Can I change the width of the product list columns? Using blue_r theme

[kobra]

for mobile devices since the developer tools are no help

Where did you get the template "blue_r"
You have no responsive css files and your template is not responsive

The template is this one https://www.zen-cart.com/downloads.php?do=file&id=1893 I posted the template folder name not the "official" template name sorry about that. I did get the problem fixed however by adding

@media only screen
and (min-device-width : 320px)
and (max-device-width : 480px) {
#listCell0-0 {width:50%;}
#listCell0-1 {width:30%;}
#listCell0-2 {width:20%;}
}

To the main style sheet now everything is working on PC, tablet and mobile
Thanks for the help everyone
