Currently, I am working on an adaptive website where I have used em values for everything. However, I am facing discrepancies between Chrome and Firefox when it comes to interpreting em values. The website can be found at dev.morodeer.ru/stroymoidom and the issue is specifically with the metal bar featuring icons. When the width is around 670px, everything looks great in Chrome, but in Mozilla Firefox, the right edge gets cut off due to the centered wrapper being set to 90% width. Moreover, when both browsers are set to the same width, the metal bar appears smaller in Firefox, leading me to suspect that Firefox is using a smaller font size for calculations.
