p 的内容必须是 flow content ( https://html.spec.whatwg.org/#flow-content
而 div 是 Palpable content ( https://html.spec.whatwg.org/#palpable-content 所以 p 里面不能放 div， 至于为什么 div 会被吐出来，就是因为根据 https://html.spec.whatwg.org/#concept-element-tag-omission 规则，元素结束标签在一些情况可以省略，而多余的结束标签会被忽略 p 的结束标签可以省略 https://html.spec.whatwg.org/#the-p-element Tag omission in text/html: A p element's end tag can be omitted if the p element is immediately followed by an address, article, aside, blockquote, details, div, dl, fieldset, figcaption, figure, footer, form, h1, h2, h3, h4, h5, h6, header, hgroup, hr, main, menu, nav, ol, p, pre, section, table, or ul element, or if there is no more content in the parent element and the parent element is an HTML element that is not an a, audio, del, ins, map, noscript, or video element, or an autonomous custom element. |

上面有一点错误，一个元素是 Palpable content 不代表不是 flow content，应该说 div 不属于 flow content ... https://html.spec.whatwg.org/multipage/dom.html#kinds-of-content

不对，研究了一下标准，上面说的内容错了
p 允许 Phrasing content div 不是 Phrasing content 但是，由于自动闭合规则存在，所以<p><div></div>是合法的，多余的</p>才是不合法的，标准似乎没有规定多余的</p>的处理方案，有一个方法就是给他补一个<p>，于是变成<p><div></div><p></p> |
