li不自动换行

*{padding: 0;margin: 0;}
.one{
    width: 300px;
    height: 300px;
    border: 1px solid #ccc;
}

.one ul {
    height: auto;
}
.one ul li{
    list-style: none;
    display: block;
}



<div class="one">
        <ul>
            <li>服务名称:XXX</li>
            <li>服务价格:XXX</li>
            <li>服务时长:XXX</li>
            <li>服务简介:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</li>
            <li>摘要:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX</li>
        </ul>
     </div>

li:nth-last-child(1),li:nth-last-child(2){
  height:auto;
  word-wrap:break-word;
  width:200px;//这个宽度根据自己实际情况定
}
