How/where is this button to change

Hello,
my problem is that I do not find the correct file to this button (see atachment) to change. the file, which I have found is called "vmsite ltr.css-". This is located in /components/com_virtuemart/assets/css. I can change something in the file, but after the upload everything stays the same.

can U please help me?

regards

Hi,
first of all please check in Virtuemart settings if you have 'Using the VirtueMart CSS' option checked. If yes change it. It will disable default VM css loading. This option you will find in Configuration (Template tab). Then if you want to change it please edit css/vm.css located in our template folder.

Thanks so much, this was the solution! It was so quite easy ...!
