            Your code checks the style property for the ptext element which refers only to inline styling. Since the height is applied by a CSS class and not as inline styling.



            As suggested by mattia you can add the height as inline styling from the get-go, or if you prefer to use CSS as you currently are, a possible solution is posed in this question.

                  On first time it goes inside the else block of your function.I solved adding style="height:0" on the


                  tag.



                  <div id="div1">
                  <div class="div2">
                  <h3>prova 1<button id="buttonst" onClick="showtext()">+</button></h3>
                  <p id="ptext" style="height:0">lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum,
                  lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, lorem ipsum, </p>
                  <script>
                  function showtext(){

                  var but = document.getElementById("buttonst");
                  var p = document.getElementById("ptext");
                  var div = document.getElementById("div1");
                  if (p.style.height === "0px"){

                  but.innerHTML = "v";
                  p.style.height = "200px";
                  div.style.backgroundColor = "aquamarine";
                  } else {

                  but.innerHTML = "+";
                  p.style.height = "0px";
                  div.style.backgroundColor = "beige";
                  }
                  }
                  </script>
                  </div>

                      Your code checks the style property for the ptext element which refers only to inline styling. Since the height is applied by a CSS class and not as inline styling.



                      As suggested by mattia you can add the height as inline styling from the get-go, or if you prefer to use CSS as you currently are, a possible solution is posed in this question.
