Hi there!

I’m trying to use CSS `opacity` property, but I noticed that it’s working very unstable and only for `0` and `1` value, it is not working for float values.

Am I missing something here?

thanks in advance!

Unfortunately this property is not supported and quite erratic. I won’t recommend using it…
