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.
事实上,不止ios 7的浏览器上,win7下 FF32.0.1有时也出现过这个问题。
简单来说就是,当div为fixed position且有背景色或者背景图的时候,会出现奇怪黑色线条。这时候用border-radius: 1px;
可以暂时解决这个问题。
