Bug
Div-elements with background color and fixed positioning would get black borders at various zoom values in iOS 7.Fixed
We got rid of the black borders by applyingborder-radius: 1px;to the container elements which removed all black borders. The value is low enough to not be visible.
事實(shí)上,不止ios 7的瀏覽器上,win7下 FF32.0.1有時也出現(xiàn)過這個問題。
簡單來說就是,當(dāng)div為fixed position且有背景色或者背景圖的時候,會出現(xiàn)奇怪黑色線條。這時候用border-radius: 1px;可以暫時解決這個問題。
