将HTML复选框的"勾号"标记替换为图像或任何其他符号

Question

如何Tick在HTML复选框中使用不同的图形(图像或其他符号)而不是默认标记.

我读了许多SO问题,但不能那样做.当我看到这个问题改变刻度线的颜色和这个.一切都是老问题.但它太复杂了.

有没有简单的方法来做到这一点.我希望现在有一个简单而好的方法吗？

实际上,使用CSS和伪元素这是一种简单的方法.我正在使用contentUnicode添加复选标记,但您也可以使用背景,只需确保定位正确.

这个实现只需要一个复选框本身,所以不需要额外的label等等......你的文本标签甚至可以在任何地方正常运行!

input[type="checkbox"]{
    -webkit-appearance: initial;
    appearance: initial;
    background: gray;
    width: 40px;
    height: 40px;
    border: none;
    background: gray;
    position: relative;
}
input[type="checkbox"]:checked {
    background: red;
}
input[type="checkbox"]:checked:after {
    /* Heres your symbol replacement - this is a tick in Unicode. */
    content: "\2713";
    color: #fff;
    /* The following positions my tick in the center, 
     * but you could just overlay the entire box
     * with a full after element with a background if you want to */
    position: absolute;
    left: 50%;
    top: 50%;
    -webkit-transform: translate(-50%,-50%);
    -moz-transform: translate(-50%,-50%);
    -ms-transform: translate(-50%,-50%);
    transform: translate(-50%,-50%);
    /*
     * If you want to fully change the check appearance, use the following:
     * content: " ";
     * width: 100%;
     * height: 100%;
     * background: blue;
     * top: 0;
     * left: 0;
     */
}

<input type="checkbox" />
