Show recent posts in multiple columns css code in wordpress?

Can someone help me to make recent posts to show up in 2 or 3 or 4 columns? May be some CSS or PHP code?

I use flexsqueeze theme that in the top feature sections supports multiple columns.

I also have Special Recent Posts plugin that has "Theme CSS" custom field within options that contains this code:

'/* The Recent Posts Container. */
div.srp-widget-container {
display : table;
clear : both;
}

/* The Widget Title. */
div.srp-widget-container h3.widget-title{
display : table-caption;
margin-bottom : 10px;
}

/* Single post entry box. */
div.srp-widget-singlepost {
padding : 0px 0px 10px 0px;
margin : 0px 0px 10px 0px;
border-bottom : 1px solid #CCCCCC;
}

/* The thumbnail box. */
div.srp-thumbnail-box {
display : table-cell;
vertical-align : top;
padding-right : 10px;
}

/* The content stuff box. */
div.srp-content-box {
display : table-cell;
vertical-align : top;
}

/* The excerpt. */
p.srp-widget-excerpt {
margin: 0px;
}

/* Single post title. */
h4.srp-widget-title {}

/* Single post title link. */
a.srp-widget-title-link {}

/* Thumbnail link. */
a.srp-widget-thmblink {}

/* Thumbnail image. */
img.srp-widget-thmb {}

/* The post date box. */
span.srp-widget-date {}

/* Stringbreak link. */
a.srp-widget-stringbreak-link {}

/* Stringbreak. */
span.srp-widget-stringbreak {}

'

Is there some CSS code for different columns to put in there?

Thanks
