为复选框使用背景图像

Question

我正在尝试设置一些复选框，以便在未选中时使用我拥有的一张图片，然后在选中时使用另一张图片。这是我当前的复选框：

<input type="checkbox" name="fordCheckBox" value="Ford">

我还使用以下 CSS 来设置每个复选框的背景图像。

input[type=checkbox][name=fordCheckBox] {
        background:url("https://pbs.twimg.com/profile_images/550291079719698432/LbybHjIh.jpeg") no-repeat;
        height: 25px;
        width: 25px;
        background-size: 50%;
    }

    input[type=checkbox][name=fordCheckBox]:checked {
        background:url("http://contentservice.mc.reyrey.net/image_v1.0.0/2267461") no-repeat;
        height: 25px;
        width: 25px;
        background-size: 50%;
    }

正如您在我的JSFiddle example 中看到的那样，图标大小正确，但它从未像应有的那样设置背景图像。有什么建议吗？

Answer 1

你可以用标签来做

   input[type=checkbox] {
    display:none;
}

input[type=checkbox] + label {
    display:inline-block;
    padding: 0 0 0 0px;
    background:url("https://pbs.twimg.com/profile_images/550291079719698432/LbybHjIh.jpeg") no-repeat;
    height: 125px;
    width: 125px;;
    background-size: 50%;
}

input[type=checkbox]:checked + label {
    background:url("http://contentservice.mc.reyrey.net/image_v1.0.0/2267461") no-repeat;
    height: 125px;
    width: 125px;
    display:inline-block;
    background-size: 50%;
}

HTML

<input type="checkbox" name="fordCheckBox" id="Ford" value="Ford">
<label for="Ford"></label>

Answer 2

您实际上不应该直接尝试更改复选框；某些浏览器将始终显示默认复选框。通常是通过为链接到输入 id 字段的复选框添加标签来完成的。例如：

<input type='checkbox' id='x' name='fordCheckBox'>
<label for='x'></label>

然后，您将复选框设置为 display: none，然后将实际的 CSS 应用到标签上。您的选择器应如下所示：input[type=checkbox]:checked + label

Answer 3

我使用了这个 CSS。在这个 CSS 中，当复选框被选中时，它会在复选框上放置一个刻度图像。它还默认更改复选框的大小、颜色和边框。

    input[type='checkbox'] {
        -webkit-appearance: none;
        width: 30px;
        height: 30px;
        background: white;
        border-radius: 5px;
        border: 2px solid #555;
        vertical-align:middle;
    }

    input[type='checkbox']:checked {
        background-image: url("Images/tick-sm.png");
        background-size: 90%;
        background-position: right center;
        background-repeat: no-repeat;
   }

用您自己的图片替换“Images/tick-sm.png”。

如果您也想为未选中状态使用不同的背景，请将第二个块的相同内容添加到第一个块并替换图像。
