只需尝试以下内容:
CSS部分:
解决方案#1:
input[type="text"], textarea, select, option {
border:none;
padding:5px;
font-size:14px;
color: rgb(0, 0, 0);
background: rgba(0, 0, 0, 0.1);
/* Theoretically for IE 8 & 9 (more valid) */
/* ...but not required as filter works too */
/* should come BEFORE filter */
-ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
/* This works in IE 8 & 9 too */
/* ... but also 5, 6, 7 */
filter: alpha(opacity=50);
/* Older than Firefox 0.9 */
-moz-opacity:0.5;
/* Safari 1.x (pre WebKit!) */
-khtml-opacity: 0.5;
/* Modern!
/* Firefox 0.9+, Safari 2?, Chrome any?
/* Opera 9+, IE 9+ */
opacity: 0.5;
}
解决方案#2:
input[type="text"], textarea, select, option {
border:none;
padding:5px;
font-size:14px;
color: #000000;
background: rgba(0, 0, 0, 0.1);
}
select
{
-webkit-appearance: none;
}
This second solution will work perfectly, except the dropdown arrow, we need to set the dropdown arrow image via background url css. because chrome where defaultly applying the **User Agent Stylesheet** for Select Dropdown Elements.
请参考以下地点:
(1)。什么是用户代理样式表?
(2)。CSS2.1 用户代理样式表默认值?
(3)。用户代理样式表:基础和示例?
HTML部分:
<select>
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
</select>
我认为这可以帮助您解决问题。
