Hi Sergiy,
Thanks for the reply. In my case, I do not want to change the background color of the whole group buttons as one, but each individual button if a certain criteria is met. As an example, I have three buttons called A, B and C and three local storage values called VarA, VarB and VarC.
What I would like to do is if VarA is empty then change background color of button A, if VarB is empty then change background color of button B, same thing for button C.
What would be the best way to accomplish this? I'm thinking through JavaScript, if so, what would I use to change background color of the button using JavaScript?
Can I call a CSS thorough Javascript?
Sincerely,
Alberto da Silva
