如何仅使用CSS设置<select>下拉列表的样式？

神奇Davaid2020-03-13

是否有仅CSS样式的<select>下拉菜单？

我需要在<select>不使用任何JavaScript的情况下尽可能地样式化表单。我可以在CSS中使用哪些属性？

此代码需要与所有主要浏览器兼容：

  • Internet Explorer 6、7和8
  • 火狐浏览器
  • 苹果浏览器

我知道我可以使用JavaScript实现：Example。

我不是在谈论简单的样式。我想知道，仅CSS可以做得最好。

我在堆栈溢出中发现了类似的问题。

而这个在Doctype.com上。

You can also add a hover style to the dropdown.

select {position:relative; float:left; width:21.4%; height:34px; background:#f9f9e0; border:1px solid #41533f; padding:0px 10px 0px 10px; color:#41533f; margin:-10px 0px 0px 20px; background: transparent; font-size: 12px; -webkit-appearance: none; -moz-appearance: none; appearance: none; background: url(https://alt-fit.com/images/global/select-button.png) 100% / 15% no-repeat #f9f9e0;}
select:hover {background: url(https://alt-fit.com/images/global/select-button.png) 100% / 15% no-repeat #fff;}
<html>
<head>
</head>
<body>
<select name="type" class="select"><option style="color:#41533f;" value="Select option">Select option</option>
<option value="Option 1">Option 1</option>
<option value="Option 2">Option 2</option>
<option value="Option 3">Option 3</option>
</select>
</body>
</html>

You definitely should do it like in Styling select, optgroup and options with CSS. In many ways, background-color and color are just what you would typically need to style options, not the entire select.

Sam神奇A2020/03/13 17:36:00

Yes. You may style any HTML element by its tag name, like this:

select {
  font-weight: bold;
}

Of course, you can also use a CSS class to style it, like any other element:

<select class="important">
  <option>Important Option</option>
  <option>Another Important Option</option>
</select>

<style type="text/css">
  .important {
    font-weight: bold;
  }
</style>

A very nice example that uses :after and :before to do the trick is in Styling Select Box with CSS3 | CSSDeck

TonyDavaid2020/03/13 17:35:59
label {
    position: relative;
    display: inline-block;
}
select {
    display: inline-block;
    padding: 4px 3px 5px 5px;
    width: 150px;
    outline: none;
    color: black;
    border: 1px solid #C8BFC4;
    border-radius: 4px;
    box-shadow: inset 1px 1px 2px #ddd8dc;
    background-color: lightblue;
}

This uses a background color for select elements and I removed the image..

Tom神奇2020/03/13 17:35:59
select  {
    outline: 0;
    overflow: hidden;
    height: 30px;
    background: #2c343c;
    color: #747a80;
    border: #2c343c;
    padding: 5px 3px 5px 10px;
    -moz-border-radius: 6px;
    -webkit-border-radius: 6px;
    border-radius: 10px;
}

select option {border: 1px solid #000; background: #010;}

使用该clip属性裁剪select元素的边框和箭头，然后将自己的替换样式添加到包装器中：

    <!DOCTYPE html>
    <html>
      <head>
        <style>
          select { position: absolute; clip:rect(2px 49px 19px 2px); z-index:2; }
          body > span { display:block; position: relative; width: 64px; height: 21px; border: 2px solid green;  background: url(http://www.stackoverflow.com/favicon.ico) right 1px no-repeat; }
        </style>
      </head>
      <span>
        <select>
          <option value="">Alpha</option>
          <option value="">Beta</option>
          <option value="">Charlie</option>
        </select>
      </span>
    </html>

使用不透明度为零的第二个选择使按钮可单击：

    <!DOCTYPE html>
    <html>
      <head>
        <style>
          #real { position: absolute; clip:rect(2px 51px 19px 2px); z-index:2; }
          #fake { position: absolute; opacity: 0; }
    
          body > span { display:block; position: relative; width: 64px; height: 21px; background: url(http://www.stackoverflow.com/favicon.ico) right 1px no-repeat; }
        </style>
      </head>
      <span>
        <select id="real">
          <option value="">Alpha</option>
          <option value="">Beta</option>
          <option value="">Charlie</option>
        </select>
        <select id="fake">
          <option value="">Alpha</option>
          <option value="">Beta</option>
          <option value="">Charlie</option>
        </select>
      </span>
    </html>

Webkit和其他浏览器之间的坐标不同，但是@media查询可以解决此问题。

这是适用于所有现代浏览器的版本。使用该键可appearance:none删除默认格式。由于所有格式都不用了，因此您必须重新添加箭头，以可视方式将选择内容与输入内容区分开。

这是可能的，但不幸的是，大多数情况下，在开发人员需要的程度上基于WebKit的浏览器中。这是通过内置开发人员工具检查器从Chrome选项面板收集的CSS样式示例，经过改进以匹配大多数现代浏览器中当前支持的CSS属性：

select {
    -webkit-appearance: button;
    -moz-appearance: button;
    -webkit-user-select: none;
    -moz-user-select: none;
    -webkit-padding-end: 20px;
    -moz-padding-end: 20px;
    -webkit-padding-start: 2px;
    -moz-padding-start: 2px;
    background-color: #F07575; /* Fallback color if gradients are not supported */
    background-image: url(../images/select-arrow.png), -webkit-linear-gradient(top, #E5E5E5, #F4F4F4); /* For Chrome and Safari */
    background-image: url(../images/select-arrow.png), -moz-linear-gradient(top, #E5E5E5, #F4F4F4); /* For old Firefox (3.6 to 15) */
    background-image: url(../images/select-arrow.png), -ms-linear-gradient(top, #E5E5E5, #F4F4F4); /* For pre-releases of Internet Explorer  10*/
    background-image: url(../images/select-arrow.png), -o-linear-gradient(top, #E5E5E5, #F4F4F4); /* For old Opera (11.1 to 12.0) */
    background-image: url(../images/select-arrow.png), linear-gradient(to bottom, #E5E5E5, #F4F4F4); /* Standard syntax; must be last */
    background-position: center right;
    background-repeat: no-repeat;
    border: 1px solid #AAA;
    border-radius: 2px;
    box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.1);
    color: #555;
    font-size: inherit;
    margin: 0;
    overflow: hidden;
    padding-top: 2px;
    padding-bottom: 2px;
    text-overflow: ellipsis;
    white-space: nowrap;
}

在基于WebKit的浏览器中的任何页面上运行此代码时，它都应更改选择框的外观，删除标准的OS箭头，并添加PNG箭头，在标签前后放置一些空格，几乎是您想要的任何内容。

最重要的部分是appearance属性，它可以更改元素的行为。

它appearance似乎可以在几乎所有基于WebKit的浏览器中完美运行，包括移动浏览器，尽管Gecko并不像WebKit 那样受支持。

理查德小宇宙2020/03/13 17:35:59

在样式化选择下拉列表时，我注意到的最大不一致是Safari和Google Chrome渲染（Firefox可以通过CSS完全自定义）。经过对Internet晦涩深度的搜索后，我发现以下内容几乎可以完全解决WebKit的问题：

Safari和Google Chrome浏览器修复：

select {
  -webkit-appearance: none;
}

但是，这确实删除了下拉箭头。您可以使用附近div带有背景，负边距或绝对位于所选下拉菜单上方的箭头来添加下拉箭头。

*更多信息和其他变量可在CSS属性中找到：-webkit-appearance。

猿小小2020/03/13 17:35:59

选择元素及其下拉功能是很难的风格。

克里斯·海尔曼（Chris Heilmann）的 select元素的样式属性证实了Ryan Dohery在对第一个答案的评论中所说的话：

“ select元素是操作系统的一部分，而不是浏览器chrome。因此，它的样式非常不可靠，无论如何尝试都不一定有意义。”

Harry前端Itachi2020/03/13 17:35:59

我遇到了这个确切的问题，除了我无法使用图像并且不受浏览器支持的限制。这应该是“规范的”，运气好的话，最终可以在任何地方开始工作。

它使用分层的旋转背景层来“切出”下拉箭头，因为伪元素对select元素不起作用。

编辑：在此更新的版本中，我正在使用CSS变量和一个很小的主题系统。

<select>标签可以通过CSS设置样式，就像在浏览器中呈现的HTML页面上的任何其他HTML元素一样。下面是一个（过于简单的）示例，它将在页面上放置一个select元素，并以蓝色显示选项的文本。

HTML示例文件（selectExample.html）：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
  <title>Select Styling</title>
  <link href="selectExample.css" rel="stylesheet">
</head>
<body>
<select id="styledSelect" class="blueText">
  <option value="apple">Apple</option>
  <option value="orange">Orange</option>
  <option value="cherry">Cherry</option>
</select>
</body>
</html>
