如何样式的html“选择”元素的选项?

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。

当前回答

这里有一些方法来样式<option>和<select>如果你使用Bootstrap和/或jquery。我知道这不是最初的海报要问的问题，但我想我可以帮助其他无意中遇到这个问题的人。

您仍然可以实现分别为每个<option>设置样式的目标，但可能还需要对<select>应用一些样式。我最喜欢的是下面提到的“Bootstrap Select”库。

Bootstrap选择库(jquery)

如果你已经在使用bootstrap，你可以尝试bootstrap Select库或下面的库(因为它有一个bootstrap主题)。

注意，您可以对整个选择元素或选项元素分别设置样式。

例子:

依赖:需要jQuery v1.9.1+， Bootstrap, Bootstrap的下拉菜单.js组件，和Bootstrap的CSS

兼容性:不确定，但bootstrap说它“支持所有主流浏览器和平台的最新稳定版本”

演示:https://developer.snapappointments.com/bootstrap-select/examples/

.special { font-weight: bold !important; color: #fff !important; background: #bc0000 !important; text-transform: uppercase; } <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <link href="https://stackpath.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" /> <link href="https://cdn.jsdelivr.net/npm/bootstrap-select@1.13.9/dist/css/bootstrap-select.min.css" rel="stylesheet" /> <script src="https://cdn.jsdelivr.net/npm/bootstrap-select@1.13.9/dist/js/bootstrap-select.min.js"></script> <select class="selectpicker"> <option>Mustard</option> <option class="special">Ketchup</option> <option style="background: #5cb85c; color: #fff;">Relish</option> </select>

Select2 (JS lib)

你可以使用一个叫做Select2的库。

依赖:库是JS + CSS + HTML(不需要JQuery)。

兼容性:IE 8+， Chrome 8+， Firefox 10+， Safari 3+， Opera 10.6+

演示:https://select2.org/getting-started/basic-usage

还有一个引导主题可用。

无引导的例子:

$(function() { var $select = $('.select2'); $select.select2({ theme: 'paper' }); }); <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.7/js/select2.min.js"></script> <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.7/css/select2.min.css" rel="stylesheet"/> <select class="select2 form-control" placeholder="Country"> <optgroup label="Alaskan/Hawaiian Time Zone"> <option value="AK">Alaska</option> <option value="HI">Hawaii</option> </optgroup> <optgroup label="Pacific Time Zone"> <option value="CA">California</option> <option value="NV">Nevada</option> <option value="OR">Oregon</option> <option value="WA">Washington</option> </optgroup> </select>

自举的例子:

$(function() { var $select = $('.select2'); $select.select2({ theme: 'paper' }); }); <link href="https://cdnjs.cloudflare.com/ajax/libs/bootswatch/3.3.2/paper/bootstrap.css" rel="stylesheet"/> <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.7/js/select2.min.js"></script> <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.7/css/select2.min.css" rel="stylesheet"/> <select class="select2 form-control" placeholder="Country"> <optgroup label="Alaskan/Hawaiian Time Zone"> <option value="AK">Alaska</option> <option value="HI">Hawaii</option> </optgroup> <optgroup label="Pacific Time Zone"> <option value="CA">California</option> <option value="NV">Nevada</option> <option value="OR">Oregon</option> <option value="WA">Washington</option> </optgroup> </select>

MDBootstrap ($ & Bootstrap & JQuery)

如果你有多余的钱，你可以使用高级库MDBootstrap。(这是一个完整的UI工具包，所以它不轻)

这允许您使用材质设计来设置选择和选项元素的样式。

有一个免费的版本，但它不允许你使用漂亮的材质设计!

依赖:Bootstrap 4, JQuery，

兼容性:“支持所有主流浏览器和平台的最新稳定版本。”

其他回答

似乎我可以直接在Chrome或Firefox中为选择设置CSS。CSS和HTML代码提供如下:

. boldoption { font-weight: bold; 的选择< > <option>一些规范-字体 <option>另一种规范-字体option</option> <option class=“boldoption”>一些勇敢的选择</option> 选择< - >

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

// Iterate over each select element $('select').each(function() { // Cache the number of options var $this = $(this), numberOfOptions = $(this).children('option').length; // Hides the select element $this.addClass('s-hidden'); // Wrap the select element in a div $this.wrap('<div class="select"></div>'); // Insert a styled div to sit over the top of the hidden select element $this.after('<div class="styledSelect"></div>'); // Cache the styled div var $styledSelect = $this.next('div.styledSelect'); // Show the first select option in the styled div $styledSelect.text($this.children('option').eq(0).text()); // Insert an unordered list after the styled div and also cache the list var $list = $('<ul />', { 'class': 'options' }).insertAfter($styledSelect); // Insert a list item into the unordered list for each select option for (var i = 0; i < numberOfOptions; i++) { $('<li />', { text: $this.children('option').eq(i).text(), rel: $this.children('option').eq(i).val() }).appendTo($list); } // Cache the list items var $listItems = $list.children('li'); // Show the unordered list when the styled div is clicked (also hides it if the div is clicked again) $styledSelect.click(function(e) { e.stopPropagation(); $('div.styledSelect.active').each(function() { $(this).removeClass('active').next('ul.options').hide(); }); $(this).toggleClass('active').next('ul.options').toggle(); }); // Hides the unordered list when a list item is clicked and updates the styled div to show the selected list item // Updates the select element to have the value of the equivalent option $listItems.click(function(e) { e.stopPropagation(); $styledSelect.text($(this).text()).removeClass('active'); $this.val($(this).attr('rel')); $list.hide(); /* alert($this.val()); Uncomment this for demonstration! */ }); // Hides the unordered list when clicking outside of it $(document).click(function() { $styledSelect.removeClass('active'); $list.hide(); }); }); body { padding: 50px; background-color: white; } .s-hidden { visibility: hidden; padding-right: 10px; } .select { cursor: pointer; display: inline-block; position: relative; font: normal 11px/22px Arial, Sans-Serif; color: black; border: 1px solid #ccc; } .styledSelect { position: absolute; top: 0; right: 0; bottom: 0; left: 0; background-color: white; padding: 0 10px; font-weight: bold; } .styledSelect:after { content: ""; width: 0; height: 0; border: 5px solid transparent; border-color: black transparent transparent transparent; position: absolute; top: 9px; right: 6px; } .styledSelect:active, .styledSelect.active { background-color: #eee; } .options { display: none; position: absolute; top: 100%; right: 0; left: 0; z-index: 999; margin: 0 0; padding: 0 0; list-style: none; border: 1px solid #ccc; background-color: white; -webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.2); -moz-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.2); box-shadow: 0 1px 2px rgba(0, 0, 0, 0.2); } .options li { padding: 0 6px; margin: 0 0; padding: 0 10px; } .options li:hover { background-color: #39f; color: white; } <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <select id="selectbox1"> <option value="">Select an option…</option> <option value="aye">Aye</option> <option value="eh">Eh</option> <option value="ooh">Ooh</option> <option value="whoop">Whoop</option> </select> <select id="selectbox2"> <option value="">Month…</option> <option value="january">January</option> <option value="february">February</option> <option value="march">March</option> <option value="april">April</option> <option value="may">May</option> <option value="june">June</option> <option value="july">July</option> <option value="august">August</option> <option value="september">September</option> <option value="october">October</option> <option value="november">November</option> <option value="december">December</option> </select>

这里留下一个快速的替代方法，使用表上的类切换。它的行为与选择非常相似，但是可以使用过渡、滤镜和颜色进行样式化，每个子元素都是独立的。

实际上你可以添加:before和:after并设置样式。至少它是有意义的

选择{ 字体大小:18 px; background - color: # ffffff; ｝之前选择:{ 内容:“>”; 字体大小:20 px; 显示:没有; padding-right: 10 px; padding-left: 5 px; 颜色:# fff; ｝选择:徘徊:{之前显示:内联; ｝ <select id="ddlProducts" name="ddProducts"> <option>Product1: Electronics </option> <option>Product2: Sports </option> < /选择>
