CSS設計徹底研究5.2節筆記

1.背景映像

(1)設定背景映像:background-image : none | url ( url )

(2)映像平鋪方向:background-repeat : repeat | no-repeat | repeat-x | repeat-y

(3)映像對齊:background-position : (center | top | bottom | length) | (center | left | right | length)(可以設定為一個或兩個屬性值,分別用於水平位置和豎直位置。)

【應用】製作漸層色背景

1)準備一張垂直漸層的背景映像;

2)將背景顏色設定為背景映像最下面一排像素的顏色。

代碼如下:

body{

background-image:url(bg_grad.gif);

background-repeat:repeat-x;

background-color:#39F;

}

或簡寫為:

body{

background:#39F url(bg_grad.gif) repeat-x;

}
