仅使用 CSS 和 HTML 的自定义复选框 [英] Custom checkbox using only CSS and HTML
问题描述
我需要仅使用 html 和 CSS 创建一个自定义复选框.到目前为止,我有:
HTML/CSS:
.checkbox-custom {不透明度:0;位置:绝对;}.checkbox-自定义,.checkbox-custom-label {显示:内联块;垂直对齐:中间;边距:5px;光标:指针;}.checkbox-custom + .checkbox-custom-label:before {内容: '';背景:#fff;边框半径:5px;边框:2px 实心#ddd;显示:内联块;垂直对齐:中间;宽度:10px;高度:10px;填充:2px;右边距:10px;文本对齐:居中;}.checkbox-custom:checked + .checkbox-custom-label:before {内容: "";显示:内联块;宽度:1px;高度:5px;边框:纯蓝色;边框宽度:0 3px 3px 0;变换:旋转(45度);-webkit-transform:旋转(45度);-ms-transform:旋转(45度);边界半径:0px;边距:0px 15px 5px 5px;}
<input id="checkbox-1" class="checkbox-custom" name="checkbox-1" type="checkbox"><label for="checkbox-1" class="checkbox-custom-label">首选</label><div><input id="checkbox-2" class="checkbox-custom" name="checkbox-2" type="checkbox"><label for="checkbox-2" class="checkbox-custom-label">第二选择</label>
checked
复选框应该是一个带有方框的复选标记,而不仅仅是一个复选标记.在寻找答案时,我只发现了使用 UTF-8 字符或图像显示复选标记的情况.我无法将其中任何一个用于我想要完成的工作.我只能使用纯 CSS 和 HTML.有什么建议吗?

问题是您对方形边框和复选标记使用了相同的伪元素.简单的解决方案是继续使用 :before
伪元素作为边框,然后使用 :after
伪元素作为复选标记.
您必须绝对定位 :after
伪元素 相对 到父 .checkbox-custom
标签元素.
这是更新的代码:
.checkbox-custom {显示:无;}.checkbox-custom-label {显示:内联块;位置:相对;垂直对齐:中间;边距:5px;光标:指针;}.checkbox-custom + .checkbox-custom-label:before {内容: '';背景:#fff;边框半径:5px;边框:2px 实心#ddd;显示:内联块;垂直对齐:中间;宽度:10px;高度:10px;填充:2px;右边距:10px;}.checkbox-custom:checked + .checkbox-custom-label:after {内容: "";填充:2px;位置:绝对;宽度:1px;高度:5px;边框:纯蓝色;边框宽度:0 3px 3px 0;变换:旋转(45度);顶部:2px;左:5px;}
<h3>复选框</h3><div><input id="checkbox-1" class="checkbox-custom" name="checkbox-1" type="checkbox"><label for="checkbox-1" class="checkbox-custom-label">首选</label>
<div><input id="checkbox-2" class="checkbox-custom" name="checkbox-2" type="checkbox"><label for="checkbox-2" class="checkbox-custom-label">第二选择</label>
I need to create a custom checkbox using only html and CSS. So far I have:
HTML/CSS:
.checkbox-custom {
opacity: 0;
position: absolute;
}
.checkbox-custom,
.checkbox-custom-label {
display: inline-block;
vertical-align: middle;
margin: 5px;
cursor: pointer;
}
.checkbox-custom + .checkbox-custom-label:before {
content: '';
background: #fff;
border-radius: 5px;
border: 2px solid #ddd;
display: inline-block;
vertical-align: middle;
width: 10px;
height: 10px;
padding: 2px;
margin-right: 10px;
text-align: center;
}
.checkbox-custom:checked + .checkbox-custom-label:before {
content: "";
display: inline-block;
width: 1px;
height: 5px;
border: solid blue;
border-width: 0 3px 3px 0;
transform: rotate(45deg);
-webkit-transform: rotate(45deg);
-ms-transform: rotate(45deg);
border-radius: 0px;
margin: 0px 15px 5px 5px;
}
<div>
<input id="checkbox-1" class="checkbox-custom" name="checkbox-1" type="checkbox">
<label for="checkbox-1" class="checkbox-custom-label">First Choice</label>
</div>
<div>
<input id="checkbox-2" class="checkbox-custom" name="checkbox-2" type="checkbox">
<label for="checkbox-2" class="checkbox-custom-label">Second Choice</label>
</div>
The checked
checkbox should be a checkmark with the square bordered around it instead of just a checkmark. Searching for answers, I have only found cases where the checkmark is displayed using a UTF-8 character or an image. I am not able to use either of these for what I am trying to accomplish. I am only able to use plain CSS and HTML. Any suggestions?

The problem is that you are using the same pseudo element for the square border and the checkmark. The simple solution would be to continue using the :before
pseudo element for the border, and then use an :after
pseudo element for the checkmark.
You would have to absolutely position the :after
pseudo element relative to the parent .checkbox-custom
label element.
Here is the updated code:
.checkbox-custom {
display: none;
}
.checkbox-custom-label {
display: inline-block;
position: relative;
vertical-align: middle;
margin: 5px;
cursor: pointer;
}
.checkbox-custom + .checkbox-custom-label:before {
content: '';
background: #fff;
border-radius: 5px;
border: 2px solid #ddd;
display: inline-block;
vertical-align: middle;
width: 10px; height: 10px;
padding: 2px; margin-right: 10px;
}
.checkbox-custom:checked + .checkbox-custom-label:after {
content: "";
padding: 2px;
position: absolute;
width: 1px;
height: 5px;
border: solid blue;
border-width: 0 3px 3px 0;
transform: rotate(45deg);
top: 2px; left: 5px;
}
<h3>Checkboxes</h3>
<div>
<input id="checkbox-1" class="checkbox-custom" name="checkbox-1" type="checkbox">
<label for="checkbox-1" class="checkbox-custom-label">First Choice</label>
</div>
<div>
<input id="checkbox-2" class="checkbox-custom" name="checkbox-2" type="checkbox">
<label for="checkbox-2" class="checkbox-custom-label">Second Choice</label>
</div>
