HTML Section 元素 表示包含在HTML文件中的功能性的獨(dú)立的部分,通常具有一個(gè)標(biāo)題,它不必代表它的更具體的語(yǔ)義單元。

舉個(gè)例子,導(dǎo)航菜單應(yīng)該包裝在一個(gè)<nav>元素中,但是一個(gè)搜索結(jié)果列表和一個(gè)地圖顯示及其控件沒有具體的元素,可以放在一個(gè)<section>。

內(nèi)容類別

Flow content, Sectioning content, palpable content.

允許的內(nèi)容

HTML元素

屬性

這個(gè)元素只包含全局屬性。

使用說明

  • 每一個(gè)都<section>應(yīng)該被識(shí)別出來,通常包括一個(gè)標(biāo)題(<h1>- <h6>元素)作為元素的一個(gè)子<section>元素。

  • 如果單獨(dú)聯(lián)合一個(gè)<section>元素的內(nèi)容是有意義的,請(qǐng)改用一個(gè)<article>元素。

  • 不要將該<section>元素用作通用容器; 這是為什么<div>,特別是當(dāng)切片只是為了造型的目的。經(jīng)驗(yàn)法則是一個(gè)部分應(yīng)邏輯地出現(xiàn)在文檔的大綱中。

<div>  <h1>Heading</h1>  <p>Bunch of awesome content</p></div>
