The b element now represents a span of text to be stylistically offset from the normal prose without conveying any extra importance, such as key words in a document abstract, product names in a review, or other spans of text whose typical typographic presentation is emboldened.
// b 元素现在描述为在普通文章中仅从文体上突出的不包含任何额外的重要性的一段文本。例如：文档概要中的关键字，评论中的产品名。或者代表强调的排版方式。
The i element now represents a span of text in an alternate voice or mood, or otherwise offset from the normal prose, such as a taxonomic designation, a technical term, an idiomatic phrase from another language, a thought, a ship name, or some other prose whose typical typographic presentation is italicized. Usage varies widely by language.
// i 元素现在描述为在普通文章中突出不同意见或语气或其他的一段文本，例如：一个分类名称，一个技术术语，一个外语中的谚语，一个想法等。或者代表斜体的排版方式。
