Unicode Characters: A CSS Toolkit

Unicode characters offer a convenient way to add symbols and icons to your HTML or CSS (via pseudo-elements' content property). Here's how to effectively utilize them:

1. Essential Character Set Configuration:

For proper Unicode character display in your CSS, ensure both your HTML and CSS files specify UTF-8 encoding:

<code class="language-html"><meta charset="utf-8"></code>

<code class="language-css">@charset 'utf-8';</code>

2. The "Trigram for Heaven" as a Hamburger Menu Icon:

A quick and easy method for creating a hamburger menu icon is using the Unicode character "Trigram for Heaven" (☰). Here's how to implement it:

<code class="language-html"><nav class="site-nav">
  <ul class="site-nav-menu">
    <li><a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">lorem ipsum</a></li>
    <li><a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">lorem ipsum</a></li>
    <li><a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">lorem ipsum</a></li>

    <li><a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b">lorem ipsum</a></li>
  </ul>
  <a href="https://www.php.cn/link/93ac0c50dd620dc7b88e5fe05c70e15b" class="site-nav-icon">☰</a>
