Is there a way to force IE or FF into a handheld mode for testing “@media handheld” stylesheets?

Question

Is there a way to force IE or FF into a handheld mode for testing \"@media handheld\" stylesheets?

Or, do I have to publish the pages and test with my Blackberry?

Answer 1

There's a simple way with media queries:

@media handheld, screen and (max-width: 500px) { /* your css */ }

This will make browsers that implement media queries use your handheld css when you resize the window to less than 500px.
