I'm playing around with text-shadows to create a glow effect. What I'm seeing when animating is that the text-shadow will start from black and animate to the desired color and then animate back to black and ending on text-shadow: none. I'm wondering if there is a way to only animate the opacity of the text-shadow in rgba(). I'm sure it is obvious but I'm not seeing it. The code pen should help give an example. I have it paused to show the black text-shadow along with the desired text-shadow. Ideally, the text-shadow would begin animating from 0 opacity to .8 or whatever the opacity is set to in the glowShadow variable.
EDIT: You know, I just realized that I can still use fromTo with stagger to animate from a specific starting text-shadow to an ending text-shadow. I think I answered my own question here. Open to other ideas of course!
