In this case, your frame is made of <!DOCTYPE>, <html>, <head>, and <body> tags. 就像房屋，一个html页面需要一个框架。在这里，你的框架是使用“<!DOCTYPE>”、“<html>”、“<head>”和“<body>”标签制作的。 Instructions 操作指南 Your webpage is blank as the day it was born! Let's add five things: 你的网页就像它出生时那样是空白的，让我们向内添加五件东西： 01. The <!DOCTYPE> tag 01. “<!DOCTYPE>”标签 02. Your <html> tags 02. “<html>”标签 03. Your <head> tags 03. “<head>”标签 04. <title> tags (with any title you like!) between your head tags 04. 在你的“<head>”标签间添加“<title>”标签（同时填入任何你想要的标题） 05. Your <body> tags 05. “<body>”标签
