    <button class="tabs-buttons__btn  btn-js">Tab 2</button>
    <button class="tabs-buttons__btn  btn-js">Tab 3</button>
  </div>
  <div class="tabs-sections">

    </div>
    <div class="tabs-sections__section  tab-js">

    </div>
  </div>
</main>

.tab-active-js { display: block; }
.tabs-header {
  font-size: 25px;
  text-align: center;
  margin: 3rem auto;
}
.centering-layer {
  width: 100%;
  max-width: 800px;
  margin: 2rem auto;
}
.tabs-buttons { font-size: 14px; }
.tabs-buttons__btn {
  display: block;
