我的意思是,单选按钮本身由一个圆形和中心的一个点组成(当按钮被选中时)。我想改变的是两者的颜色。使用CSS可以做到这一点吗?
当前回答
正如Fred提到的,没有办法在颜色、大小等方面对单选按钮进行本地样式设置。但是您可以使用CSS Pseudo元素来设置任意给定单选按钮的冒名顶替者,并对其进行样式化。谈到JamieD所说的,关于我们如何使用:after Pseudo元素,您可以同时使用:before和:after来实现理想的外观。
这种方法的好处:
Style your radio button and also Include a label for content. Change the outer rim color and/or checked circle to any color you like. Give it a transparent look with modifications to background color property and/or optional use of the opacity property. Scale the size of your radio button. Add various drop shadow properties such as CSS drop shadow inset where needed. Blend this simple CSS/HTML trick into various Grid systems, such as Bootstrap 3.3.6, so it matches the rest of your Bootstrap components visually.
简短演示说明如下:
Set up a relative in-line block for each radio button Hide the native radio button sense there is no way to style it directly. Style and align the label Rebuilding CSS content on the :before Pseudo-element to do 2 things - style the outer rim of the radio button and set element to appear first (left of label content). You can learn basic steps on Pseudo-elements here - http://www.w3schools.com/css/css_pseudo_elements.asp If the radio button is checked, request for label to display CSS content (the styled dot in the radio button) afterwards.
HTML
<div class="radio-item">
<input type="radio" id="ritema" name="ritem" value="ropt1">
<label for="ritema">Option 1</label>
</div>
<div class="radio-item">
<input type="radio" id="ritemb" name="ritem" value="ropt2">
<label for="ritemb">Option 2</label>
</div>
CSS
.radio-item {
display: inline-block;
position: relative;
padding: 0 6px;
margin: 10px 0 0;
}
.radio-item input[type='radio'] {
display: none;
}
.radio-item label {
color: #666;
font-weight: normal;
}
.radio-item label:before {
content: " ";
display: inline-block;
position: relative;
top: 5px;
margin: 0 5px 0 0;
width: 20px;
height: 20px;
border-radius: 11px;
border: 2px solid #004c97;
background-color: transparent;
}
.radio-item input[type=radio]:checked + label:after {
border-radius: 11px;
width: 12px;
height: 12px;
position: absolute;
top: 9px;
left: 10px;
content: " ";
display: block;
background: #004c97;
}

总之,不需要JavaScript,图像或电池。纯CSS。

对于那些喜欢从最小示例开始开发的人来说,这里有一个简单的自定义单选按钮,它不依赖于标签:
[type="radio"] { visibility: hidden; /* hide default radio button */ /* you may need to adjust margin here, too */ } [type="radio"]::before { /* create pseudoelement */ border: 2px solid gray; /* thickness, style, color */ height: .9em; /* height adjusts with font */ width: .9em; /* width adjusts with font */ border-radius: 50%; /* make it round */ display: block; /* or flex or inline-block */ content: " "; /* won't display without this */ cursor: pointer; /* appears clickable to mouse users */ visibility: visible; /* reverse the 'hidden' above */ } [type="radio"]:checked::before { /* selected */ /* add middle dot when selected */ /* slightly bigger second value makes it smooth */ /* even more (e.g., 20% 50%) would make it fuzzy */ background: radial-gradient(gray 36%, transparent 38%); } <br> <input type="radio" name="example" id="one" value="one"> <label for="one">one</label> <br> <br> <input type="radio" name="example" id="two" value="two"> <label for="two">two</label>
单选按钮是特定于每个操作系统/浏览器的原生元素。没有办法改变它的颜色/风格,除非你想实现自定义图像或使用自定义Javascript库,其中包括图像(例如这个-缓存链接)
这在本地CSS中是不可能的。您必须使用背景图像和一些javascript技巧。
如果你使用react bootstrap Form。你可以这样做
HTML
<Form.Check
type="radio"
id="Radio-card"
label={`check me out`}
name="paymentmethod"
value="card"
/>
SCSS
.form-check {
display: flex;
align-items: center;
input[type="radio"] {
-moz-appearance: none;
appearance: none;
width: 11px;
height: 11px;
padding: 1px;
background-clip: content-box;
border: 1px solid hotpink;
background-color: white;
border-radius: 50%;
}
input[type="radio"]:checked {
outline: none;
background-color: hotpink;
border: 1px solid hotpink;
}
label {
font-size: 14px;
font-weight: 600;
}
}
简单的方法是使用重音色
CSS属性的作用是:为某些元素生成的用户界面控件设置强调色
支持重音颜色的浏览器目前将其应用于以下HTML元素:
<input type="checkbox">
<input type="radio">
<input type="range">
<progress>
一个可运行的示例
body { display: grid; padding: 3rem 0; } .accent { accent-color: #30cc7e; } form { display: grid; grid-auto-columns: fit-content(50%); grid-template-areas: "a a"; margin: auto; padding: 0; gap: 1rem; } form { display: grid; grid-template-columns: 1fr 1fr; gap: 2rem; margin: auto; } form section:first-child { color-scheme: light; } form section:last-child { color-scheme: dark; } fieldset { border-radius: 8px; color-scheme: light; display: flex; flex: 1; flex-direction: column; gap: 1rem; padding: 1rem; } .dark { color-scheme: dark; } .dark fieldset { background: #100f33; border-color: #100f33; color: #fff; } .dark .accent { accent-color: hsla(180, 100%, 70%, 1); } h2 { margin: 0; } .notice { background: #fff9c4; border-radius: 6px; margin: 1.5rem auto; padding: 0.5rem; text-align: center; } @supports (accent-color: #fff) { .notice { display: none; } } <div class="notice"> Your browser does not support the <code>accent-color</code> property. </div> <form action=""> <fieldset> <h2>Checkboxes</h2> <div> <label for="checkbox"> Default </label> <input id="checkbox" type="checkbox" checked> </div> <div> <label for="checkbox-accent"> Accent </label> <input id="checkbox-accent" type="checkbox" class="accent" checked> </div> </fieldset> <fieldset> <h2>Radio</h2> <div> <input id="radio" type="radio" checked> <label for="radio"> Default </label> </div> <div> <input id="radio-accent" type="radio" class="accent" checked> <label for="radio-accent"> Accent </label> </div> </fieldset> <fieldset> <h2>Progress</h2> <div> <label for="progress"> Default </label> <progress id="progress" min="0" max="100" value="50"></progress> </div> <div> <label for="progress-accent"> Accent </label> <progress id="progress-accent" class="accent" min="0" max="100" value="50"></progress> </div> </fieldset> <fieldset> <h2>Range</h2> <div> <label for="range"> Default </label> <input id="range" type="range"> </div> <div> <label for="range-accent"> Accent </label> <input id="range-accent" class="accent" type="range"> </div> </fieldset> </form>
