OK! Classic case of RTFM on my end – after a bit of fiddling with CSS I have it.
For anyone else looking to do so:
functions.php
register_sidebar( array(
'name' => 'bottom-1',
'id' => 'bottom-01',
'before_widget' => '<div id="bottom-01">',
'after_widget' => '</div>',
'before_title' => '',
'after_title' => ''
) );
register_sidebar( array(
'name' => 'bottom-2',
'id' => 'bottom-02',
'before_widget' => '<div id="bottom-02">',
'after_widget' => '</div>',
'before_title' => '',
'after_title' => ''
) );
register_sidebar( array(
'name' => 'bottom-3',
'id' => 'bottom-03',
'before_widget' => '<div id="bottom-03">',
'after_widget' => '</div>',
'before_title' => '',
'after_title' => ''
) );
In your theme template (I am using geo-home.php)
<div class="section group">
<div class="col span_1_of_3">
<?php dynamic_sidebar( 'bottom-01' ); ?>
</div>
<div class="col span_1_of_3">
<?php dynamic_sidebar( 'bottom-02' ); ?>
</div>
<div class="col span_1_of_3">
<?php dynamic_sidebar( 'bottom-03' ); ?>
</div>
</div>
In your style.css
/* SECTIONS */
.section {
clear: both;
padding: 0px;
margin: 0px;
}
/* COLUMN SETUP */
.col {
display: block;
float:left;
margin: 1% 0 1% 1.6%;
}
.col:first-child { margin-left: 0; }
/* GROUPING */
.group:before,
.group:after { content:""; display:table; }
.group:after { clear:both;}
.group { zoom:1; /* For IE 6/7 */ }
/* GRID OF THREE */
.span_3_of_3 { width: 100%; }
.span_2_of_3 { width: 66.13%; }
.span_1_of_3 { width: 32.26%; }
/* GO FULL WIDTH BELOW 480 PIXELS */
@media only screen and (max-width: 480px) {
.col { margin: 1% 0 1% 0%; }
.span_3_of_3, .span_2_of_3, .span_1_of_3 { width: 100%; }
}
And as mentioned bu Guust, Set the Widget areas to 2 grid and ‘100’ not 100% and you are golden!
