Hide Left Column on Tablet and Increase Centre Width

[motion2082]

Hey guys,

 

Looking to hide the left column on tablets and increase the centre column.

 

I have the css below to do it but not sure what media query in the global.css to look for

 

Can anyone help me out?

 

home page: 
body#index #center_column {width:951px}
body#index #right_column #left_column {display:none}

Category pages:

body#category #center_column {width:951px}
body#category #right_column {display:none}

Product pages:

body#product #center_column {width:951px}
body#product #left_column {display:none}
