Why my webpage is loading without CSS in Chrome and Safari?

I am developing a website with CSS and JS modifications.

While testing the website, it is working fine in IE-8 and Firefox browsers. But in Google Chrome and Safari the web page is loading without CSS.

I checked all the CSS paths on browser and all files are loading perfectly. But on the HTML page, these CSS files are not loading. So the w开发者_C百科ebpage is displaying the contents without any CSS properties.

What changes do we need to make in Chrome and Safari in order to make the website work perfectly.

As for Chrome, it probably the cache. Chrome assumes that he has cache of the css that's why he will not load it. Deleting cache helps in troubleshooting unloaded css problems . Same things happens on Safari base on my experience with it
