|
| <img src="http://www.w3schools.com/images/smile.gif" /> |

現在我們插入<base>標籤，就可以爲頁面內的所有連接加上基礎URL：
| <head> <base href="http://www.w3schools.com/images/" /> </head> |
When inserting images on the page in the example above, we just have to specify the relative address, and the browser will look for that file using the full URL, "http://www.w3schools.com/images/smile.gif":
加上之後我們只需要指定相對的地址就可以將URL變爲"http://www.w3schools.com/images/smile.gif":
| <img src="smile.gif" /> |
