My CSS/LESS ribbon is displaying perfectly in Firefox, but encountering issues in Chrome when resizing the window.
At 100% zoom, everything looks good, but adjusting the zoom causes elements to become misaligned. To make it easier to troubleshoot, I've simplified the colors in the code snippet below.
NOTE: Make sure to set the CSS syntax to LESS and click RUN when using this code on Tinkerbin, otherwise the ribbon will not load properly :)
