[英]How do I keep a <div> that's underneath a partially transparent .png, scrollable?
[英]How do I set a partially transparent background on a div?
我希望div部分透明,以便可以透視背景,但希望其他元素<p>
不像圖像中那樣透明。 目前,我正在使用opacity: .4
。

和屏幕截圖:
使用rgba顏色而不是影響元素子元素的opacity
。
例如
background-color: #AEABA1
opacity: .4
將轉化為:
background-color: rgba(174, 171, 161, 0.4)
您可以在此處找到HEX到RGBA轉換器
對於類.tarifas_left_top
和.tarifas_left_bottom
,刪除opacity
,而使用background-color: rgba(#,#,#,#)
。 對於不透明度為0.4的背景顏色#AEABA1
,它轉換為background-color: rgba(174,171,161,0.4)
。
對於IE 8及更低版本,您需要使用filter
屬性覆蓋背景。
.tarifas_left_top {
background-color: rgba(174,171,161,0.4);
background: transparent\9;
/* This '\9' is intentional. It's a CSS hack, but
it works, and it resets the background in IE 8
and below only. */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#66AEABA1,endColorstr=#66AEABA1);
zoom: 1;
}
有效地,這為您提供了跨瀏覽器的半透明背景,而不影響元素子級的不透明度。 這些屬性也可以用於border-color
和color
屬性。
