在调整页面大小时，我对填充切片图像有疑问。
在普通视图（100％）中，一切看起来都很好，但是当页面调整大小时，有时会出现白色细条，我真的不知道为什么会发生这种情况。只有我想到的是，在网页浏览器缩放页面后，它可能与轮廓分数有关。它发生在Chrome，Firefox，Safari，Edge，IE中，我想也可以在其他浏览器中使用。
这是在Chrome中调整为67％时的外观： click
该示例包含4个切片图像，其中每个图像的变换比例为0.96。

答案 0 :(得分：0)
这是因为语句calc((100% - 960px)/2)导致非整数值，因此浏览器应将其四舍五入为整数（正常数字不浮动数字），因此它将比您预期的小1px。您可以使用calc((100% - 959px)/2)轻松将效果更改为正常。
您可以轻松使用img和background-image，而不是使用background-size: cover;，这样即使在调整大小时也不会出现问题。
