How to edit WhatsApp text color in code editor?

[GustavoAlves]

O tema que coloquei já vem com o whatsapp e não sei onde vou no editor de código silencioso, alguém poderia me ajudar?

This location in the inspect changes the code, but the location there is (index) where would that be?

Hello @GustavoAlves 

You can follow these steps: 
1. Go to Online Store->Theme->Edit code

2. Open your theme.liquid file, paste the below code before </body>

<style>
.sticky-chat .chat-text span {
	background-color: #f0f5fb !important;
 }
</style>

I hope the above is useful to you.

Kind & Best regards,
