下面小編就為大家帶來一篇淺談HTML5 新增及移除的元素。小編覺得蠻不錯的，現在就分享給大家，也給大家做個參考。一起跟著小編過來看看吧

HTML經過10多年的發展，其元素經歷了廢棄與不斷重新定義的過程。為了更好的處理現在的網路應用，HTML5新增了圖形繪製、多媒體播放、頁面結構、應用程式儲存、網路工作等新元素。

圖形繪製新元素

##<canvas>

#標籤	描述

#標籤定義圖形，例如圖表和其他圖像。這個標籤基於JavaScript 的繪圖

API#新多媒體元素描述定義音訊內容#定義內容定義多媒體資源（audio或vedio）


	標籤
	#

影片

#定義嵌入的內容，例如外掛程式

為如video和audio元素之類的媒介規定外部文字軌道新表單元素#標籤說明##list

>#######定義選項清單。請與 input 元素搭配使用該元素，來定義 input 可能的值。 ############<###key###gen>#######規定用於表單的金鑰對###產生器###欄位。 ##################定義不同類型的輸出，例如腳本的輸出。 ############

新的語意和結構元素

HTML5提供了新的元素來建立更適用的頁面。
