Add to cart button : position and width with Google Chrome

Hi,

I have an issue with Add to cart button that displays differently with Google Chrome.

With Firefox ant I.E. it uses the standard css parameter "width: 220px !important;"

But with Google Chrome, it uses the css parameter "width: auto !important;", that is in "@media (max-width:65rem)" .

So the Add to cart button is beside the Quantity fields, instead to be under this one (see attached files).

How can I fix this, please ?

Best regards.
