緩解和緩解動畫對搜索欄不起作用

Question

我讓搜索按鈕在導航欄上輕鬆顯示和隱藏搜索欄，並輕鬆進出，但動畫不起作用，它不會給我控制檯中出現錯誤。我不會寫出整個html代碼，這是html的示例代碼。

$('.search-icon a').on("click", function(){ 
 
    $('body').addClass('show-search').children('.search-box-outer').slideDown(); 
 
    return false; 
 
}); 
 

 
$('.close-search').click(function(){ 
 
    $('.search-box-outer').removeClass('show-search').slideUp(); 
 
    return false; 
 
});

.search-box-outer { 
 
    position: fixed; 
 
    width: 100%; 
 
    height: 60px; 
 
    float: left; 
 
    background: #fff; 
 
    z-index: 99999999; 
 
    left: 0; 
 
    top: -60px; 
 
    transition: all 0.2s ease-in; 
 
} 
 

 
.search-box { 
 
    width: 100%; 
 
    position: relative; 
 
    padding-right: 60px; 
 
} 
 

 
.search-box .form-control, 
 
.search-box .form-control:focus { 
 
    height: 82px; 
 
    border: 0; 
 
    border-bottom: 1px solid #ccc; 
 
    box-shadow: none !important; 
 
    font-size: 24px; 
 
    border-radius: 0; 
 
} 
 

 
.close-search { 
 
    background-color: #fff; 
 
    color: #000; 
 
    width: 60px; 
 
    height: 82px; 
 
    float: left; 
 
    border-bottom: 1px solid #ccc; 
 
    position: absolute; 
 
    top: 0; 
 
    right: 0; 
 
    font-size: 24px; 
 
    line-height: 82px; 
 
    text-align: center; 
 
    transition: all 0.2s ease-out; 
 
} 
 

 
.show-search .search-box-outer { 
 
    top: 0; 
 
    position: relative; 
 
    z-index: 99999; 
 
    width: 100%; 
 
} 
 

 
.search-box-outer .container { 
 
    padding: 40; 
 
}

jQuery的

$('.search-icon a').on("click", function(){ 
     $('body').addClass('show-search').children('.search-box-outer').slideDown(); 
     return false;

.show-search .search-box-outer{ 
    top:0;

    z-index: 99999; 
    width: 100%; 
}
