  position:relative;
  top:1px;
  font-weight:bold;
}
#abas li.selecionada a{
  padding-top: 11px

.conteudo{
  display:block;
  padding:10px;
  border: 1px solid #CCCCCC;

}

3. Finally, add the following JavaScript code and done.

var abas = document.getElementById("abas");
var conteudos = document.getElementById("conteudos");

/* Essa função retira a classe "selecionada" e esconde a DIV com o conteúdo visível */
function limparSelecao(){
  abas.getElementsByClassName("selecionada")[0].classList.remove("selecionada");
  conteudos.getElementsByClassName("visivel")[0].classList.remove("visivel");
}

/* Essa é executada quando alguma das abas é clicada */
abas.addEventListener("click", function(event){
  var abaClicada = event.target.id;
  var itemSelecionado = abaClicada.substring(abaClicada.lastIndexOf("_"));

  /* Chama função que tira a seleção do item atual */
  limparSelecao();

  /* Insere a classe "selecionada" na nova aba visível */
  event.target.parentElement.classList.add("selecionada");

  /* Insere a classe "visivel" para o conteúdo da aba selecionada */
  conteudos.querySelector("#conteudo"+ itemSelecionado).classList.add("visivel");
