选中后,自定义复选框会略微移动

标签: html css checkbox

我修改了项目中的复选框,看起来与设计的其余部分更加一致,但是我遇到了一个问题:每当选中时,复选框的标签会略微移动。

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

input[type="checkbox"]+label:before {
  position: relative;
  content: " ";
  display: inline-block;
  width: 22px;
  height: 22px;
  border: 1px solid grey;
  top: 4px;
  margin: 0 10px 0 0;
}

input[type="checkbox"]:checked+label:before {
  position: relative;
  content: "✔";
  display: inline-block;
  width: 22px;
  height: 22px;
  border: 1px solid grey;
  top: 4px;
  margin: 0 10px 0 0;
}
<input type="checkbox" />
<label>Click to accept</label>

结果如下:

如果我选择它会发生什么:

我做错了什么?

要修复“移动”,您需要:

  • vertical-align: some value中设置label::before我选择bottom

并且要对齐“✔”(如果它没有 - 代码片段不是),你需要:

  • text-align:center
  • 中添加line-height:22pxheight(与:checked+label::before相同)

我也删除了重复的属性,没有必要

注意:您错过for中的label属性以匹配输入中的id,否则您无法点击伪checkbox,只能在label

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

input[type="checkbox"]+label::before {
  position: relative;
  content: " ";
  display: inline-block;
  vertical-align: bottom;
  width: 22px;
  height: 22px;
  border: 1px solid grey;
  top: 4px;
  margin: 0 10px 0 0;
}

input[type="checkbox"]:checked+label::before {
  content: "✔";
  text-align: center;
  line-height: 22px;
}
<input id="input" type="checkbox" />
<label for="input">Click to accept</label>

我使用了一个flexbox标签来垂直对齐项目。选中复选框后添加text-align:center可确保标记水平居中。

&#13;
&#13;
label {
  display: flex;
  align-items: center;
}

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

input[type="checkbox"]+label:before {
  content: " ";
  display: inline-block;
  width: 22px;
  height: 22px;
  border: 1px solid grey;
  margin-right: 0.5em;
}

input[type="checkbox"]:checked+label:before {
  content: "✔";
  display: inline-block;
  width: 22px;
  height: 22px;
  border: 1px solid grey;
  margin-right: 0.5em;
  text-align: center;
}
&#13;
<input type="checkbox" id="accept" />
<label for="accept">Click to accept</label>

你可以尝试这个,这是有效的

&#13;
&#13;
input[type="checkbox"] {
      position: absolute;
    width: 100%;
    height: 100%;
    opacity: 0;
  }

  input[type="checkbox"] + label:before {
        position: relative;
    content: " ";
    display: inline-block;
    width: 22px;
    height: 22px;
    border: 1px solid grey;
    top: 4px;
    margin: -8px 10px 0 0;
    vertical-align: middle;
  }

  input[type="checkbox"]:checked + label:before {
     content: "✔";
    text-align: center;
    line-height: 22px;
  }
&#13;
 <input type="checkbox"/>
 <label>Click to accept</label>
