Confirmed W3C CSS automatically means cross-browser compatibility?

Question

I finally completed the working version of my first CSS site (thanks to some very useful suggestions on this forum) and checked the CSS. Before I go out and find (buy?) Another machine (I'm a Mac) to check IE, is it possible that valid CSS is really really valid for IE, as well as Firefox, Safari, which I have used to validate my code so far? Thanks Patrick.

Answer 1

No, W3C checks the CSS standard. Unfortunately, popular browsers (read: MSIE 6.0) are not very standard;)

Answer 2

I think it totally depends on how complex your CSS and layout is - if it's complicated at all, I would say no without hesitation. It is best to test this on other platforms.

You might want to look into BrowserCam - they take screenshots of websites in all major (and some small) browsers, and more expensive accounts allow you to use VNC to actually navigate to these platforms.

Answer 3

Not all browsers fully, correctly, and consistently implement all CSS features, especially when it comes to CSS2 or upcoming CSS3. W3Schools.com can help you as it lists which features are compatible with which browsers, although I'm not sure how far this information is given.

In the end, a small replacement for testing in all popular browsers. I would recommend installing Wine , Parallels , or VMWare and testing IE and Chrome . It might be nice to test Konqueror if this works on OSX.

If you install one of them - this is too much PITA (or if IE and Chrome will not work on Wine or Parallels - I'm not sure, and you do not have a copy of XP to install on VMWare), you may have a Windows friend that you could use. In the worst case, most libraries have Windows machines with which you could test.

Remember that the validator can only see if your syntax is correct. He cannot understand what layout you are trying to achieve, so that your pages are checked, will never be a sign that it works according to your desire in all browsers. It can do, but the check itself cannot tell you.

However, however, checking your pages would be a good idea. If there are no syntax errors, the chances for everything that works correctly grow.

To save web designers from this painstaking job of testing browser compatibility across browsers, there are several sites that offer this service. On these sites you can check the compatibility of your website in all necessary browsers.

"Is it possible that valid CSS is indeed valid for IE, as well as Firefox, Safari, which I have used to test my code so far?"

Really? How is it accepted in the browser? Yes.

Have a look? Not necessary.

If your page is simple enough and avoids all known IE incompatibilities, you're good to go. [We are trying to do this: just avoid weird things, use tables, accept restrictions for single-sized browsers.]

My suggestion is that you put the “Download Firefox” icon on your page and don’t worry about IE.
