用 vw 单位减去像素数量定义的网格列?
Grid column defined with vw unit minus a pixel amount?
我有一个网格grid-template-columns: 30vw 20vw 30vw;
我想从其中两个宽度中减去一个固定的像素数量,例如我希望第一列的计算宽度为 30vw - 1px
.
我想要的是(下面的代码不起作用):
grid-template-columns: calc(30vw-1px) 20vw calc(30vw-1px);
这样我就可以在网格外部获得一个边框,它仍然可以作为视口比例(不希望也以 vw 单位定义边框 - 希望它固定宽度为 1px)。
可能吗?
您的 calc()
参数无效。
你有这个:
grid-template-columns: calc(30vw-1px) 20vw calc(30vw-1px)
您需要这样做:
grid-template-columns: calc(30vw - 1px) 20vw calc(30vw - 1px)
来自 MDN:
The +
and -
operators must be surrounded by whitespace.
For instance, calc(50% -8px)
will be parsed as a percentage followed
by a negative length—an invalid expression—while calc(50% - 8px)
is
a percentage followed by a subtraction operator and a length.
Likewise, calc(8px + -50%)
is treated as a length followed by an
addition operator and a negative percentage.
The *
and /
operators do not require whitespace, but adding it for
consistency is both allowed and recommended.
