How to apply 2 different colors to a checkbox in css?

March 10, 2023

I am using checkboxes on my page. It works fine. However I want one checkbox with light blue color and another with light yellow. Currently both checkboxes are light blue. How can I make another one light yellow?

Here is what I have.

input[type=checkbox] {
  position: relative;
  cursor: pointer;
margin-right: 10px;
}
input[type=checkbox]:before {
  content: "";
  display: block;
  position: absolute;
  width: 16px;
  height: 16px;
  top: 0;
  left: 0;
  border: 1px solid #99AFC1;
  border-radius: 3px;
  background-color: lightblue;
  padding: 1px;
}
input[type=checkbox]:checked::before {
  background-color: lightblue;
}

input[type=checkbox]:checked::after {
  content: "";
  display: block;
  width: 5px;
  height: 10px;
  border: solid #ffffff;
  border-width: 0 2px 2px 0;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
  position: absolute;
  top: 2px;
  left: 6px;
}

<p><label><input type="checkbox" class="filter" value="Test1">Test1</label> <label><input type="checkbox" class="filter" value="Test2">Test2</label></p>

>Solution :

Just give a class for the ones you want to be lightyellow.

input[type=checkbox] {
  position: relative;
  cursor: pointer;
margin-right: 10px;
}
input[type=checkbox]:before {
  content: "";
  display: block;
  position: absolute;
  width: 16px;
  height: 16px;
  top: 0;
  left: 0;
  border: 1px solid #99AFC1;
  border-radius: 3px;
  background-color: lightblue;
  padding: 1px;
}
input[type=checkbox]:checked::before {
  background-color: lightblue;
}

input[type=checkbox]:checked::after {
  content: "";
  display: block;
  width: 5px;
  height: 10px;
  border: solid #ffffff;
  border-width: 0 2px 2px 0;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
  position: absolute;
  top: 2px;
  left: 6px;
}
.difcol:before, .difcol:checked::before, .difcol:checked::after {
  background-color: lightyellow !important;
}
.difcol::after {
  border-color: lightblue !important;
}

<p><label><input type="checkbox" class="filter" value="Test1">Test1</label> <label><input type="checkbox" class="filter difcol" value="Test2">Test2</label></p>

I had to change the checkmark color too so you could see it, and I called the class "difcol" meaning "different color".

To avoid using the !important property, you may want to not be putting background-color: lightblue; in with the other class, but in its own as well maybe.
