如何设置 HTML 选择/选项标签的样式? [英] How to style HTML select/option tag?

问题描述

我想创建一个带有 html select 的下拉菜单，因此我也想对其进行样式设置.我想为选项标签设置一个填充，这样它们就不会那么拥挤，但我不能这样做.(它不起作用)有什么想法吗?

#categories{填充:10px 10px 10px 10px；背景色:#826B78；字体大小:20px；白颜色;边距:10px 10px 10px 10px；边界:无；大纲:无；}#categories 选项{边距:30px 30px 30px 30px；填充:30px 30px 30px 30px；字体大小:20px；}

categories id 属于 select 标签

解决方案

使用 css 很难设置选择菜单的样式.最好的方法是使用 jquery，您可以使用 jquery 设置样式并更好地控制代码.只需使用像 http://gregfranko.com/jquery.selectBoxIt.js/

我刚刚用jquery做了一个样式选择的例子，你可以在这里查看演示

//将 select 转换为 UL 的代码$('.select').each(function() {var $select = $(this).find('select'),$list = $('
');$select.find('option').each(function() {$list.append('
' + $(this).text() + '
');});//取值后移除select$select.after($list).remove();//附加默认文本以显示选定的$(this).append('<span>select</span>')var firsttxt = $(this).find('li:first-child').text();$(this).find('span').text(firsttxt)//单击时显示 UL$(this).on('click', 'span', function(e) {e.stopPropagation();$(this).parent().find('ul').show();});//在选择列表时选择项目$(this).on('click', 'li', function() {var gettext = $(this).text();$(this).parents('.select').find('span').text(gettext);$(this).parent().fadeOut();});})//点击后隐藏 UL$(document).on('click', function() {$('.select ul').fadeOut();});

body {font-family: 'arial', san-serif;}.选择 {宽度:200px；高度:30px；边框:1px 实心#ddd；行高:30px；位置:相对；底边距:40px；}.选择跨度{显示:块；颜色:#333；字体大小:12px；填充:0 10px；}.select ul {显示:无；背景:#fff;边框:1px 实心#ddd；最小宽度:300px；位置:绝对；顶部:100%；左:0；列表样式类型:无；边距:0；填充:0；z-索引:10；}.select ul >李{字体大小:12px；}.select ul >李{颜色:#333；显示:块；填充:2px 8px；文字装饰:无；行高:24px；}.select ul >李:悬停{背景:#e4f4fa；光标:指针；}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><label>首选</label><div class="选择"><选择><option>项目</option><option>项目 2</option><option>项目 3</option></选择>

<label>第二个选择</label><div class="选择"><选择><option>这个1</option><option>这个 2</option><option>这个3</option></选择>

I would like to create a dropdown menu with html select thus I would like to style it as well. I would like to set a padding to the option tags so they wouldn't be so overcrowded, but I can't do so. (it doesn't work) any idea?

#categories
{
padding: 10px 10px 10px 10px;
background-color: #826B78;
font-size: 20px;
color: white;
margin: 10px 10px 10px 10px;
border: none;
outline: none;
}

#categories option
{
margin: 30px 30px 30px 30px;
padding: 30px 30px 30px 30px;
font-size: 20px;
}

the categories id belongs to the select tag

解决方案

It is difficult to style select menu with css. The Best way of doing it is with jquery u can style and have a better control over the code with jquery. Just use a custom jquery like http://gregfranko.com/jquery.selectBoxIt.js/

I have just made an example of styling select with jquery, you can check the demo here

// Code to convert select to UL
$('.select').each(function() {
  var $select = $(this).find('select'),
    $list = $('<ul />');
  $select.find('option').each(function() {
    $list.append('<li>' + $(this).text() + '</li>');
  });
  //Remove the select after the values are taken
  $select.after($list).remove();


  //Append Default text to show the selected
  $(this).append('<span>select</span>')
  var firsttxt = $(this).find('li:first-child').text();
  $(this).find('span').text(firsttxt)

  // On click show the UL
  $(this).on('click', 'span', function(e) {
    e.stopPropagation();
    $(this).parent().find('ul').show();
  });

  // On select of list select the item
  $(this).on('click', 'li', function() {
    var gettext = $(this).text();
    $(this).parents('.select').find('span').text(gettext);
    $(this).parent().fadeOut();
  });

})


// On click out hide the UL
$(document).on('click', function() {
  $('.select ul').fadeOut();
});

body {
  font-family: 'arial', san-serif;
}

.select {
  width: 200px;
  height: 30px;
  border: 1px solid #ddd;
  line-height: 30px;
  position: relative;
  margin-bottom: 40px;
}

.select span {
  display: block;
  color: #333;
  font-size: 12px;
  padding: 0 10px;
}

.select ul {
  display: none;
  background: #fff;
  border: 1px solid #ddd;
  min-width: 300px;
  position: absolute;
  top: 100%;
  left: 0;
  list-style-type: none;
  margin: 0;
  padding: 0;
  z-index: 10;
}

.select ul > li {
  font-size: 12px;
}

.select ul > li {
  color: #333;
  display: block;
  padding: 2px 8px;
  text-decoration: none;
  line-height: 24px;
}

.select ul > li:hover {
  background: #e4f4fa;
  cursor: pointer;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label>First Select</label>
<div class="select">  
    <select>
         <option>Item</option>
         <option>Item 2</option>
         <option>Item 3</option>
    </select>
</div>

<label>Second Select</label>
<div class="select">
    <select>
         <option>this 1</option>
         <option>this 2</option>
         <option>this 3</option>
    </select>
</div>
