问题 I just tried to write the following rule to style the input placeholder for browsers that support it: #main input::-webkit-input-placeholder, #main input:-moz-placeholder { color: #888; font-style: italic; } The problem is that the rule isn't applied. However, if I break it up like this instead it works just fine: #main input::-webkit-input-placeholder { color: #888; font-style: italic; } #main input:-moz-placeholder { color: #888; font-style: italic; } Why can I not group browser-specific

问题 How can we distract our clients from using IE6. We know IE6 is not a good standard-compliant browsers; has many issues. How to satisfy clients so that they do not use IE6?

问题 I have a problem with the scrollTo function when it is called by a jQuery animate function. Here my code: $("#button").click(function(){ $("body").animate({scrollTop: 1400},"slow"); }); When I click the button, the flicker appears before the body scrolling. For example, I'm on (scroll position) 1000, and when I clicked the button the following happened: page/image on (scroll position) 1400 appears, it looks like I have already gone to (position) 1400 then it moves again to (position) 1000,

问题 I am very new to GWT and I started to take a look at it after I jumped into the Vaadin world. Reading this from the wiki: https://code.google.com/p/google-web-toolkit-doc-1-5/wiki/FAQ_DeferredBindingDefinition When the GWT Compiler compiles your Java application, it determines all the different "idiosyncrasies" that it must support, and generates a separate, tightly streamlined version of the application for that specific configuration. For example, it generates a different version of the
