Worth Styling Zoomed Out?

This might be a poor question for this exchange but is it worth styling for zoomed out browsers? For instance, I can zoom chrome out to 25% and my navigation breaks, should I accom

Solution 1:

25%? I wouldn't worry about it unless you have a use case for your page where your users will be that far out.

Now, 75%-125%, you might consider it. Usually your page will work fine at other zoom levels. If it doesn't, it's likely because you have hard-coded something you shouldn't have. (For instance, you might assume that text on a certain line will never wrap. That isn't a good assumption. Different devices use different fonts, which could cause text to wrap in some cases.) In those cases, make sure to only set the sizes to specific values when needed. Let the page flow as much as possible.

Solution 2:

Probably not.

A good responsive design and sticky footer might work around this issue. That said, how many people zoom out this far?

See Marshall Roch's comment towards the bottom of that link - he says a small percentage have 1 zoom level off normal on facebook. So to zoom all the way to 25% seems quite extreme. I suspect any users who DID use that zoom level would be used to sites looking weird.
