마우스가 올라간 그 요소의 자식요소(ul)의 높이를 구하고,
기존 header의 높이와 합산하여 header 높이를 변경한다.

▏setInterval 속성 활용
let progressBar = $('.progress-bar'),
bar = progressBar.find('.bar'),
rate = progressBar.find('.rate'),
targetNum = rate.attr('data-rate');
/*
bar의 너비가 targetNum의 값으로 늘어나도록 시간은 1.5초
대상.animate({css속성명:값, css속성명:값},시간);
*/
bar.animate({width:targetNum+'%'},1500);
let numAnimation = setInterval(function(){
let barCurrentWidth = Math.ceil(bar.width() / progressBar.width()*100);
rate.text(barCurrentWidth+'%');
if(targetNum == barCurrentWidth){
clearInterval(numAnimation);
}
console.log('작동')
},100);▏animate의 progress속성 활용
ex) 1번째 구현
let progressBar = $('.progress-bar'),
bar = progressBar.find('.bar'),
rate = progressBar.find('.rate'),
targetNum = rate.attr('data-rate');
/*
대상.animate({속성명:값, 속성명:값}시간,이징,할일);
대상.animate({opacity:1},{1500, 'swing', function(){}});
대상.animate({opacity:1},{
duration: 1500,
easing: 'swing',
progess: function(){..} //진행중 할일
complete: function(){..} //완료후 할일
});
*/
$({num:0}).animate({num:60},{
duration: 1500,
progress: function(){
let now = Math.ceil(this.num);
rate.text(now+'%');
}, // animate가 진행 중에 할일
complete:function(){
console.log('완성');
} // animate가 다 끝난 다음에 할일
});ex) 2번째 구현
/*
progress마다 각각 할일
변수명 bar에 각요소의 .bar,
변수명 rate에 각요소의 .rate,
변수명 rateNum 각 요소의 data-rate의 값을 할당
*/
progressBar.each(function(){
let bar = $(this).find('.bar'),

rateNum = rate.attr('data-rate');
bar.animate({width:rateNum+'%'}, 1500);
$({num:0}).animate({num:rateNum},{
duration:1500,
progress:function(){
let now = Math.ceil(this.num);
rate.text(now+'%');
