Insert Back Button in Checkout

-- Joomla version -- : 3.4.8

Hello,

I want to add a go back button or link to the checkout page. I know that I should edit the file "Step" in Checkout (Menu>Display).
But, As far as I insert a link to this page, the page does not load any more. I add the link to the beginning or end of file. Should I insert HTML tags in this file and insert my link in the html part of file or I should do something else?

If possible, Would you tell me what should be the format of a correct button or link in this page? I use something like this:

<a class="btn btn-info" style="font-size: 12.16px; line-height: 1.3em;" href="#">Go Back</a>

I use protostar template and it supports Bootsrap. I have also enabled Bootsrap in Hikashop.


Thank you,
Hossein
