  <li class="blocks__name">CSS</li>
  <li class="blocks__name">jQuery</li>

</ul>
<ul class="blocks">
  <li class="blocks__block" id="1"></li>
  <li class="blocks__block" id="2"></li>
  <li class="blocks__block" id="3"></li>
  <li class="blocks__block" id="4"></li>
  <li class="blocks__block" id="5"></li>
</ul>

2. Create the content to be displayed in the fullscreen overlay.

<ul class="blocks-content">
  <li class="blocks-content__content">
    <div class="content__close"></div>

<script src="/path/to/cdn/jquery.slim.min.js"></script>

5. The main script to enable the expanding tab menu.

(function() {
  var bHeight, bWidth, block, bname, closeBtn, closeContent, content, expand, openContent, updateValues, wHeight, wWidth, xVal, yVal;

  block = $('.blocks__block');

  bname = $('.blocks__name');

  content = $('.blocks-content__content');

  closeBtn = $('.blocks__content-close');

  wHeight = $(window).outerHeight();

  wWidth = $(window).outerWidth();

  bHeight = block.outerHeight();

  bWidth = block.outerWidth();

  xVal = Math.round(wWidth / bWidth) + 0.03;

  yVal = wHeight / bHeight + 0.03;

  expand = function() {
    var aBlock, num;
    num = $(this).index();
    aBlock = block.eq(num);
    if (!aBlock.hasClass('active')) {
      bname.css('opacity', '0');
      aBlock.css({
        'transform': 'scale(' + xVal + ',' + yVal + ')',
        '-webkit-transform': 'scale(' + xVal + ',' + yVal + ')'
      });
      aBlock.addClass('active');
      openContent(num);
    }
  };

  openContent = function(num) {
    var aContent;
    content.css({
      'transition': 'all 0.3s 0.4s ease-out',
      '-webkit-transition': 'all 0.3s 0.4s ease-out'
    });
    aContent = content.eq(num);
    aContent.addClass('active');
  };

  closeContent = function() {
    bname.css('opacity', '1');
    content.css({
      'transition': 'all 0.1s 0 ease-out',
      '-webkit-transition': 'all 0.1s 0 ease-out'
    });
    block.css({
      'transform': 'scale(1)',
      '-webkit-transform': 'scale(1)'
    });
    block.removeClass('active');
    content.removeClass('active');
  };

  updateValues = function() {
    var yVal;
    var xVal;
    var bWidth;
    var bHeight;
    var wWidth;
    var wHeight;
    var aBlock;
    if (block.hasClass('active')) {
      aBlock = $('.blocks__block.active');
      wHeight = $(window).height();
      wWidth = $(window).width();
      bHeight = block.height();
      bWidth = block.width();
      xVal = Math.round(wWidth / bWidth) + 0.03;
      yVal = wHeight / bHeight + 0.03;
      aBlock.css({
        'transform': 'scale(' + xVal + ',' + yVal + ')',
        '-webkit-transform': 'scale(' + xVal + ',' + yVal + ')'
      });
    }
  };

  $(window).on('resize', updateValues);

  bname.on('click', expand);

  closeBtn.on('click', closeContent);

}).call(this);
