The app contains a list of songs that users will thumbs up or down (like YouTube comments) and the votes count is stored in firebase data base, all seems working fine but one thing i can't figure out is how to make the color of the buttons change when they get voted and stay changed when the user leaves and come back to the site, i know it should be simple but for some reason i can't figure it out!
Each user should see the song they up voted in green and the songs they down voted in red.
