The :indeterminate selector in CSS is used to select any form elements that are in indeterminate state i.e a state that is neither checked nor unchecked. Elements targeted by this selector are:
- <input = “checkbox”> elements whose indeterminate property is set to true by JavaScript
- <input = “radio”> elements, when all radio buttons with the same name value in the form are unchecked
- <progress> elements in an indeterminate state
Example 1:
html
<!DOCTYPE html>
<html>
<head>
<title>
CSS :indeterminate selector
</title>
<style>
input:indeterminate+label {
background: green;
color: white;
padding: 4px;
}
input:indeterminate {
box-shadow: 0 0 1px 1px green;
}
</style>
</head>
<body style="text-align: center;">
