Transparency (opacity) does not work

[enterit]

I've tried the example from README, it does not work - produces non-transparent background.

wmfocus --textcolor red --textcoloralt "#eeeeee" --bgcolor "rgba(50, 50, 200, 0.5)"

My i3 version:

$ i3 --version

Could you please clarify how/when opacity from CSS-like color should work?

wmfocus will make use of a compositor to get real transparency

What does 'compositor' mean? Are there environments where it is not supposed to work, or does 'compositor' have any limitations?

What's your desktop environment like? You need something like Compton or xcompmgr on xorg. In Wayland it should just work as is.

Oh, you're right, Compton fixed the issue. Thank you!

I use X11, and apparently I did not have any compositor.

I've also noticed that background opacity also affects text opacity. Is this by design? What do you think about an option to specify background and text opacity independently?

I think that'd be a cool option indeed, didn't consider that. I think it might be a fairly easy fix. Wanna try?
