如何向html下拉列表中添加填充?

I want to add padding to the options of html "select" tag.

我想在html“选择”标签的选项中添加填充。

I try to add it in the style property of "select" and "option" and it doesn't work in IE.

我尝试将它添加到“select”和“option”的style属性中，但它在IE中不起作用。

What can I do?

OK, I hate to sound all 1990s, but would simply pre- and app-ending a space to the option text be acceptable for your desired goals?

好吧，我讨厌整个20世纪90年代都是这样，但是简单地在选项文本前加上一个空格是否可以满足您的目标呢?

It is difficult to style a drop down box cross browser. To get any sort of control, you'll need to code a replacement one in JavaScript. Be warned, however:

跨浏览器的下拉框很难设计样式。要获得任何类型的控制，您需要在JavaScript中编写一个替换的代码。然而,需要注意:

• Remember that the user may have difficulty using your drop down - take usabilty into account
• 记住，用户可能有困难使用您的下拉-考虑到usabilty
• Replace a select element with JS - this is an accessibility issue (and also allows users without JS support to use the form input)
• 用JS替换select元素——这是一个易访问性问题(也允许不支持JS的用户使用表单输入)

The following works, in FF3+ and Midori (and presumably other Webkit browsers):

FF3+和Midori(以及其他Webkit浏览器)的工作如下:

select
        {width: 14em;
        margin: 0 1em;
        text-indent: 1em;
        line-height: 2em;}

select *    {width: 14em;
        padding: 0 1em;
        text-indent: 0;
        line-height: 2em;}

The width is to allow enough room in the displayed select box when not active, the margin does what it always does, text-indent is used to feign padding between the left boundary of the select box and the inner-text. line-height is just to allow vertical spacing.

宽度是允许在显示的选择框中有足够的空间在不活动的时候，空白做它总是做的，文本缩进用于在选择框的左边界和内部文本之间假装填充。线高就是允许垂直间距。

I can't comment on its use in IE, I'm afraid, so if anyone could feed back -or adapt- to suit that'd be good.

我不能评论它在IE中的使用，所以如果有人能反馈或者适应的话，那就太好了。

It's worth noting that the drop-down part of the select (select *) isn't affected outside of FF3 for me, for whatever reason, so if that was the question you wanted answering, I apologise for offering nothing new.

值得注意的是，select (select *)的下拉部分在FF3之外对我没有影响，无论出于什么原因，所以如果这是您想要回答的问题，我为没有提供任何新的内容而道歉。

Create a class for the SELECT

为SELECT创建一个类。

.listBox{
   width: 200px; 
   ...etc
}

Now define the Css for the options of the SELECT

现在为SELECT选项定义Css

 .listBox option{
     padding:4px;
    ...etc
  }

Tested on IE 10

I couldnt get this to work with padding or spacing for some reason. I went with a jQuery solution that looks like this:

由于某种原因，我无法让它与填充或间距一起工作。我使用的jQuery解决方案是这样的:

$(document).click(function(){  
  $('#selector option').each(function(){  
    $(this).html("  "+$(this).text());  
  });  
});
