<strong>:非常重要的元素

<strong> HTML 元素表示其内容具有很强的重要性、严重性或紧迫性。浏览器通常以粗体显示内容。

¥The <strong> HTML element indicates that its contents have strong importance, seriousness, or urgency. Browsers typically render the contents in bold type.

使用说明

¥Usage notes

<strong> 元素适用于 "非常重要，" 的内容，包括非常严重或紧急的事情（例如警告）。这可能是对整个页面非常重要的句子，或者你可以只是尝试指出某些单词与附近的内容相比更重要。

¥The <strong> element is for content that is of "strong importance," including things of great seriousness or urgency (such as warnings). This could be a sentence that is of great importance to the whole page, or you could merely try to point out that some words are of greater importance compared to nearby content.

通常，该元素默认使用粗体字体呈现。但是，它不应该用于应用粗体样式；为此目的使用 CSS font-weight 属性。使用 <b> 元素引起对某些文本的注意，但不指示更高的重要性级别。使用 <em> 元素标记具有重音强调的文本。

¥Typically this element is rendered by default using a bold font weight. However, it should not be used to apply bold styling; use the CSS font-weight property for that purpose. Use the <b> element to draw attention to certain text without indicating a higher level of importance. Use the <em> element to mark text that has stress emphasis.

<strong> 的另一个可接受的用途是表示段落标签，这些段落标签代表页面文本中的注释或警告。

¥Another accepted use for <strong> is to denote the labels of paragraphs which represent notes or warnings within the text of a page.

示例

<b> 与 <strong>

¥\ vs. <strong>

新开发者常常会感到困惑，为什么在渲染的网站上有如此多种表达相同内容的方法。<b> 和 <strong> 可能是最常见的混淆来源之一，导致开发者问“我应该使用 <b> 还是 <strong>？他们俩不都做同样的事吗？”

¥It is often confusing to new developers why there are so many ways to express the same thing on a rendered website. <b> and <strong> are perhaps one of the most common sources of confusion, causing developers to ask "Should I use <b> or <strong>? Don't they both do the same thing?"

不完全是。<strong> 元素用于更重要的内容，而 <b> 元素用于引起人们对文本的注意，但不表明它更重要。

¥Not exactly. The <strong> element is for content that is of greater importance, while the <b> element is used to draw attention to text without indicating that it's more important.

这可能有助于认识到两者在 HTML 中都是有效的语义元素，并且巧合的是它们在大多数浏览器中都具有相同的默认样式（粗体）（尽管一些较旧的浏览器实际上在 <strong> 下划线）。每个元素都旨在用于特定类型的场景，如果你想要粗体文本进行装饰，则实际上应该使用 CSS font-weight 属性。

¥It may help to realize that both are valid and semantic elements in HTML and that it's a coincidence that they both have the same default styling (boldface) in most browsers (although some older browsers actually underline <strong>). Each element is meant to be used in certain types of scenarios, and if you want to bold text for decoration, you should instead actually use the CSS font-weight property.

所附文本的预期含义或目的应该决定你使用哪个元素。传达意义就是语义的全部内容。

¥The intended meaning or purpose of the enclosed text should be what determines which element you use. Communicating meaning is what semantics are all about.

<em> 与 <strong>

¥\ vs. <strong>

更令人困惑的是，虽然 HTML 4 将 <strong> 定义为表示更强的强调，但 HTML 5 将 <strong> 定义为代表 "其内容非常重要。"，这是一个重要的区别。

¥Adding to the confusion is the fact that while HTML 4 defined <strong> as indicating a stronger emphasis, HTML 5 defines <strong> as representing "strong importance for its contents." This is an important distinction to make.

虽然 <em> 用于像口语强调一样改变句子的含义（"我爱胡萝卜" 与 "我爱胡萝卜"），但 <strong> 用于赋予句子的某些部分额外的重要性（例如，“警告！这是非常危险的。”) <strong> 和 <em> 都可以嵌套来分别增加相对重要性程度或强调强调。

¥While <em> is used to change the meaning of a sentence as spoken emphasis does ("I love carrots" vs. "I love carrots"), <strong> is used to give portions of a sentence added importance (e.g., "Warning! This is very dangerous.") Both <strong> and <em> can be nested to increase the relative degree of importance or stress emphasis, respectively.
