Adjust size of checkbox label to grid column size

I'm using the <fieldset data-role="controlgroup" data-type="horizontal"> option for checkbox buttons because I want to hide my checkbox and highlight the button if its selected. Of course that works fine, but how can I size the label to the size of the grid column (using ui-grid-c).

<html lang="en"> 
   <head>
   <meta charset="utf-8">

Solution

You can just add CSS that make the label 100% width:

.ui-controlgroup .ui-checkbox label {
    width: 100%;
    margin-left: 5px; 
}

Updated FIDDLE

Note: you might not need the left margin if you are not actually lining up with regular checkboxes...
