iOS选择圆角背景颜色

Question

我在Safari和Firefox上的iOS上都出现显示问题。我对输入栏（文本和选择）的圆角显示不正确。在Windows和Android设备上的Firefox下，它们可以正确显示。

具体来说，iOS下的选择字段的圆角外面的颜色与控件所在窗体的背景颜色不同。我可以通过将以下内容添加到CSS -webkit-appearance: none;使其消失，但是下拉箭头也消失。

我不确定要针对的目标是将多余的小角变成表单的背景颜色background-color: #E0E0E0;

任何帮助将不胜感激。我的CSS包含以下内容

select
{
    border-radius: 25px;
    border: 1px solid;
    padding: 5px;
}

使用-webkit-appearance: none;

Answer 1

这对我有用。

选择带有箭头img的选项：

.select-css {
	display: block;
	font-size: 16px;
	font-family: sans-serif;
	font-weight: 700;
	color: #444;
	line-height: 1.3;
	padding: .6em 1.4em .5em .8em;
	width: 100%;
	max-width: 100%;
	box-sizing: border-box;
	margin: 0;
	border: 1px solid #aaa;
	box-shadow: 0 1px 0 1px rgba(0,0,0,.04);
	border-radius: .5em;
	-moz-appearance: none;
	-webkit-appearance: none;
	appearance: none;
	background-color: #fff;
	background-image: url('data:image/svg+xml;charset=US-ASCII,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20width%3D%22292.4%22%20height%3D%22292.4%22%3E%3Cpath%20fill%3D%22%23007CB2%22%20d%3D%22M287%2069.4a17.6%2017.6%200%200%200-13-5.4H18.4c-5%200-9.3%201.8-12.9%205.4A17.6%2017.6%200%200%200%200%2082.2c0%205%201.8%209.3%205.4%2012.9l128%20127.9c3.6%203.6%207.8%205.4%2012.8%205.4s9.2-1.8%2012.8-5.4L287%2095c3.5-3.5%205.4-7.8%205.4-12.8%200-5-1.9-9.2-5.5-12.8z%22%2F%3E%3C%2Fsvg%3E'),
	  linear-gradient(to bottom, #ffffff 0%,#e5e5e5 100%);
	background-repeat: no-repeat, repeat;
	background-position: right .7em top 50%, 0 0;
	background-size: .65em auto, 100%;
}

<select class="select-css">
	<option>This is a native select element</option>
	<option>Apples</option>
	<option>Bananas</option>
	<option>Grapes</option>
	<option>Oranges</option>
</select>

重要的部分是这个

.select-css {
  -webkit-appearance: none;
  -webkit-border-radius: 0px;
}
