Master page issue in asp.net after publishing

I am facing a unique issue with my application.

In my master page, I have few CSS scripts tag and some coding to display some text on the Master page and everything is working fine.

but when I am publishing the same开发者_StackOverflow website, on same server and opening it on the same browser, I can see that all the CSS which I have written on the Master Page is vanished.

I have no idea what happened...

The code snippet you provided indicates the text is white. White text on a white background isn't the problem, is it?

We could help you better if you could provide a more complete code sample.
