Google's ie9.js ie8.js ie7.js resolves conflicts between IE5, IE6, IE7, and IE8 and W3C standards

If you use IE5, IE6, and IE7 to browse the same webpage, the effect may be different. This is because the CSS resolution selector is different between them or is caused by errors and individual bugs. To solve these errors and bugs. We have to find a solution that balances them. For example, if the png transparency issue cannot be displayed in IE5 or IE6, we may use CSS hack or introduce external JavaScript. For example, the method I mentioned previously used with pngfix is to call external JavaScript to solve the png transparency problem in IE5 and IE6. Of course there are more methods. Now there is a more perfect method that is compatible with CSS selector parsing of IE5, IE6, and IE7. That is: ie7-jsie7-js is a JavaScript Library (a JS library that resolves conflicts between IE and W3C standards ), make Microsoft's Internet Explorer act like a Web-compatible browser. It supports more W3C standards and CSS2 and CSS3 selectors. It fixes many HTML and CSS problems and makes transparent PNG correctly displayed under IE5 and IE6. At present, this ie7-js version: 2.0 beta 3 usage: directly reference the js file on the Google Code server. <! -- [If lt IE 7]> <script src = http://www.bkjia.com/uploads/allimg/131201/01450241F-0.png "; </script> <!
