一、HTML頭部的重要性
HTML頭部是網頁中的一個<head>標籤，裡面通常包含了標籤、
標籤和標籤等。其中，標籤用於設置網頁的一些元數據，如字符集、關鍵詞、描述等。而<title>標籤則是用於設置網頁的標題，也是在瀏覽器中標籤頁上顯示的文本信息。</p><p>在編寫HTML頭部時，應當保持簡潔，只保留必要的標籤和元數據。這樣有助於提升網頁的加載速度和SEO排名，同時也方便搜索引擎對網頁的理解和分類。</p><h3><span
class=ez-toc-section id=25E425BA258C25E32580258125E625A025B725E525BC258F25E725BC259625E52586259925E7259A258425E5259F25BA25E6259C25AC25E825A7258425E525882599></span>二、樣式編寫的基本規則<span
class=ez-toc-section-end></span></h3><p>樣式編寫是指通過CSS來設置網頁元素的樣式效果，如字體、字號、顏色、邊框等。在進行樣式編寫時，有幾個基本的規則需要遵守：</p><ol>
<li>選擇器：CSS使用選擇器來選取要設置樣式的元素。選擇器可以是元素名、類名、ID名、屬性名等。</li>
<li>屬性和值：每個CSS樣式都由屬性和屬性值組成，屬性決定了要改變的樣式，而屬性值則決定了改變後的具體效果。</li>
<li>優先級：如果多個CSS樣式作用於同一個元素，那麼最終生效的樣式將是由優先級最高的樣式決定的。</li>
<li>繼承性：有些CSS屬性具有繼承性，即它們的效果可以被子元素繼承。比如，設置<code>body {font-size: 14px}</code>，那麼網頁中的所有文字都會繼承這個字號。</li></ol><h3><span
class=ez-toc-section id=25E425B8258925E32580258125E525AE259E25E425BE258B25E425BB25A325E725A02581></span>三、實例代碼<span
class=ez-toc-section-end></span></h3><pre>
<html>
<head>
<title>文本編輯器</title>
<meta charset="utf-8">
<style>
h1 {
text-align: left;
font-size: 28px;
color: #333;
}
p {
font-size: 16px;
color: #666;
margin: 10px 0;
}
.highlight {
background-color: #ffa;
}
</style>
</head>
<body>
<h1>這是原本的標題</h1>
<p>這是一段普通的文本，不帶任何樣式。</p>
<p class="highlight">這是一段高亮的文本，用CSS類名為其添加了樣式。</p>
</body>
</html></pre><h3><span
class=ez-toc-section id=25E5259B259B25E32580258125E525B0258F25E725BB2593></span>四、小結<span
class=ez-toc-section-end></span></h3><p>HTML頭部和樣式編寫是網頁製作中非常重要的環節，熟練掌握這些技能可以有效地提升網頁的質量和用戶體驗。我們需要按照規範化的思路和技巧，不斷探究和實踐。</p><div
