在 CSS 中停止生成不需要的滚动

Stop Generating Unwanted Scrolling in CSS

我从一个大约 animate.css 的网站上得到了很少的代码。我面临的问题是,当页面加载时,它会产生太多滚动。如果我使用 bounceInRight 或 bounceInLeft 生成左滚动或右滚动,当我使用 bounceInUp 或 bounceInDown 时它生成垂直滚动,当我最小化屏幕然后最大化该滚动时自动删除。这是我的 CSS 和 HTML

<div id="logo">
        <span id="a">
            <span class="dd animated bounceInUp">A</span>
        </span>

        <span id="leading">
            <span class="da animated bounceInUp">Leading</span>
        </span>


        <div>
        <span id="mep">
            <span class="zz animated bounceInUp">MEP</span>
        </span>

        <span id="integrated">
            <span class="zn animated bounceInUp">INTEGRATED</span>
        </span>
        </div>


        <div>
        <span id="solution">
            <span class="dr animated bounceInUp">Solutions</span>
         </span>


        <span id="provider">
            <span class="de animated bounceInUp">Provider</span>
        </span>


        </div>

    </div>

和CSS

带来很多高度的是你给 #logo 的 570px。你真的需要它吗?如果您不执行 position: absolute.

之类的操作,徽标内的文本块会为其父级提供自然高度

您的问题应该通过将 overflow-y: hidden; 添加到 #logo 来解决。
