article

HTML Spec: “The article element represents a self-contained composition in a document, page, application, or site and that is, in principle, independently distributable or reusable, e.g. in syndication.”

article 是一個(gè)特殊的 section 標(biāo)簽,它比 section 具有更明確的語義, 它代表一個(gè)獨(dú)立的、完整的相關(guān)內(nèi)容塊。一般來說, article 會(huì)有標(biāo)題部分(通常包含在 header 內(nèi)),有時(shí)也會(huì) 包含 footer 。雖然 section 也是帶有主題性的一塊內(nèi)容,但是無論從結(jié)構(gòu)上還是內(nèi)容上來說,article 本身就是獨(dú)立的、完整的。

HTML Spec 中接著又列舉了一些 article 適用的場景。 “This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.”

當(dāng) article 內(nèi)嵌 article 時(shí),原則上來說,內(nèi)部的 article 的內(nèi)容是和外層的 article 內(nèi)容是相關(guān)的。例如,一篇博客文章中,包含用戶提交的評論的 article 就應(yīng)該潛逃在包含博客文章 article 之中。

問題是怎么才算“完整的獨(dú)立內(nèi)容”?有個(gè)最簡單的判斷方法是看這段內(nèi)容在 RSS feed 中是不是完整的??催@段內(nèi)容脫離了所在的語境,是否還是完整的、獨(dú)立的。

例子:

<article><header><h1>The Very First Rule of Life</h1><p><time pubdate datetime="2009-10-09T14:28-08:00"></time></p></header><p>If there's a microphone anywhere near you, assume it's hot andsending whatever you're saying to the world. Seriously.</p><p>...</p><footer><a href="?comments=1">Show comments...</a></footer></article><article><header><h1>The Very First Rule of Life</h1><p><time pubdate datetime="2009-10-09T14:28-08:00"></time></p></header><p>If there's a microphone anywhere near you, assume it's hot andsending whatever you're saying to the world. Seriously.</p><p>...</p><section><h1>Comments</h1><article><footer><p>Posted by: George Washington</p><p><time pubdate datetime="2009-10-10T19:10-08:00"></time></p></footer><p>Yeah! Especially when talking about your lobbyist friends!</p></article><article><footer><p>Posted by: George Hammond</p><p><time pubdate datetime="2009-10-10T19:15-08:00"></time></p></footer><p>Hey, you have the same first name as me.</p></article></section></article>

HTML5 中 div section article 的區(qū)別

article代表了一個(gè)文檔內(nèi)容的獨(dú)立片段,例如,博客條目或報(bào)紙文章,article標(biāo)簽的內(nèi)容獨(dú)立于文檔的其余部分。

article 是一個(gè)特殊的 section 標(biāo)簽,它比 section 具有更明確的語義, 它代表一個(gè)獨(dú)立的、完整的相關(guān)內(nèi)容塊。一般來說, article 會(huì)有標(biāo)題部分(通常包含在 header 內(nèi)),有時(shí)也會(huì) 包含 footer 。雖然 section 也是帶有主題性的一塊內(nèi)容,但是無論從結(jié)構(gòu)上還是內(nèi)容上來說,article 本身就是獨(dú)立的、完整的。

當(dāng) article 內(nèi)嵌 article 時(shí),原則上來說,內(nèi)部的 article 的內(nèi)容是和外層的 article 內(nèi)容是相關(guān)的。例如,一篇博客文章中,包含用戶提交的評論的 article 就應(yīng)該潛逃在包含博客文章 article 之中。

HTML5學(xué)習(xí)筆記簡明版(2):新元素之section,article,aside

article的主要作用是表示獨(dú)立性,即這篇文章脫離當(dāng)前網(wǎng)頁也有存在價(jià)值和意義,它可以有自己的一套header和footer這樣的結(jié)構(gòu)。

HTML5 里 section article 什么區(qū)別?header footer nav 該怎么理解?
