这是我的HTML:
<select id="ddlProducts" name="ddProducts">
<option>Product1 : Electronics </option>
<option>Product2 : Sports </option>
</select>
我想让产品的名称(即。'Product1', 'Product2',等等),以及它的类别(即。电子,体育等)斜体,只使用CSS。我发现了一个老问题,提到这是不可能使用HTML和CSS,但希望,现在有一个解决方案。
这是一个html css代码,用于样式选项和选择标签。
选择的选项:背景和粗体
关闭后,它看起来是斜体。
<style>
.mydropdown{
border:none;
border-bottom:2px dotted black;
display:inline;max-width:20%;
font-style: italic;
font-weight: 600;
cursor: pointer;
}
.mydropdown:hover , .myoption:active , .myoption:checked{
border:2px dotted green;
}
.myoption{
font-style: normal;
}
.mydropdown .myoption:checked,
.mydropdown .myoption:hover ,
.mydropdown .myoption:active {
font-style: italic;
font-weight: 600;
}
</style>
这就是你要找的东西吗?我用jQuery做的!
运行代码片段
