11,717 PointsIs using RGBa the only way to specify an alpha channel?
For example, if you decide you want to add some transparency to a color that is already defined using hexadecimal, do you have to convert the value to RGBa?

7,105 PointsSorry Mark, but your answer is wrong. Please don't tell people that something cannot be done if you don't know for sure.
Corey: You can simply use "opacity" for your element. for example in this video, instead of h1 { font-size: 5.625em; color: rgba(255, 255, 255, 0.5); }
You can write:
h1 { font-size: 5.625em; color: rgb(255, 255, 255); opacity: 0.5; }
It's not the cleanest solution, but it does work.

3,726 PointsIt looks like Corey's question is, if an element is defined by #fff, can you add an opacity after it? Or, does the element have to be defined by rgb(255, 255, 255) in order to use an opacity? I was having some trouble understanding this as well. Are there any specific instances where #fff would be preferable to rgb(255, 255, 255)? Is there any difference other than semantics?
