Apps How do some web sites disable the browser zoom?

[Ty Webb]

Go to m.cnn.com and the browser zoom seems to be disabled. Same with google's mobile site.

Go to yahoo's mobile site and the zoom is back.

Anyone know how this is done?

On my droid, the yahoo site does not provide zoom widgets.

I would surmize ...

if virutalPageWidth > screenWidth:
    enable page zooming
else:
    disable page zooming

Which, would allow any site to avoid zooming as long as it fits the devices screen width without a horizontal scroll bar. It would also explain the abberation of m.yahoo.com having zoom widgets on your device whereas mine does not.
