这个要模拟得好的话必须得结合js才行的，光是那排字母就不光是点击，应该要支持手指在上面精确的滑动到某个字母范围，这个一时半会写不出来。你可以去网上找个常见的JQ滚屏插件来改动下自己琢磨。
简单的办法，ABCD..XYZ做成锚链接，加个js平滑滚动，样式你自己想办法完善，把A-Z那排链接display: block后设置成正方形方块，加个ul>li套上用定位放到左上角即可：
<!DOCTYPE html><html>
<body>
<style type="text/css">
h2:target{
background:#00C}
}
</style>
<body>
<a href="#L">L</a>
<a href="#W">W</a>
<p style="height:500px">占位区</p>
<h2 id="L">L开头的电话</h2>
<p>李四</p>
<p>黎明</p>
<p style="height:500px">占位区</p>
<h2 id="W">W开头的电话</h2>
<p>王波</p>
<p>网名</p>
</body>
</html>

看样子您这是想做一个简单的大屏应用，据我了解css3好像是不能直接操纵dom元素，好像有个select的方法，不过我不怎么了解，就不多说了。
我觉得可以用js方法实现，用localtion.href实现。具体如下:
<script>
var arr = ['#a', '#b', '#c'], num = 0
setInterval(() =>{
num = (num == arr.length - 1? 0 : num += 1)
location.href = arr[num]
}, 5000)
</script>
