Move Scroll to top button

[macat]

UPDATE: I found where to do it, in the style sheet:
storefront/view/default/stylesheet/style.response.css on line 1465, change 25px to whatever you want. You also have to change:
storefront/view/default/stylesheet/style.css on line 2617 same thing, change 25px to the same thing as you did on the other stylesheet. I actually commented both out and put my own buttons on there. If you want to do that, you also have to modify:
storefront/view/default/common/head.tpl on line 53, comment this out:
<a id="gotop" href="#">Back to top</a>

I just started working on this store so nothing there yet.

I have searched the forum and looked around on the template pages but can't find where to change or remove the scroll to top button. Which page or css file do I need to modify please?
