我有一个用CSS制作的对角页面，使用线性渐变。
background: -webkit-linear-gradient(-63.5deg, #999cdb 50%, #f6bdbd 50%);
这将从右上角到左下角形成一条对角线。问题是，当用户点击我的登录/注册表单时，模型会更改其高度。因此，对角线不会重新计算其定位。线性渐变重复，这只是丑陋。
有没有人知道如何让它重新计算其定位？我已经尝试了很多但没有成功。感谢。

我认为如果您的宽度或高度可以改变，固定度将无法解决。你需要它相对于大小。
可以使用：
background: -webkit-linear-gradient(top left, #999cdb 50%, #f6bdbd 50%);
background: -moz-linear-gradient(top left, #999cdb 50%, #f6bdbd 50%);
background: -o-linear-gradient(top left, #999cdb 50%, #f6bdbd 50%);
background: linear-gradient(to bottom right, #999cdb 50%, #f6bdbd 50%);
