HTML：

<div id="pedigree">
    <div id="parentwrap">
        <div class="parent">test</div>
    </div>
    <div id="childwrap">
        <div class="child">
            <p>Am. Ch. Kenai's Aldebaran</p>
        </div>
        <div class="child">
            <p>pAm. Ch. Santa Clara Del Viento</p>
        </div>
    </div>
    <div id="grandchildwrap">
        <div class="grandchild">Am. Can. Ch. Ryzann's Eclipse at Kenai</div>
        <div class="grandchild">Am. Ch. Timber Ridge's Abi of Kenai</div>
