如何制作小标题？

Question

我是初学者，正在学习 HTML，我很难制作一个像本网站顶部的小标题或下图中的小标题。这是我到目前为止尝试过的 HTML：

<header class="header">

  <div class="dropdown_menu">

    <div class="small_header">

      <ul id="menu-small-menu" class="small_menu">

        <li id="menu-item-10429" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-10429">12 Royal Street California USA</li>

        <li id="menu-item-6305" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-6305">001-122-134-555</li>

        <li id="menu-item-6211" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-6211">[e-mail]</li>

      </ul>

    </div>

  </div>

</header>

欢迎来到SO！如前所述，请发布一个最小的、可重现的示例，以便我们找出如何帮助您。此外，您需要准确指出您遇到的问题。如果你只是想要.smallHeader一行，基本的 CSS 可以是：.smallHeader {&nbsp; &nbsp; font-size: small; /* small compared to 'medium' (which is the default, avg. 16px) */&nbsp; &nbsp; line-height: 1.2; /* (without 'px') fairly common default. Will also center text vertically */&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; /* A higher value will increase top/bottom spacing of text, but */&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; /* instead you can also use 'padding' to create T/B spacing */MDN：字体大小，&nbsp;MDN：行高，&nbsp;MDN：填充但是请注意，使用padding顶部/底部间距的长文本可能会有偏好，因为当行在较小的屏幕上换行时，每个换行将具有相同的line-height（通常不是预期的效果）而不是围绕文本块的间距。这只是创建小标题行的众多方法之一....使用您的代码的片段line-height和一些额外的代码来显示和之间的区别padding。在“全页视图”中运行代码段并调整浏览器大小...ul,li {&nbsp; &nbsp;padding: 0; list-style-type: none /* override CSS defaults */}ul {&nbsp; &nbsp; margin: 0 /* ditto */}.smallHeader {&nbsp; &nbsp; font-size: small; /* small compared to 'medium' */&nbsp; &nbsp; line-height: 1.6; /* demo, default is approx. 1.2 */&nbsp; &nbsp; /* eye-candy */&nbsp; &nbsp; background-color: grey; color: white;&nbsp; &nbsp; text-align: center;}li.menu-item {&nbsp; &nbsp; display: inline; /* default is 'list-item'. This makes it go horizontal */&nbsp; &nbsp; /* eye-candy */&nbsp; &nbsp; padding: 0 1em; /* some L/R spacing between menu-items */}.bigHeader {&nbsp; &nbsp; font-size: x-large; /* extra large */&nbsp; &nbsp; padding: 1em 0; /* T/B padding instead of line-height *//* eye-candy */&nbsp; &nbsp; background-color: black; color: white;&nbsp; &nbsp; text-align: center;}[class^="test"] { background-color: rgba(0,0,0,.1) } /* classnames starting with "test" */.test-lh { line-height: 1.5em }.test-pd { padding: 1.5em }<header>&nbsp;<div class="smallHeader">&nbsp;&nbsp; &nbsp; <ul id="menu-small-menu" class="small_menu">&nbsp; &nbsp; &nbsp; &nbsp; <li id="menu-item-10429" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-10429">12 Royal Street California USA</li>&nbsp; &nbsp; &nbsp; &nbsp; <li id="menu-item-6305" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-6305">001-122-134-555</li>&nbsp; &nbsp; &nbsp; &nbsp; <li id="menu-item-6211" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-6211">[e-mail]</li>&nbsp; &nbsp; &nbsp; </ul>&nbsp;</div>&nbsp;<div class="bigHeader">extra large text</div></header><div class="test-lh">&nbsp; &nbsp; <p>Lorem ipsum dolor sit amet, exerci dolorem est ad.

您可以使用display:grid轻松实现这一点。如果你有这样的 html 文件；HTML<header>&nbsp;<div class="smallHeader">&nbsp;&nbsp; &nbsp; <ul id="menu-small-menu" class="small_menu">&nbsp; &nbsp; &nbsp; &nbsp; <li id="menu-item-10429" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-10429">12 Royal Street California USA</li>&nbsp; &nbsp; &nbsp; &nbsp; <li id="menu-item-6305" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-6305">001-122-134-555</li>&nbsp; &nbsp; &nbsp; &nbsp; <li id="menu-item-6211" class="menu-item menu-item-type-post_type menu-item-object-page menu-item-6211">[e-mail]</li>&nbsp; &nbsp; &nbsp; </ul>&nbsp;</div>&nbsp;<div class="bigHeader"></div></header>CSSheader{display:grid;grid-template-columns: auto;}这使您能够在标题中创建一个网格，并确保标题中的每个 div 都占用一行空间！然后，您还可以修改页眉中两个 div 的高度、颜色……。
