The Hackernews Upvote Button is Unusable on Mobiles.

Even worse: you can't "retract" an accidentally placed down- or upvote.

It's pretty difficult to hit the vote buttons with a normal mouse/trackpad, too. Requires a lot of concentration.

Just zoom-in a bit, it works fine.

Sure CSS stylesheet for mobile devices would be nice.

CSS would not help much with the nightmare of tables that the HTML code of HN is.

I know. But it would be enough to increase the font-size and change the width of the tables.

A responsive version of hackernews would be not that difficult.
