要在HTML中使用图标，您可以执行以下各项操作：

<!-- Method 1 -->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family for an entire HTML element -->
<!-- Define your icon fonts in your CSS font-family after your regular fonts  -->
<!-- This means that regular characters are default. Icons are a fallback  -->
<!-- Use UTF-8 characters directly in your HTML for improved human readability -->
<div class="rate"><p>I rate this movie ★★★★☆!!</p></div>

<!-- Method 2 -->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family for an entire HTML element -->
<!-- Define your icon fonts in your CSS font-family after your regular fonts  -->
<!-- This means that regular characters are default. Icons are a fallback  -->
<!-- Use entity codes in your HTML when UTF-8 support is uncertain -->
<div class="rate"><p>I rate this movie &#9733;&#9733;&#9733;&#9733;&#9734;!!</p></div>

<!-- Method 3 -->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family only for the icons but not the HTML elements that include them -->
<!-- Define your icon fonts in your CSS font-family before your regular fonts  -->
<!-- This means that icons are default. Regular characters are a fallback  -->
<!-- Use UTF-8 characters directly in your HTML for improved human readability -->
<p>I rate this movie <span class="icon">★★★★☆</span>!!</p>

<!-- Method 4 -->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family only for the icons but not the HTML elements that include them -->
<!-- Define your icon fonts in your CSS font-family before your regular fonts  -->
<!-- This means that icons are default. Regular characters are a fallback  -->
<!-- Use entity codes in your HTML when UTF-8 support is uncertain -->
<p>I rate this movie <span class="icon">&#9733;&#9733;&#9733;&#9733;&#9734;</span>!!</p>

<!-- Method 5 -->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family only for the icons and use a separate HTML tag for each icon -->
<!-- Define your icon fonts in your CSS font-family before your regular fonts  -->
<!-- This means that icons are default. Regular characters are a fallback  -->
<!-- Use UTF-8 characters directly in your HTML for improved human readability -->
<p>I rate this movie
    <span class="icon">★</span>
    <span class="icon">★</span>
    <span class="icon">★</span>
    <span class="icon">★</span>
    <span class="icon">☆</span>
    !!
</p>

<!-- Method 6 -->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family only for the icons and use a separate HTML tag for each icon -->
<!-- Define your icon fonts in your CSS font-family before your regular fonts  -->
<!-- This means that icons are default. Regular characters are a fallback  -->
<!-- Use entity codes in your HTML when UTF-8 support is uncertain -->
<p>I rate this movie
    <span class="icon">&#9733;</span>
    <span class="icon">&#9733;</span>
    <span class="icon">&#9733;</span>
    <span class="icon">&#9733;</span>
    <span class="icon">&#9734;</span>
    !!
</p>

<!-- Method 7-->
<!--- * * * * * * * * * * * * -->
<!-- Set a font-family only for the icons and use a separate HTML tag for each icon -->
<!-- Define your icon fonts in your CSS font-family before your regular fonts  -->
<!-- This means that icons are default. Regular characters are a fallback  -->
<!-- Use the 'content' style rule with a ':before selector' in your CSS -->
<p>I rate this movie
    <span class="icon icon-star"></span>
    <span class="icon icon-star"></span>
    <span class="icon icon-star"></span>
    <span class="icon icon-star"></span>
    <span class="icon icon-star-unfilled"></span>
    !!
</p>

如果您想选择方法7，则需要一些额外的CSS代码。这个CSS代码看起来像这样：

.icon-star:before {
    content: "\2605";
}

.icon-star-unfilled:before {
    content: "\2606";
}

Iconic ， Font Awesome 或 Glyphicons 等图标字体通常都使用方法7。这样做，以避免您必须从备忘单中复制粘贴特殊字符或强制使用HTML实体。

然而，这是一种有几个缺点的方法。首先，它需要支持:before CSS选择器以及对UNICODE字符使用转义序列。 IE6-7和certain versions of Webkit都没有提供这种支持。

另一个缺点是您必须为每个图标使用单独的HTML标记，每个标记对应于图标字体中的一个字符。与其他方法不同，方法7无法在HTML标记内显示多个图标。

其他方法也有其自身的缺点。方法1,3和5要求您从备忘单中复制粘贴字符或使用手段将字符本身放在代码中。您的代码编辑器可能无法显示该字符，或者如果图标字体使用该字符的非标准映射，则它可能会显示与图标字体中的字符不同的字符。

方法1,3和5还要求您的浏览器使用正确的编码来显示正确的字符。对于UNICODE字符，这并不像ASCII字符那样明显。但是，应该通过在HTML文档的<meta charset="utf-8" />中的某处添加元标记head来确保这一点。

方法2,4和6不要求您复制粘贴字符，但它会使您的代码对人类的可读性降低，并使代码的任何更改更容易出现人为错误。此外，您需要查找要使用的每个图标的HTML实体代码，或者您需要记住它们。虽然这同样适用于方法7中使用的类，但这些类比HTML实体代码更容易记忆。
