After looking at so many examples of accordion effects on the Internet, I thought they were all too cumbersome to stand up to, so I simply wrote a simpler one myself.
The following is HTML
<span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">id</span><span style="color: #0000ff;">="accordion"</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">ul</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="accordionTitle"</span><span style="color: #0000ff;">></span>1<span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="accordionMain"</span><span style="color: #0000ff;">></span>222<span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="accordionTitle"</span><span style="color: #0000ff;">></span>2<span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="accordionMain accordionActive"</span><span style="color: #0000ff;">></span>222q<span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="accordionTitle"</span><span style="color: #0000ff;">></span>3<span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="accordionMain"</span><span style="color: #0000ff;">></span>222dd<span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"><</span><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="accordionTitle"</span><span style="color: #0000ff;">></span>3<span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></</span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></</span><span style="color: #800000;">ul</span><span style="color: #0000ff;">></span> <span style="color: #0000ff;"></</span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span>
JS code
ul{list-style-<span style="color: #000000;">type: none;padding: 0px;margin: 0px;} #accordion ul li{</span><span style="color: #0000ff;">float</span><span style="color: #000000;">:left;display: inline;} .accordionTitle{width:20px;height:100px;border:1px solid #</span>000000;background-color:#FFCCFF;writing-mode:lr-tb;margin:1 auto;line-height:24px;<span style="color: #0000ff;">float</span><span style="color: #000000;">:left;} .accordionMain{margin</span>-left: 22px;display:none;width:100px;height:100px;background-color: blue;border:1px solid #000000<span style="color: #000000;">;} .accordionActive{display:block;}</span>
Just paste and copy to run, but don’t forget to add the jQuery package
