicapped people) ignore hidden text.

2. Defects of Visibility:hidden;

This one should be familiar with the hidden content will occupy him should occupy the physical space

3.overflow:hidden; a more reasonable method

.texthidden { display:block;/*统一转化为块级元素*/ overflow: hidden; width: 0; height: 0; }

As the above CSS shows the method, the width and height set to 0, and then more than partially hidden, will make up for the above one or two methods of defects, but also achieve the purpose of hiding content.
