我有个问题

这样用a嵌套img便签，是不是可以这样理解： 

img便签撑起来了a标签。a标签的宽和高就等于内部img 的宽和高

    ​    ​    ​    ​    ​<li class="pro-grid">

                        <a href="">

                            <div class="pic-box">

                                <span>机票</span>

                                <img src="image/jjzyx06.png" alt="">

                            </div>

                            <div class="word-box">

                                [赠自由行礼包] 上海/杭州/南京/合肥/宁波/徐州直飞日本东京/大阪…

                            </div>

                        </a>

                    </li>

                    <li class="more-grid">

                        <a href="">

                            <div class="pt">

                                <p>查看更多</p>

                                <P>机酒自由行产品</P>

                            </div>

                            <span class="iconfont">&#xe619;</span>

                            <ul>

                                <li>机票</li>

                                <li>酒店</li>

                                <li>机+酒</li>

                                <li>邮轮</li>

                            </ul>

                        </a>

                    </li>

这里a标签嵌套了所学的标签，嵌套了块级元素啊！很蒙

同学你好，行内元素一般是不建议嵌套块元素使用的，但是a标签有些特殊，它是超链接可以点击，因此好多时候需要点击的元素都用a标签嵌套使用，同学只需要记住这个特殊用法即可。

祝学习愉快！
