如何用白色更改复选框背景颜色

Question

我正在寻找一个解决方案，如何在复选框周围使用填充物或白色更改CSS背景颜色，我尝试使用保证金，填充高度等，但没有运气。因此，当用户单击复选框时，它将显示背景颜色，它正在工作，但是我想在复选框周围有白色填充，是否可能？

.checkbox {
  margin: 0 0 1em 2em;
}
.checkbox .tag {
  color: #595959;
  display: block;
  float: left;
  font-weight: bold;
  position: relative;
  width: 120px;
}
.checkbox label {
  display: inline;
}
.checkbox .input-assumpte {
  display: none;
}
.input-assumpte + label:after {
  background-color: #fafafa;
  border: 1px solid #cacece;
  box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05),
    inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05);
  display: inline-block;
  transition-duration: 0.3s;
  width: 16px;
  height: 16px;
  content: "";
  margin-left: 10px;
  padding: 5px;
}
.input-assumpte:checked + label:after {
  background-color: #0e4caa;
  padding: 5px;
}

<div class="checkbox">
							<input type="checkbox" class="input-assumpte" id="input-confidencial" />
							<label for="input-confidencial">Confidencial</label>
						</div>

Answer 1

正是您想要的是背景折叠，简单：

.checkbox {
    margin: 0 0 1em 2em;
}
.checkbox .tag {
    color: #595959;
    display: block;
    float: left;
    font-weight: bold;
    position: relative;
    width: 120px;
}
.checkbox label {
    display: inline;
}
.checkbox .input-assumpte {
    display: none;
}
.input-assumpte + label::after {
    background-color: #fafafa;
    border: 4px solid #0e4caa;
    background-clip: content-box;
    box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05), inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05);
    display: inline-block;
    transition-duration: 0.3s;
    width: 16px;
    height: 16px;
    content: "";
    margin-left: 10px;
    padding: 5px;
}
.input-assumpte:checked + label::after {
    background-color: #0e4caa;
    padding: 5px;
}

<div class="checkbox">
    <input type="checkbox" class="input-assumpte" id="input-confidencial" />
    <label for="input-confidencial">Confidencial</label>
</div>

也在Jsfiddle上。

背景CLIP CSS属性设置了元素的背景是否 延伸在其边框盒，填充盒或内容框的下方。

仅提到，还有一个使用outline的额外边框还有一个解决方案，但它扩展了元素：

.checkbox {
    margin: 0 0 1em 2em;
}
.checkbox .tag {
    color: #595959;
    display: block;
    float: left;
    font-weight: bold;
    position: relative;
    width: 120px;
}
.checkbox label {
    display: inline;
}
.checkbox .input-assumpte {
    display: none;
}
.input-assumpte + label::after {
    background-color: #fafafa;
    border: 4px solid #fafafa;
	outline: 4px solid #0e4caa;
    box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05), inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05);
    display: inline-block;
    transition-duration: 0.3s;
    width: 16px;
    height: 16px;
    content: "";
    margin-left: 10px;
    padding: 5px;
}
.input-assumpte:checked + label::after {
    background-color: #0e4caa;
    padding: 5px;
}

<div class="checkbox">
    <input type="checkbox" class="input-assumpte" id="input-confidencial" />
    <label for="input-confidencial">Confidencial</label>
</div>

Answer 2

您可以使用CSS box-shadow属性：

.checkbox {
  margin: 0 0 1em 2em;
}
.checkbox .tag {
  color: #595959;
  display: block;
  float: left;
  font-weight: bold;
  position: relative;
  width: 120px;
}
.checkbox label {
  display: inline;
}
.checkbox .input-assumpte {
  display: none;
}
.input-assumpte+label:after {
  background-color: #fafafa;
  border: 1px solid #cacece;
  box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05), inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05);
  display: inline-block;
  transition-duration: 0.3s;
  width: 16px;
  height: 16px;
  content: "";
  margin-left: 10px;
  padding: 5px;
}
.input-assumpte:checked+label:after {
  background-color: #0e4caa;
  padding: 5px;
  box-shadow: inset 0px 0px 0px 4px white
}

<div class="checkbox">
  <input type="checkbox" class="input-assumpte" id="input-confidencial" />
  <label for="input-confidencial">Confidencial</label>
</div>

Answer 3

插图的阴影应该足以满足此

box-shadow:0 1px 2px rgba(0, 0, 0, 0.05),
    inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05), inset 0 0 0 2px #0e4caa ,inset  0 0 0 4px white;

演示

.checkbox {
  margin: 0 0 1em 2em;
}
.checkbox .tag {
  color: #595959;
  display: block;
  float: left;
  font-weight: bold;
  position: relative;
  width: 120px;
}
.checkbox label {}
.checkbox .input-assumpte {
  display: none;
}
.input-assumpte+label:after {
  background-color: #fafafa;
  border: 1px solid #cacece;
  box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05), inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05);
  display: inline-block;
  transition-duration: 0.3s;
  width: 16px;
  height: 16px;
  content: "";
  margin-left: 10px;
  padding: 5px;
}
.input-assumpte:checked+label:after {
  background-color: #0e4caa;
  box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05), inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05), inset 0 0 0 2px #0e4caa, inset 0 0 0 4px white;
  padding: 5px;
}

<div class="checkbox">
  <input type="checkbox" class="input-assumpte" id="input-confidencial" />
  <label for="input-confidencial">Confidencial</label>
</div>

概述带有负偏移的概述也可能起作用：

  outline: solid white 2px;
  outline-offset: -5px;

.checkbox {
  margin: 0 0 1em 2em;
}
.checkbox .tag {
  color: #595959;
  display: block;
  float: left;
  font-weight: bold;
  position: relative;
  width: 120px;
}
.checkbox label {}
.checkbox .input-assumpte {
  display: none;
}
.input-assumpte+label:after {
  background-color: #fafafa;
  border: 1px solid #cacece;
  box-shadow: 0 1px 2px rgba(0, 0, 0, 0.05), inset 0px -15px 10px -12px rgba(0, 0, 0, 0.05);
  display: inline-block;
  transition-duration: 0.3s;
  width: 16px;
  height: 16px;
  content: "";
  margin-left: 10px;
  padding: 5px;
}
.input-assumpte:checked+label:after {
  background-color: #0e4caa;
  outline: solid white 2px;
  outline-offset: -5px;
  padding: 5px;
}

<div class="checkbox">
  <input type="checkbox" class="input-assumpte" id="input-confidencial" />
  <label for="input-confidencial">Confidencial</label>
</div>
