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。

我发现并使用了这个样式化选择和选项的好例子。你可以选择你想要的。小提琴在这里

正如已经提到的,唯一的方法是使用一个插件来替换<select>功能。

看一下使用Select2 plugin: http://jsfiddle.net/swsLokfj/23/的例子

如果你不想使用JavaScript,试试这个:

select {
  margin-top: 2% !important;
  font-size: 19px !important;
  text-align: center !important;
  width: 25% !important;
  padding: 6px 12px !important;
}
option {
  min-height: 1.5rem !important;
  padding: 14px !important;
}

可以应用于<option>元素的样式属性很少。

这是因为这种类型的元素是一个“替换元素”的例子。它们依赖于操作系统,不是HTML/浏览器的一部分。它不能通过CSS样式。

有一些替换的插件/库看起来像<select>,但实际上是由常规的HTML元素组成的,可以设置样式。

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。
