Sometimes you just need to divide your page into different columns. With this plugin you just select a column shortcode and it will add the column to the page. You can also change the padding of each individual column from the UI.
There are 10 different column widths available from which you can make all combinations:
<ul>
<li>full width (1/1)</li>
<li>half (1/2)</li>
<li>one third (1/3)</li>
<li>two third (2/3)</li>
<li>one fourth (1/4)</li>
<li>three fourth (3/4)</li>
<li>one fifth (1/5)</li>
<li>two fifth (2/5)</li>
<li>three fifth (3/5)</li>
<li>four fifth (4/5)</li>
<li>one sixth (1/6)</li>
<li>five sixth (5/6)</li>
