i have table reason keeps overflowing width of container. works fine in chrome, in firefox refuses. site can found here: http://goo. gl/vkn5s i've tried using box-sizing: border-box; (with -moz prefix) on table, no difference (i don't see why make difference). images in table has margin, after removing margin still overflows container @ least 20px. table has width of 100% should fill container. td's have 50% width. 50% width more enough images fit (even image margin). i've read similar questions , of suggests removing padding/margin/border , not having display: block; (which don't have). i'm out of ideas. if use border-collapse:collapse remove it.
