WebKit's percent-sized floats bug: are there any workarounds?
I'm experiencing what appears to be a bug in WebKit's rendering of floating elements' width when they have margins. The following renders as one would expect in Firefox (3.6) and WebKit (Chromium 5.0): <div style="width: 100%; background-color: green;"> <div style="background-color: red; float: left; width: 50%;">n</div> <div s...
JavaScript displaying a float to 2 decimal places
I wanted to display a number with 2 decimal places. I thought I could use toPrecision(2) in JavaScript . However, if the number is 0.05, I get 0.0500. I'd rather it stay the same. What is the best way to do this? I can think of coding a few solutions, but I'd imagine (I hope) something like this is built in? Thanks Update See it o...

My question is say one is working w...

In the .NET framework, why are there PointF (float) and no "PointD" (double)?
Can anyone explain why, in the .NET framework, there are PointF structures (using the single-precision float type) and no "PointD" (using the double-precision double type)? Did they establish that such precision would never make sense in the System.Drawing namespace? Is there any other reason? ...

Clear inside div A is clearing the float of div B, which is outside of div A
This is a problem I've had several times when trying to create layouts with a sidebar. I made an example here: http://samutz.com/div.html #content has stuff inside it that needs to float and then clear within #content only. But when I try to clear inside #content, it clears the #sidebar's float as well, despite #sidebar being outside o...
