Add new comment to 2 slupce přes wysiwyg

skusal som to podla tohoto postupu, pri vytvarani templejtu kliknrm na "edit HTML source" a vlozim tam tento layout:

<style>
.newspaper
{
-moz-column-count:3; /* Firefox */
-webkit-column-count:3; /* Safari and Chrome */
column-count:3;
}
</style>
<p><b>Note:</b> Internet Explorer 9, and earlier versions, does not support the column-count property.</p>
<div class="newspaper">
Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat.
</div>

Ale nejko to nefunguje. Nepusti <style>. Takze neviem ako vkladat sablonu v CSS3.
