以前用到html字符的時候老是忘了該怎麼寫，我想和我一樣的人應該很多，現整理一下html字符，共享。
HTML特殊字符顯示 有些字符在HTML裏有特別的含義，比如小於號<就表示HTML Tag的開始，這個小於號是不顯示在我們最終看到的網頁裏的。那如果我們希望在網頁中顯示一個小於號，該怎麼辦呢？
這就要說到HTML字符實體(HTML Character Entities)了。
一個字符實體(Character Entity)分成三部分：第一部分是一個&符號，英文叫ampersand；第二部分是實體(Entity)名字或者是#加上實體(Entity)編號；第三部分是一個分號。
比如，要顯示小於號，就可以寫<或者<。
用實體(Entity)名字的好處是比較好理解，一看lt，大概就猜出是less than的意思，但是其劣勢在於並不是所有的瀏覽器都支持最新的Entity名字。而實體(Entity)編號，各種瀏覽器都能處理。
注意：Entity是區分大小寫的。
如何顯示空格
通 常情況下，HTML會自動截去多餘的空格。不管你加多少空格，都被看做一個空格。比如你在兩個字之間加了10個空格，HTML會截去9個空格，只保留一個。爲了在網頁中增加空格，你可以使用 表示空格。
