HTML 字符實體


HTML 中的預留字符必須被替換爲字符實體。api




HTML 實體


在 HTML 中,某些字符是預留的。瀏覽器


在 HTML 中不能使用小於號(<)和大於號(>),這是由於瀏覽器會誤認爲它們是標籤。less


若是但願正確地顯示預留字符,咱們必須在 HTML 源代碼中使用字符實體(character entities)。ide


字符實體相似這樣:post


&entity_name;
或者
&#entity_number;

如需顯示小於號,咱們必須這樣寫:&lt; 或 &#60;flex





不間斷空格(non-breaking space)


HTML 中的經常使用字符實體是不間斷空格(&nbsp;)。spa


瀏覽器老是會截短 HTML 頁面中的空格。若是您在文本中寫 10 個空格,在顯示該頁面以前,瀏覽器會刪除它們中的 9 個。如需在頁面中增長空格的數量,您須要使用 &nbsp; 字符實體。blog




HTML 實例示例


用 HTML 實體符號作實驗: here 親自試一試 HTML 實體符號參考手冊 ip

HTML ISO-8859-1 參考手冊


HTML 4.01 支持 ISO 8859-1 (Latin-1) 字符集。ci


ISO-8859-1 的較低部分(從 1 到 127 之間的代碼)是最初的 7 比特 ASCII。


ISO-8859-1 的較高部分(從 160 到 255 之間的代碼)全都有實體名稱。


這些符號中的大多數均可以在不進行實體引用的狀況下使用,可是實體名稱或實體編號爲那些不容易經過鍵盤鍵入的符號提供了表達的方法。


註釋:實體名稱對大小寫敏感。
