Hi richnyc30
Not sure which Shape5 template are you using so I make a sample here:
1/ Create 'custom.css' file in template folder: [root]/templates/s5_yourtemplate/css/ if this file doesn't exist now
2/ Add custom CSS for S5 Vertical accordion module:
#s5_va_accordion .s5_va_inactive {
background: #e2ecfc !important;
}
This code is used to change background color of inactive tab. You can add your own custom then.
