注意事項：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
<html xmlns="http://www.w3.org/1999/xhtml ">
（1）標頭檔案必須這個,否則會報以下錯誤：
錯誤：“The declaration for the entity "HTML.Version" must end with '>'.”
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
（2）charset 必須是UTF-8,否則會報以下錯誤：
錯誤：“Invalid byte 1 of 1-byte UTF-8 sequence.”
（3）需要定一個樣式:body {font-family: SimSun};
（4）html頁面必須嚴格遵循, 該打引號就要打引號
錯誤：cellpadding=0 ,border=1"
(5)不要引用無效的連結
