jquery ähnelt der unteren Navigationsvorschau der Baidu-Enzyklopädie. Der Code ist sehr einfach, daher wird es hier nicht viel Unsinn geben.

Rendering:

CSS 

 * {
      margin: 0;
      padding: 0
    }

    .wrap {
      width: 1000px;
      overflow: hidden;
      margin: 0 auto;
    }

    .content {
      width: 780px;
      float: left;
    }

    .slide {
      width: 200px;
      float: right;
    }
