Error when applying box-shadow style in CSS - Rails

Question

I would like to use the following box-shadow effect:

box-shadow: 0 1px 20px 0 rgb(231 238 242 / 8%);

It works well when directly applied to the element. But when placed in the .css file, it returns the error:

wrong number of arguments (1 for 3) for `rgb'

May I know what is the root cause please?

Answer 1

Maybe you need to use:

box-shadow: 0 1px 20px 0 rgb(231 238 242/8%);

The whitespace is problem.

Answer 2

In your box-shadow: 0 1px 20px 0 rgb(231 238 242 / 8%); the error in your coloring check your number of arugments for proper color:

You can try this: box-shadow: 0 1px 20px 0 rgb(231 238 242)
