Debounce

var titleHeight = debounce( () => { //active the function every 250ms to improve website performance
  var maxTitleHeight = Math.max.apply( null, $( '.__tag .__details h3' ).map( function () {
    return $( this ).height();
  } ).get() );

  if( window.innerWidth > 548 ) {
    $( '.__tag .__details h3' ).height( maxTitleHeight );
  } else {
    $( '.__tag .__details h3' ).height( 'auto' );
  }
}, 250);

titleHeight();
window.addEventListener( 'resize', titleHeight );
