问题 I need some clarifiction on applying expressions in css. Some are suggesting don't go for using css expressions. Please clarify my doubt. thanks 回答1: You should not use CSS expressions since they are constantly evaluated on many user interactions across the web page.

问题 We are developing a web application that will be sold to many clients. There is already one client (a bank) which has decided that it will buy the product once it is ready. Unfortunately due to some miscommunication it came out rather late that the only browser they use is IE6. The application was already started with the thought in mind that it does not need to support anything else below IE7. The results are pretty good too - it's fully useable on IE7/FF/Opera/Safari. Haven't tested on

问题 I want to set the height of a div based on CSS expression. Basically it should be set as some % (say 90%) of the viewport width I tried the following, but is not working; height:expression(document.documentElement.clientWidth ? document.documentElement.clientWidth : window.innerWidth ); I am looking at a cross-browser way of doing this (IE7+, FF4+, Safari) 回答1: CSS expressions are not supported anywhere except IE (and are considered a bad idea even there). However, there isn't really another

问题 I have an old ASP web application for Time Sheet entry which is riddled with CSS expressions.

Which browsers still support CSS expressions

问题 From a blog: The basic idea with CSS expressions is that you will have calculation and dynamic values for properties in the CSS code, something that people have found very useful. A simple example can be implementing max-width behavior in IE 6: width: expression(document.body.clientWidth > 1100)? "1100px" : "auto"; This is the first time I read about them. It seems IE used to support CSS expressions but dropped them in IE8. What other browsers still use them and are they generally a good or

I read somewhere that CSS Expressions were deprecated and shouldn't even be used. I had never heard of them and decided to take a look. I found a code example that kept a floating element in the same spot on the screen, even if you scrolled. <html> <style> #fixed { position:absolute; left:10px; top:expression(body.scrollTop + 50 + "px"); background:white; border:1px solid red;} </style> <body> <p id="fixed">Here is some text, which is fixed.</p> <p> [many times: "stuff <br/>"] </p> </body> </html> This reminded me of the sites that had the "share bars" and stuff at the bottom of their pages.
