Stap 2, de lampen
Om de lamp te laten branden, plaatsen we code in het <script> </script> gedeelte.
function switchLight(color) {
if (color === 'red') {
document.getElementById("red").style.backgroundColor="red";
document.getElementById("orange").style.backgroundColor="darkgray ";
document.getElementById("green").style.backgroundColor="darkgray ";
document.getElementById("text").innerHTML="STOP";
}
}
