Shop Design - "Go to previous page" Button

[BL28]

Hi 

I have added the below to my store to add "Back button". How can I move this from right side to left side of the page?

Online store > Theme > Sections > product-template.liquid file and add following code where you want to add Back button.

<a href="javascript&colon;history.go(-1)">back</a>

Thank you

Winnie
