I want to ask, did you consider the effect of Firefox after you finished the webpage? I'm usually tested after I'm done, because I used is Firefox, do not know how many of you here with Firefox, if a lot of words, I think you have to consider the browser effect of Firefox, do not only use IE detection is finished, China still has a lot of Firefox supporters. Of course, there are a lot of opera.
Firefox in Europe already occupies 50% of the market, Mozilla also appeared in China agent, some plug-ins are made by the people, notice Firefox bar, by the way, what browser you use?
As for opera, there is no need to worry, because opera 9.5 will support all the css,html and other syntax, which is currently in beta development, the latest version is 9.2. You may not believe that support all the CSS and other syntax, ie may not be able to do, foreign has a special browser Web site, all the grammar out of the test your website, a opera9.5 screenshot, the result is all through, ie6.0 currently can not be all through.
Sometimes in Alexa.com to see the site rankings, the results of the site's thumbnail also thought is not their own, usually used to use IE webmaster, do Web pages are all IE as the standard, as long as IE under the look of nothing on the line, but the Alexa thumbnail is based on Firefox's web page. So as long as the CSS + DIV to finish the page after the best with Firefox and Opera have a look. Oh．
This is my homepage http://www.ququhu.com in IE, FireFox, opera under the normal. Oh。 Also welcome everyone to add my QQ together with the standardization of the production of Web pages!
