为什么不能改变复选框颜色无论我做什么？

最佳答案

Checkboxes are not able to be styled. You would need a third party js plugin there are many available.

If you want to do this yourself it basically involves hiding the checkbox creating an element and styling that as you want then binding its click event to two functions one to change its look and another to activate the click event of the checkbox.

The same problem will arise when trying to style that little down arrow on a drop-down select element.

you cant change the background of checkbox but some how you can do a trick try this :)

.divBox {
width: 20px;
height: 20px;
background: #ddd;
margin: 20px 90px;
position: relative;
-webkit-box-shadow: 0px 1px 3px rgba(0,0,0,0.5);
-moz-box-shadow: 0px 1px 3px rgba(0,0,0,0.5);
box-shadow: 0px 1px 3px rgba(0,0,0,0.5);
}


.divBox label {
display: block;
width: 20px;
height: 20px;
-webkit-transition: all .5s ease;
-moz-transition: all .5s ease;
-o-transition: all .5s ease;
-ms-transition: all .5s ease;
transition: all .5s ease;
cursor: pointer;
position: absolute;
top: 1px;
z-index: 1;
/*
use this background transparent to check the value of checkbox
background: transparent;
*/
background: Black;
-webkit-box-shadow:inset 0px 1px 3px rgba(0,0,0,0.5);
-moz-box-shadow:inset 0px 1px 3px rgba(0,0,0,0.5);
box-shadow:inset 0px 1px 3px rgba(0,0,0,0.5);
}


.divBox input[type=checkbox]:checked + label {
background: green;
}

<div class="divBox">
<input type="checkbox" value="1" id="checkboxFourInput"name="" />
<label for="checkboxFourInput"></label>
</div>

Although the question is answered and is older, In exploring some options to overcome the the styling of check boxes issue I encountered this awesome set of CSS3 only styling of check boxes and radio buttons controlling background colors and other appearances. Thought this might be right up the alley of this question.

Technically, it is possible to change the color of anything with CSS. As mentioned, you can't change the background-color or color but you can use CSS filters. For example:

input[type="checkbox"] { /* change "blue" browser chrome to yellow */
filter: invert(100%) hue-rotate(18deg) brightness(1.7);
}

If you are really looking for design control over checkboxes though, your best bet is to do the "hidden" checkbox and style an adjacent element such as a div.

Transparency maybe: checkbox inside span

<span style="display:inline-block; background-color:silver;padding:0px;margin:0px;height:13px; width:13px; overflow:hidden"><input type="checkbox" style="opacity:0.50;padding:0px;margin:0px" /></span>

I had the same issue, trying to use large inputs and had a very small checkbox. After some searching, this is good enough for my needs:

input[type='checkbox']{
width: 30px !important;
height: 30px !important;
margin: 5px;
-webkit-appearance: none;
-moz-appearance: none;
-o-appearance: none;
appearance:none;
outline: 2px solid lightblue;
box-shadow: none;
font-size: 2em;
}

JSFiddle

Maybe someone will find it useful.

Agree with iLoveTux , applying too many things (many colors and backgrounds) nothing worked , but here's what started working, Apply these properties to its css:

-webkit-appearance: none;
-moz-appearance: none;
-o-appearance: none;
appearance:none;

and then css styling started working on checkbox :)

小开

Can be very simplified like that :

input[type="checkbox"]{
outline:2px solid red;
outline-offset: -2px;
}

Works without any plugin :)

小开

Let's say you have a checkbox with the class (bootstrap) .form-check-input. Then you can use an image for an example as the check mark.

SCSS code:

<input class="form-check-input" type="checkbox">

.form-check-input {
width: 22px;
height: 22px;
-webkit-appearance: none;
-moz-appearance: none;
-o-appearance: none;
appearance:none;
outline: 1px solid blue;


&:checked
{
background: white url('blue.svg') no-repeat;
background-size: 20px 20px;
background-position: 50% 50%;
}
}

Late but as a note: after upgrading Chrome to v/81, all check boxes & radio buttons turned blue. So here is a dead simple solution if you ain't okay with blue but with grayscale;

input[type='checkbox'], input[type='radio'] { filter: grayscale(1) }

See more on MDN:

Yes, you can. Based on knowledge from colleagues here and researching on web, here you have the best solution for styling a checkbox without any third-party plugin:

input[type='checkbox']{
width: 14px !important;
height: 14px !important;
margin: 5px;
-webkit-appearance: none;
-moz-appearance: none;
-o-appearance: none;
appearance: none;
outline: 1px solid gray;
box-shadow: none;
font-size: 0.8em;
text-align: center;
line-height: 1em;
background: red;
}


input[type='checkbox']:checked:after {
content: '✔';
color: white;
}

<input type='checkbox'>

One line of CSS is enough using hue-rotate filter. You can change their sizes with transform: scale() as well.

.checkbox { filter: hue-rotate(0deg) }

Codepen

.c1 { filter: hue-rotate(0deg)   }
.c2 { filter: hue-rotate(30deg)  }
.c3 { filter: hue-rotate(60deg)  }
.c4 { filter: hue-rotate(90deg)  }
.c5 { filter: hue-rotate(120deg) }
.c6 { filter: hue-rotate(150deg) }
.c7 { filter: hue-rotate(180deg) }
.c8 { filter: hue-rotate(210deg) }
.c9 { filter: hue-rotate(240deg) }


input[type=checkbox] {
transform: scale(2);
margin: 10px;
cursor: pointer;
}


/* Prevent cursor being `text` between checkboxes */
body { cursor: default }

<input type="checkbox" class="c1" />
<input type="checkbox" class="c2" />
<input type="checkbox" class="c3" />
<input type="checkbox" class="c4" />
<input type="checkbox" class="c5" />
<input type="checkbox" class="c6" />
<input type="checkbox" class="c7" />
<input type="checkbox" class="c8" />
<input type="checkbox" class="c9" />

Styling the arrow & the checkbox colors.

I haven't seen any answer deal with the arrow colors, so I thought I might add this for those wanting to also style the arrow inside the checkbox. I'm not suggesting to do these things, it's just for demo purposes.

.checkbox-label {
display: block;
position: relative;
margin: auto;
cursor: pointer;
font-size: 22px;
line-height: 24px;
height: 24px;
width: 24px;
clear: both;
}


.checkbox-label input {
position: absolute;
opacity: 0;
cursor: pointer;
}


.checkbox-label .checkbox-custom {
position: absolute;
top: 0px;
left: 0px;
height: 24px;
width: 24px;
background-color: transparent;
border-radius: 5px;
transition: all 0.3s ease-out;
-webkit-transition: all 0.3s ease-out;
-moz-transition: all 0.3s ease-out;
-ms-transition: all 0.3s ease-out;
-o-transition: all 0.3s ease-out;
border: 2px solid #000;
}




.checkbox-label input:checked ~ .checkbox-custom {
background-color: #FFEA00;
border-radius: 5px;
-webkit-transform: rotate(0deg) scale(1);
-ms-transform: rotate(0deg) scale(1);
transform: rotate(0deg) scale(1);
opacity:1;
border: 2px solid #000;
}


.checkbox-label .checkbox-custom::after {
position: absolute;
content: "";

I also had this problem. I use chrome to code because I'm currently a newbie. I was able to change the colour of the checkboxes and radio selectors when they were checked ONLY using CSS. The current degree that is set in the hue-rotate() turns the blue checks red. I first used the grayscale(1) with the filter: but you don't need it. However, if you just want plain flat gray, go for the grayscale value for filter.

I've ONLY tested this in Chrome but it works with just plain old HTML and CSS, let me know in the comments section if it works in other browsers.

input[type="checkbox"],
input[type="radio"] {
filter: hue-rotate(140deg);
}

<body>
<label for="radio1">Eau de Toilette</label>
<input type="radio" id="radio1" name="example1"><br>
<label for="radio2">Eau de Parfum</label>
<input type="radio" id="radio2" name="example1"><br>
<label for="check1">Orange Zest</label>
<input type="checkbox" id="check1" name="example2"><br>
<label for="check2">Lemons</label>
<input type="checkbox" id="check2" name="example2"><br>
</body>

This should solve it, also the checkmark set in content will center perfectly.

for an html element like: <input type="checkbox" />

input[type='checkbox']:checked {
background-color: rgb(60,69,77,0.9);
}
input[type='checkbox']:checked:after {
content: '\2713';
color:white;
}
input[type='checkbox']{
text-align: center;
display: table-cell;
vertical-align: middle;
width: 20px !important;
height: 20px !important;
appearance:none;
border-radius:10%;
border: 1px solid rgb(60,69,77,0.9);
box-shadow: none;
font-size: 1em;
}

You can now simply use the accent-color property :

#cb1 {
accent-color: #9b59b6;
}


#cb2 {
accent-color: #34495e;
}


#cb3 {
accent-color: #e74c3c;
}

<input id="cb1" type="checkbox" checked />
<input id="cb2" type="checkbox" checked />
<input id="cb3" type="checkbox" checked />

Note : as this is a new feature, it is not supported by all browsers, but it is still useful
