flexible images CSS class

I placed 3 images in the header, one for the column, but I have problems with "responsive"
There is a CSS class that solve this problem? Otherwise, I can create it and where?

thank you

Please edit: /templates/gk_cloudhost/css/override.css and add at its end:

Code: Select all

.gkColorPriceTable dt img {max-width: 100%}


Remember to enable "CSS override" in template settings - advanced section.
