Suppose there is such a code as to make the rim of the button blue in it, and when pressed in the center, it was also blue.
input[type='radio'], label { cursor: pointer; } input[type='radio'] { height: 22px; width: 22px; } <p> <input type="radio" name="radio1" id="answer1" value="yes"> <label for="answer1">  Да</label> </p> <p> <input type="radio" name="radio1" id="answer2" value="no"> <label for="answer2">  Нет</label> </p>
