CSS3 Gotcha: RGBA colours don’t work with spaces
February 21, 2011 (over a year ago)
I’m sure everyone knows about this but it surprised me at the time. If you have a space after ‘rgba’ in your colour statement, it won’t take effect.
This will work:
.mydiv { background: rgba(0, 0, 0, 0.5) }
This won’t work:
.mydiv { background: rgba (0, 0, 0, 0.5) }
(Note the space after ‘rgba’). Strange but true.
