Closed 3 years ago.

Hello Friends all I'm trying to do is change the background color of a checkbox. I tired many things but nothing works. Can some one help?

    input[type="checkbox"] {
      background: #3d404e;
      border: #7f83a2 1px solid;
   }

回答1:

I always use pseudo elements :before and :after for changing the appearance of checkboxes and radio buttons. it's works like a charm.

Steps

1. Hide the default checkbox using css rules like visibility:hidden or opacity:0 or position:absolute;left:-9999px etc.
2. Create a fake checkbox using :before element and pass either an empty or a non-breaking space '\00a0';
3. When the checkbox is in :checked state, pass the unicode content: "\2713", which is a checkmark;
4. Add :focus style to make the checkbox accessible.
5. Done

Here is how I did it.

.box {
  background: #666666;
  color: #ffffff;
  width: 250px;
  padding: 10px;
  margin: 1em auto;
}
p {
  margin: 1.5em 0;
  padding: 0;
}
input[type="checkbox"] {
  visibility: hidden;
}
label {
  cursor: pointer;
}
input[type="checkbox"] + label:before {
  border: 1px solid #333;
  content: "\00a0";
  display: inline-block;
  font: 16px/1em sans-serif;
  height: 16px;
  margin: 0 .25em 0 0;
  padding: 0;
  vertical-align: top;
  width: 16px;
}
input[type="checkbox"]:checked + label:before {
  background: #fff;
  color: #333;
  content: "\2713";
  text-align: center;
}
input[type="checkbox"]:checked + label:after {
  font-weight: bold;
}

input[type="checkbox"]:focus + label::before {
    outline: rgb(59, 153, 252) auto 5px;
}

<div class="content">
  <div class="box">
    <p>
      <input type="checkbox" id="c1" name="cb">
      <label for="c1">Option 01</label>
    </p>
    <p>
      <input type="checkbox" id="c2" name="cb">
      <label for="c2">Option 02</label>
    </p>
    <p>
      <input type="checkbox" id="c3" name="cb">
      <label for="c3">Option 03</label>
    </p>
  </div>
</div>

Much more stylish using :before and :after

body{
  font-family: sans-serif;  
}

.container {
    margin-top: 50px;
    margin-left: 20px;
    margin-right: 20px;
}
.checkbox {
    width: 100%;
    margin: 15px auto;
    position: relative;
    display: block;
}

.checkbox input[type="checkbox"] {
    width: auto;
    opacity: 0.00000001;
    position: absolute;
    left: 0;
    margin-left: -20px;
}
.checkbox label {
    position: relative;
}
.checkbox label:before {
    content: '';
    position: absolute;
    left: 0;
    top: 0;
    margin: 4px;
    width: 22px;
    height: 22px;
    transition: transform 0.28s ease;
    border-radius: 3px;
    border: 2px solid #7bbe72;
}
.checkbox label:after {
  content: '';
    display: block;
    width: 10px;
    height: 5px;
    border-bottom: 2px solid #7bbe72;
    border-left: 2px solid #7bbe72;
    -webkit-transform: rotate(-45deg) scale(0);
    -moz-transform: rotate(-45deg) scale(0);
    -ms-transform: rotate(-45deg) scale(0);
    transform: rotate(-45deg) scale(0);
    position: absolute;
    top: 12px;
    left: 10px;
}
.checkbox input[type="checkbox"]:checked ~ label::before {
    color: #7bbe72;
}

.checkbox input[type="checkbox"]:checked ~ label::after {
    -webkit-transform: rotate(-45deg) scale(1);
    -moz-transform: rotate(-45deg) scale(1);
    -ms-transform: rotate(-45deg) scale(1);
    transform: rotate(-45deg) scale(1);
}

.checkbox label {
    min-height: 34px;
    display: block;
    padding-left: 40px;
    margin-bottom: 0;
    font-weight: normal;
    cursor: pointer;
    vertical-align: sub;
}
.checkbox label span {
    position: absolute;
    top: 50%;
    -webkit-transform: translateY(-50%);
    transform: translateY(-50%);
}
.checkbox input[type="checkbox"]:focus + label::before {
    outline: 0;
}

<div class="container"> 
  <div class="checkbox">
     <input type="checkbox" id="checkbox" name="" value="">
     <label for="checkbox"><span>Checkbox</span></label>
  </div>

  <div class="checkbox">
     <input type="checkbox" id="checkbox2" name="" value="">
     <label for="checkbox2"><span>Checkbox</span></label>
  </div>
</div>
