The CSS margin properties define the space around elements. It is possible to use negative values to overlap content. The top, right, bottom, and left margin can be changed independently using separate properties. A shorthand margin property can also be used to change all of the margins at once.
CSS邊距定義元素四周的空間范圍。它可讓內容重疊。也可用分離的屬性分別對上，下，左，右進行樣式改變。用margin屬性可以快速的設置所有邊距。

Note: Netscape and IE give the body tag a default margin of 8px. Opera does not! Instead, Opera applies a default padding of 8px, so if one wants to adjust the margin for an entire page and have it display correctly in Opera, the body padding must be set as well!
注重：網景和IE默認給body標簽加上了8px的邊距。OPERA就沒有這樣的情況，相反的，OPERA有個默認的8px填充，所以要讓頁面在幾個不同主流瀏覽器上的效果都相同就需要將屬性設置妥當！
