CSS makes the Textarea text box adaptive to the browser width

Source: Internet
Author: User

In the CSS tutorial of (www.bkjia.com), the CSS enables the Textarea text box to adapt the browser width. The CSS here is actually a disguised JavaScript, because the expression in CSS is changed only when JavaScript is called, the actual execution is still JavaScript code, but this method of calling will reduce the efficiency, please use it with caution.

<Title> text box adaptive browser width </title> <br/> <body> <br/> <textarea style = "width: expression (document. body. clientWidth-20) "> 123 </textarea> <br/> </body> <br/> <center> for more tutorials, visit: <a href = http://www.bkjia.com/target = _ blank _ fcksavedurl = "http://www.bkjia.com/target = _ blank"> http://www.bkjia.com/</a> </center>

Tip: the code can be modified before running!
