html - 视频 div 和文本 div 之间的空白

Question

我已经尝试了很多但没有任何效果，我在互联网上找到的所有内容都不适合我。我有一个名为“vidContain”的 div 内的视频，在这个 div 下方是另一个名为“about”的文本 div。 “vidContain”div 之间是一个未识别的空白，空白只有 4px 小。有人可以告诉我我做错了什么吗？

HTML 代码

<div class="nav">
            <ul>
                <li><a href="#vidContain">Home</a></li>
                <li><a href="#about">About</a></li>
                <li><a href="#services">Services</a></li>
                <li><a href="#blog">Blog</a></li>
                <li><a href="#contact">Contact</a></li>
            </ul>
        </div>

        <div id='vidContain'>
            <div id='vid'>
                <video loop muted autoplay poster="img/videoframe.jpg" class="fullscreen-bg__video">
                    <source src="video/finlay.mp4" type="video/mp4">
                    </video>
            </video>
            </div>
        </div>

        <div id="about">
            <p>Lorem ipsum</p>
        </div>

        <div id="services">
            Lorem ipsum
        </div>

        <div id='blog'>
            Lorem Ipsum
        </div>

Answer 1

此 id #vidContain 添加 property vertical-align: top; 并将此属性添加到 p margin:0;

还有两次关闭视频标签
