I'm working with a background-color which should be 70% transparent, but I have many limitations:
- I can't use RGBa or HSLA (I'm getting the colors from a PHP Content Management System) as Hex
- The background color is dynamic - I can't use an image
- when I use opacity, the text is affected as well making it unreadable.
I'm sure the only option I have is changing my PHP code to generate RGBa colors instead, but asking, do you see any other solution?
