My site has a 1 pixel gap in between DIVs which shows up in Safari (desktop and iPad), but does not show up in Firefox or Chrome. (www.ashleykirk.ca)
It's a responsive site so I'm using percentages. When I debug it, my left main content is measured at 939 px, and the right sidebar is measured at 349 px which adds up to 1288 px. But my max-width is set to 1289 px. Not sure why that is.
Any advice would be appreciated.
Your leftCol is 72.916666666667% of 1289 which in Chrome is rounding 939.895833333 up to 940px, however Safari seems to displaying it at it's intended value of 939px.
Personally I wouldn't do it like this. Either have breakpoints or I like using max-widths (which is supported to IE8) or re-calculate your widths.
1289 is an odd number, which can sometimes cause issues when trying to get a perfect balance.
Thanks for the feedback. I'll have to look into this further. I followed Ethan Marcotte's method for a responsive site using very long and precise percentages.
I do have breakpoints (using media queries). My understanding of a breakpoint is to change the layout via CSS depending on the size of the browser window. Is that what you mean?
I would never float two columns like that as it is just asking for trouble. Whenever you have to use more than 3 or 4 decimal points for a dimension you are asking a lot from browsers to get it right. Besides there's no such thing as half a pixel so browsers may round up or down to the nearest and you will be out by 1px - as in safari.
I would just float the first column and let the second column autofill the available space.

No gaps will be present as the remaining space space is always filled.
