Quantity button with ecomposer app

[Lara14]

Hello everyone, 

I used the ecomposer app to create the individual product pages. However, there is a bug when I added the quantity button. Currently it looks like this: 

The minus button is not working, meaning when I click on it, the quantity only increases. 

Apart from this bug, I would also like to change the design of the quantity button. Where can I change the code in the ecomposer app and which code do I have to add so that the button looks like this:  

Thank you!

Hi @Lara14 could you please share with me your domain? I will check your quantity minus button issue in the backend.

About the question of changing the design of quantity button in EComposer, you can go to quantity element's present, then select your desirable style there.
