Customizing the appearance of radio buttons is a common task for web developers and designers. One aspect that can be modified is the color of the radio buttons. This can be done by using the CSS attribute selector, which allows users to select elements based on their attributes. For example, to select all radio buttons, we can use the following CSS code −

As well, we can change the color of radio buttons by using the background-color property. This can be useful if we want to change the color of the entire button, including the button itself and any space surrounding it. For example, to change the background color of all radio buttons to blue, we can use the following CSS code −
input[type="radio"] {
background-color: blue;
}
