我想做一个复选框，只是稍大一点，并查看37Signals Basecamp的源代码，以找到以下解决方案-

您可以更改字体大小，使复选框略大:

font-size: x-large;

然后，你可以正确对齐复选框，这样做:

vertical-align: top;
margin-top: 3px; /* change to center it */

问题是Firefox不听宽度和高度。把它拆了，你就可以走了。

输入(type =复选框){ 宽度:25 px; 高度:25 px; -moz-appearance:没有; ｝ <label><input type="checkbox"> Test</label>

它有点丑(由于缩放)，但它适用于大多数更新的浏览器:

input[type=checkbox] { /* Double-sized Checkboxes */ -ms-transform: scale(2); /* IE */ -moz-transform: scale(2); /* FF */ -webkit-transform: scale(2); /* Safari and Chrome */ -o-transform: scale(2); /* Opera */ transform: scale(2); padding: 10px; } /* Might want to wrap a span around your checkbox text */ .checkboxtext { /* Checkbox text */ font-size: 110%; display: inline; } <input type="checkbox" name="optiona" id="opta" checked /> <span class="checkboxtext"> Option A </span> <input type="checkbox" name="optionb" id="optb" /> <span class="checkboxtext"> Option B </span> <input type="checkbox" name="optionc" id="optc" /> <span class="checkboxtext"> Option C </span>

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!
