Hello,
how to move the addtocart bottons to the bottom of the product box in one line in the category view?

Thanks for your help in advance!

Hi,

What you are asking is only possible using "flexbox" which is a newly introduced layout mode with CSS3 (more info: www.w3schools.com/css/css3_flexbox.asp)

This modification is 100% custom modifications (because you want to change how the things work/look) and unfortunately we don't provide free support or step-by-step instructions for custom coding modifications.

You may purchase premium support:

and let us take care this modification for you directly on your website though.

Regards.
Support
