Tela de avaliação responsiva utilizando CSS e Javascript

Hi Maila it's a nice solution. I only found a detail: If the user does not select any rating and presses submit, the script shows the thank you card. It must show a warning or a message. You can solve this by declaring ex as a global variable, calling from the HTML only the hide function, and adding a check inside it. Something like this...

var ex = 0;

function esconde(el) {

 if( ex == 0 ){
  alert("message");
}else{
     var display = document.getElementById(el).style.display;
     if(display == "none")
          document.getElementById(el).style.display = 'block';
      else
      document.getElementById(el).style.display = 'none';
      mostra(el);
 }

}

I didn't test it so it may have some error but that would be the idea... I hope I have helped, regards 😉
