HTML 檔案由以下元素構成：文件類型宣告元素元素（包含元資料）元素（定義標題）<body> 元素（包含可見內容） HTML 元素（定義內容類型）屬性（修改行為或外觀）註解（新增說明）腳本（新增互動性）樣式（定義視覺表現）</p></blockquote> <p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/202404/11/2024041104195362679.jpg" class="lazy" alt="html文件由什麼構成" ></p> <p><strong>HTML 檔案的組成</strong></p> <p>HTML（超文本標記語言）檔案是構成網頁的基礎。它定義了網頁的內容、版面和結構。 HTML 檔案由下列元素構成：</p> <p><strong>1. 文件類型宣告</strong></p> <p>每個 HTML 檔案都以文件類型宣告開頭，用於宣告檔案的 HTML 版本。例如：</p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class='brush:php;toolbar:false;'><!DOCTYPE html></pre><div class="contentsignin">登入後複製</div></div><p><strong>2. <html> 元素</strong></p> <p><html> 元素是 HTML 檔案的根元素，它包含了整個網頁的所有內容。 </p> <p><strong>3. <head> 元素</strong></p> <p><head> 元素包含了網頁的元數據，例如頁面標題、描述和連結。 </p> <p><strong>4. <title> 元素</strong></p> <p><title> 元素定義了網頁的標題，它將顯示在瀏覽器的標籤列中。 </p> <p><strong>5. <body> 元素</strong></p> <p><body> 元素包含了網頁的可見內容，例如文字、圖片和影片。 </p> <p><strong>6. HTML 元素</strong></p> <p>HTML 元素用於定義不同的內容類型，例如段落、標題、清單和連結。 </p> <p><strong>7.屬性</strong></p> <p>HTML 元素可以使用屬性來修改其行為或外觀。例如，<p> 元素的 align 屬性可以用來對齊段落。 </p> <p><strong>8. 註解</strong></p> <p>HTML 註解可以在 HTML 程式碼中加入說明，這些註解不會顯示在網頁上。註解使用  符號。 </p> <p><strong>9.腳本</strong></p> <p>HTML 檔案可以包含腳本，例如 JavaScript，用於在網頁上新增互動性。 </p> <p><strong>10. 樣式</strong></p> <p>HTML 檔案可以使用樣式表（例如 CSS）來定義網頁的視覺表現，例如字體、顏色和佈局。 </p><p>以上是html文件由什麼構成的詳細內容。更多資訊請關注PHP中文網其他相關文章！</p> </div> </div> <div class="wzconShengming_sp"> <div class="bzsmdiv_sp">本網站聲明</div> <div>本文內容由網友自願投稿，版權歸原作者所有。本站不承擔相應的法律責任。如發現涉嫌抄襲或侵權的內容，請聯絡admin@php.cn</div> </div> </div> <ins class="adsbygoogle" style="display:block" data-ad-format="autorelaxed" data-ad-client="ca-pub-5902227090019525" data-ad-slot="2507867629"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({});
