Mobile view – order detail (product images) and font size

Hi!

Is it possible to show the order detail(template:horizontal text) product images as its i shown on the desktop view in a row? Right now the product image shown on mobile as a column and the name and price goes below the image.
So it would be like:
|Product image| product name | product price

How can i change a component:text font size to a different value on mobile? I have added to the text some custom class then used the custom css tab but nothing happens.

Thanks in advance!

Best regards,
Norbert
