为什么元素没有在复选框中居中？
必须正好位于复选框的中间。
点击后，它应该是这样的:
尝试过:
left: 50%; top: 50%; - does not seem to work.
我不明白为什么单击复选框时会出现水平滚动。
overflow-x: hidden; - not a solution
代码:
* {
box-sizing: border-box;
user-select: none;
}
section {
display: flex;
flex-direction: column;
padding: 0.5em;
}
input[type='checkbox'] {
height: 0;
width: 0;
}
input[type='checkbox']+label {
position: relative;
display: flex;
margin: .6em 0;
align-items: center;
color: #9e9e9e;
}
input[type='checkbox']+label>ins {
position: absolute;
display: block;
bottom: 0;
left: 2em;
height: 0;
width: 100%;
overflow: hidden;
text-decoration: none;
}
input[type='checkbox']+label>ins>i {
position: absolute;
bottom: 0;
font-style: normal;
color: #000;
}
input[type='checkbox']+label>span {
display: flex;
justify-content: center;
align-items: center;
margin-right: 0.8em;
width: 1.2em;
height: 1.2em;
background: transparent;
border: 2px solid #E6ECF0;
border-radius: 3px;
cursor: pointer;
transition: all 250ms cubic-bezier(.4, .0, .23, 1);
}
input[type='checkbox']:checked+label>ins {
height: 100%;
}
input[type='checkbox']:checked+label>span {
border: .5em solid #7726E5;
}
input[type='checkbox']:checked+label>span:before {
content: "";
position: absolute;
box-shadow: inset 0px 0px 0px 5px rgba(0, 0, 0, 0.75);
border-radius: 2px;

老实说，它看起来非常适合我。出现水平滚动是因为您的黑色文本(显示在灰色文本之上)位于宽度为 100% 的元素内，但其父元素也包含复选框。我建议只是让原始标签的颜色更深，而不是使用第二层文本。
这里是一个编辑:
* { box-sizing: border-box; user-select: none; }
section{
display: flex;
flex-direction: column;
padding: 0.5em;
}
input[type='checkbox']{ height: 0; width: 0; }
input[type='checkbox'] + label{
position: relative;
display: flex;
margin: .6em 0;
align-items: center;
color: #9e9e9e;
}
input[type='checkbox'] + label > span{
display: flex;
justify-content: center;
align-items: center;
margin-right: 0.8em;
width: 1.2em;
height: 1.2em;
background: transparent;
border: 2px solid #E6ECF0;
border-radius: 3px;
cursor: pointer;
transition: all 250ms cubic-bezier(.4,.0,.23,1);
}
input[type='checkbox']:checked + label > span{
border: .5em solid #7726E5;
}
input[type='checkbox']:checked + label > span:before{
content: "";
position: absolute;
box-shadow: inset 0px 0px 0px 5px rgba(0,0,0,0.75);
border-radius: 2px;
}
input[type='checkbox']:checked + label {
color: unset;

</html>如果你想让复选框中间的白色方 block 更宽(就像你的 png 中的那样)，你应该在此处缩小边框:
input[type='checkbox']:checked + label > span{
border: .5em solid #7726E5;
}
