Html 为什么无论我做什么都无法更改复选框颜色？

Why cannot change checkbox color whatever I do?

提问by Ari

I try to style checkbox background color, but it won't change whatever I do. I am using firefox 29 latest.

我尝试设置复选框背景颜色的样式，但无论我做什么它都不会改变。我正在使用最新的 Firefox 29。

Is there some rule changes in css or may be in the browser?

css 中是否有一些规则更改或可能在浏览器中？

CSS:

CSS：

input[type="checkbox"] {
    background: #990000;    
}

.chk {
   background-color: #990000;  

}

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

复选框无法设置样式。你需要一个第三方 js 插件，有很多可用的插件。

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.

如果您想自己执行此操作，它基本上涉及隐藏复选框，根据需要创建元素和样式，然后将其单击事件绑定到两个函数，一个用于更改其外观，另一个用于激活复选框的单击事件。

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

尝试为下拉选择元素上的小向下箭头设置样式时，会出现同样的问题。

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.

尽管问题已得到解答并且较旧，但在探索克服复选框样式问题的一些选项时，我遇到了一组非常棒的 CSS3 样式，仅用于控制背景颜色和其他外观的复选框和单选按钮的样式。认为这可能是这个问题的小巷。

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:

我遇到了同样的问题，尝试使用大输入并且有一个非常小的复选框。经过一番搜索，这足以满足我的需求：

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;
}

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:

从技术上讲，可以使用 CSS 更改任何内容的颜色。如前所述，您不能更改背景颜色或颜色，但可以使用 CSS 过滤器。例如：

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.

但是，如果您真的希望对复选框进行设计控制，那么最好的办法是执行“隐藏”复选框并设置相邻元素（例如 div）的样式。

回答by gael

Can be very simplified like that :

可以非常简化：

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

Works without any plugin :)

无需任何插件即可工作:)

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.

假设您有一个带有类 (bootstrap) .form-check-input 的复选框。然后您可以使用图像作为示例作为复选标记。

SCSS code:

SCSS代码：

<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 I upgraded Chrome to v/81, all check boxes & radio buttons turned blue. So here is dead simple solution for grayscale lovers;

迟到但请注意：在我将 Chrome 升级到 v/81 后，所有复选框和单选按钮都变为蓝色。所以对于灰度爱好者来说，这是一个非常简单的解决方案；

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

Transparency maybe: checkbox inside span

透明度可能：跨度内的复选框

<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>

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:

同意 iLoveTux ，应用太多东西（许多颜色和背景）没有任何效果，但这是开始工作的，将这些属性应用到它的 css：

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

and then css styling started working on checkbox :)

然后 css 样式开始处理复选框 :)
