As you can see the search results contain around ten items. However, the result set is cut off at the bottom of the div of class div-summary

How can I modify the div-summary such that the search result set is shown?

.div-summary{
    text-overflow: ellipsis;
    white-space: nowrap;
    overflow: hidden;
    width: 25%;
    float:left;
    height: 100%;
    argin-top: 0px;
    margin-left: 2%;
    margin-bottom: 10px;
    display: inline;
}
