html5中常用的結構標簽
article 文章
header 頭部
nav 導航
section 區域
aside 側邊欄
hgroup 區塊的相關資訊
figure 定義一組內容及標題
figcaption 定義figure元素的標題
footer 底部
dialog 對話框
使用習慣：
header/section/footer > aside/article/figure/hgroup/nav > div
embed可插入flash檔案，但flash已經逐漸被淘汰，不建議使用
meter狀態標簽，可以定義電壓
optimum是標準狀態
low與high之間呈現綠色，其余呈現黃色
<meter value=”220” min=”20” max=”380” low=”200” high=”240” optimum=”220”></meter>
自動計算百分比
<meter value="0.75">75%</meter>
有步長的進度條
<progress value="30" max="100"></progress>
不斷加載的進度條
<progress max="100"></progress>
datalist為input定義下拉串列
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> <input placeholder="請選擇手機品牌" list="phoneList"> <datalist id="phoneList"> <option value="iphone">iphone</option> <option value="samsung">samsung</option> <option value="huawei">huawei</option> <option value="oppo">oppo</option> <option value="htc">htc</option> </datalist> </body> </html>
details定義元素的詳細內容，配合summary
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> <details> <summary>HTML5</summary> <p>HTML5是構建Web內容的一種語言描述方式，HTML5是互聯網的下一代標準，是構建以及呈現互聯網內容的一種語言方式．被認為是互聯網的核心技術之一，HTML產生于1990年，1997年HTML4成為互聯網標準，并廣泛應用于互聯網應用的開發， HTML5是Web中核心語言HTML的規范，用戶使用任何手段進行網頁瀏覽時看到的內容原本都是HTML格式的，在瀏覽器中通過一些技術處理將其轉換成為了可識別的資訊，HTML5在從前HTML4.01的基礎上進行了一定的改進，雖然技術人員在開發程序中可能不會將這些新技術投入應用，但是對于該種技術的新特性，網站開發技術人員是必須要有所了解的， [1-2] </p> </details> </body> </html>
ruby和rt進行拼音的注釋
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> 我們來<ruby>夼<rt>kuang</rt></ruby>一個話題 </body> </html>
兼容瀏覽器的寫法：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> 我們來<ruby>夼<rp>(</rp><rt>Kuang</rt><rp>)</rp></ruby>一個話題 </body> </html>
mark黃色選中效果
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> <p>媽媽叫我回家的時候順路買一盒<mark>牛奶</mark>，需要很新鮮的那種，</p> </body> </html>
output表單計算
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> <form oninput="sum.value=https://www.cnblogs.com/dongmll/p/parseInt(num1.value)*parseInt(num2.value)"> <input type="number" id="num1">* <input type="number" id="num2">= <output name="sum" for="num1 num2"></output> </form> </body> </html>
date pickers在移動端效果比較好
week兼容性不好
datetime兼容性不好，推薦用datetime-local
time用來設定時間（小時和分鐘）；
month用來設定年和月；
date用來設定年月日；
datetime用來設定年月日和時間；
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> email:<input type="email" name="email"><br> url:<input type="url" name="url"><br> tel:<input type="tel" name="tel"><br> number:<input type="number" name="number"><br> date:<input type="date" name="date"><br> month:<input type="month" name="month"><br> week:<input type="week" name="week"><br> time:<input type="time" name="time"><br> datetime:<input type="datetime" name="datetime"><br> datetime-local:<input type="datetime-local" name="datetime-local"><br> range:<input type="range" name="range" min="1" max="10"><br> search:<input type="search" name="search"><br> color:<input type="color" name="color"><br> </body> </html>
autocomplete屬性規定form或input域擁有自動完成功能，該屬性適用于<form>標簽和<input>標簽
autofocus自動獲取焦點
multiple多選，適用于email和file，email中不同郵箱用,隔開
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> </head> <body> <form action="lesson2_1 autocomplete.html" autocomplete="on"> <input type="text" name="text" autofocus="autofocus" placeholder="您好，請在這里輸入您的用戶名！"><br> <input type="email" name="email" autocomplete="off" multiple="multiple"><br> <input type="file" name="file" multiple="multiple"><br> <input type="submit"> </form> </body> </html>
<link>標簽中，sizes屬性可以規定被鏈接資源的尺寸的大小
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> <link rel="icon" href="icon.gif" type="image/gif" sizes="16x16"> <base href="http://localhost" target="_blank"> </head> <body> </body> </html>
script:
defer 頁面已完成加載后再執行腳本
async 一旦腳本可用，則異步執行
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>demo</title> <script async="async" type="text/javascript" src="async.js"></script> <script defer="defer" type="text/javascript" src="defer.js"></script> </head> <body> </body> </html>
ol有序串列倒序
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Ol</title> </head> <body> <ol start="2" reversed="reversed"> <li>Html</li> <li>Html5</li> <li>Css</li> <li>Css3</li> <li>JavaScript</li> </ol> </body> </html>
