HTML元素
这个HTML引用列表所有HTML元素,定义在HTML5或在之前的规范。把尖括号放置在HTML元素的两边,就构成了HTML标签 : 。
元素实体指定HTML文档如何应该建立,什么样的内容应该放置在一个HTML文档的哪些部分。
此页列出了所有的标准 HTML5 标签,而且浏览器可能支持陈旧及弃用的标签也会列出。在这里所介绍的 HTML5 元素通常都被认定为新的 HTML5 元素,即使其他标准元素也在 HTML5 认定为有效的。
在HTML文档内有一个元素被定义为一个开始标签。如果一个元素包含其他內容,它以一个结束标签结束,元素名称的前面有一个斜杠
. 有些元素不需要被封闭,如图像元素。這些元素也被称为空元素。HTML文件包含一个元素树状结构图。每一个元素都以各自的功能命名。举例来说: </code>元素代表文档的标题。</p>
<p style="border:0px;">下面按字母顺序列出HTML元素。</p>

<div>摘要大型语言模型的核心机制依赖于Transformer架构,该架构通过嵌入层将输入数据转换为向量形式,并结合位置编码以保留序列中单词的顺序信息。随后,这些向量进入多头自注意力层,能够同时关注输入序列的不同部分。自注意力层的输出经过残差连接和层归一化处理,以增强模型的学习能力和稳定性。接着,数据流经前馈网络进一步处理,最终再次通过残差连接和层归一化,得到编码器层的输出。模型性能高度依赖大规模和高质量</div>
