I am having a small issue with my isotope-packery layouts, where a very thin 1px or less line is appearing between certain items at some window sizes. Is there a way to eliminate this hairline gap?
Example: https://i.stack.imgur.com/juEsu.png (look between items 3 and 4)
I have a JSFiddle here to look at: http://jsfiddle.net/drawcard/akw6m9x1/ (resize the fiddle "window", so you can see the gaps)
// external js:
// http://isotope.metafizzy.co/beta/isotope.pkgd.js
//packery js (no need to copy this over if you have it included)
