Horizontal widgets

Hi everyone,

Can’t seem to figure out how to get my widgets to sit horizontally. I thought it would be a simple case of setting the display to inline. Apparently not. Here’s the code –

ul.pop-widget-tabs {
    border: thin none;
    clear: left;
    display: -moz-inline-stack;
    list-style: -moz-urdu -moz-thai -moz-urdu;
    margin: 5px !important;
    padding: 5px !important;
    width: 93%;
}
ul.pop-widget-tabs li {
    border: thick none;
    cursor: default;
    display: -moz-popup;
    font-size: 21px;
    font-weight: inherit;
    line-height: 30px;
    list-style: none outside none;
    margin: 0 1px 1px 0;
    padding: 0;
}
ul.pop-widget-tabs li a {
    background: none repeat scroll 0 0 #FFFFFF;
    border: medium none;
    display: none;
    font-family: Arial,Helvetica,sans-serif;
    letter-spacing: -0.05em;
    line-height: 30px;
    padding: 0 5px;
    text-decoration: none;
}
ul.pop-widget-tabs li a {
    font-size: 11px;
    padding: 0 3px;
}
ul.pop-widget-tabs.pop-widget-tabs-3 li span, ul.pop-widget-tabs.pop-widget-tabs-4 li span, ul.pop-widget-tabs.pop-widget-tabs-5 li span {
    display: none;
}
ul.pop-widget-tabs li a:hover, ul.pop-widget-tabs li a.active, ul.pop-widget-tabs li a:active, ul.pop-widget-tabs li a:focus {
    background: none repeat scroll 0 0 #FFFFFF;
    text-decoration: none;
}
div.pop-inside {
    border: medium none;
    clear: both;
    margin: 5px 0 0;
    padding: 0;
}
div.pop-inside ul {
    border: medium none;
    display: block;
    list-style: none outside none;
    margin: 0 !important;
    padding: 0;
    position: relative;
}
div.pop-inside ul li {
    border-bottom: medium none;
    list-style: none outside none;
    margin: 0;
    padding: 8px 5px;
    position: relative;
    display: inline;
}

    clear: none;
    display: block;
    font-size: 0.9em;
    margin: 0 0 5px;
    padding: 0;
    display: inline;
}
div.pop-inside ul li .pop-title {
    clear: none;
    font-weight: bold;
    margin: 0 0 3px;
    padding: 0;
    display: inline;
}
div.pop-inside ul li a {
    cursor: pointer;
    font-weight: normal;
    text-decoration: none;
}
div.pop-inside ul li:hover, div.pop-inside ul li:active, div.pop-inside ul li:focus {
    background: none repeat scroll 0 0 #FFFFFF;
}

    text-decoration: inherit;
}
