Mobile compatiblity while generating web pages

HI,

I am writing a web application which has a portal page that should work properly in desktop browser and mobile devices. When i write the html/css/javascript开发者_JS百科/jsp content, i want to make sure this code works properly in both desktop browsers and mobile browsers. I can test desktop browser functionality with the development server itself.

To make sure it works well with mobile also, is there any simulator where in if i paste my code, i can see the output in that simulated mobile browser?
