Responsive Rows

W3.CSS's grid system is responsive. The columns will re-arrange automatically depending on the screen size: On a big screen it might look better with the content organized in three columns, but on a small screen it might be better if the content were stacked on top of each other.

Class Description
w3-row Container for responsive classes, with no padding
w3-row-padding Container for responsive classes, with 8px left and right padding
w3-col Defines one column in a 12-column responsive grid

w3-col has the following sub classes:

Columns for small screens (typical smart phones):

Class Description
s1 Defines 1 of 12 columns (width:08.33%) for small screens
s2 Defines 2 of 12 columns (width:16.66%) for small screens
s3 Defines 3 of 12 columns (width:25.00%) for small screens
s4 Defines 4 of 12 columns (width:33.33%) for small screens
s5-s11  
s12 Defines 12 of 12 columns (width:100%). Default for small screens

Columns for medium screens (typical tablets):

Class Description
m1 Defines 1 of 12 columns (width:08.33%) for medium screens
m2 Defines 2 of 12 columns (width:16.66%) for medium screens
m3 Defines 3 of 12 columns (width:25.00%) for medium screens
m4 Defines 4 of 12 columns (width:33.33%) for medium screens
m5-m11   
m12 Defines 12 of 12 columns (width:100%). Default for medium screens

Columns for large screens (typical laptops and desktops):

Class Description
l1 Defines 1 of 12 columns (width:08.33%) for large screens
l2 Defines 2 of 12 columns (width:16.66%) for large screens
l3 Defines 3 of 12 columns (width:25.00%) for large screens
l4 Defines 4 of 12 columns (width:33.33%) for large screens
l5-l11  
l12 Defines 12 of 12 columns (width:100%). Default for large screens)

The classes above can be combined to create more dynamic and flexible layouts.

Each class scales up, so if you wish to set the same width for small, medium and large screens, you only need to specify the small class. And if you want the same width on medium and large screens, you only need to specify the medium class.

However, if you only use medium and/or large classes, the width will always transform to 100% on small screens.

Note: The number of columns should always add up to 12 for each row (6+6, 3+3+6, 9+3, etc)!

l10 s6

l2 s6

<div class="w3-row">
  <div class="w3-col l10 s6 w3-pink w3-center"><p>l10 s6</p></div>
