我认为最简单的解决方案是像一些用户建议的那样重新设置复选框的样式。下面的CSS为我工作，只需要几行CSS，并回答OP问题:

input[type=checkbox] {
    -webkit-appearance: none;
    -moz-appearance: none;
    vertical-align: middle;
    width: 14px; 
    height: 14px;
    font-size: 14px;
    background-color: #eee;
}

input[type=checkbox]:checked:after {
    position: relative;
    bottom: 3px;
    left: 1px;
    color: blue;
    content: "\2713"; /* check mark */
}

正如这篇文章中提到的，缩放属性似乎在Firefox上不起作用，并且转换可能会导致不希望看到的效果。

在Chrome和Firefox上测试，应该适用于所有现代浏览器。只需根据需要更改属性(颜色、大小、底部、左侧等)。希望能有所帮助!

你可以在Safari中让复选框变大——这通常是对常规方法的抵抗——使用这个属性:

一个简单的解决方案是使用属性缩放:

输入[类型=“复选框”] { 变焦：1.5; } <输入类型=“复选框” />

使用这个CSS代码

input[type=checkbox]
{
  /* Double-sized Checkboxes */
  -ms-transform: scale(1.5); /* IE */
  -moz-transform: scale(1.5); /* FF */
  -webkit-transform: scale(1.5); /* Safari and Chrome */
  -o-transform: scale(1.5); /* Opera */
  transform: scale(1.5);
  padding: 10px;
}

您可以在下面的代码中更改高度和宽度

.checkmark { 位置:绝对的; 上图:0; 左:0; 高度:20 px; 宽度:20 px; border - radius: 5 px; 边框:1px实体#ff7e02; ｝ < div class = "检查" > <标签类= " container1 " >建筑/景观 <input type="checkbox" checked="checked"> < span class = "勾" > < / span > < / >标签 < / div >
