带有进度标记的php跟随另一个具有不同风格的进度标记的php

i have an issue regarding the tag..

file name: test.php:-

 <head>
 <style>

 progress[value] {
 width: 250px;
 height: 20px;
 -webkit-transform: rotate(270deg);
 }

 </style>
 </head>

 <progress max="100" value="80"></progress>

i copy the same code in another php file named test1.php but i change the width and height.. then, what happened is that, when i include both file in one php file to execute it, the output for both progress bar is the same.. the width is the same and so for the height..

anyone knows why?
