有3個div，第一個div有一個標誌，第二個有滑塊，第三個div是導航，我想我的導航div固定在視口的底部，當它到達頂部時變得粘稠。我用這個代碼實現了這一點。定位在視口底部的導航欄也始終保持在div的底部
nav{
position:absolute;
width:100%;
height: 56px;
background-color:#ffffff;
bottom:0px;
display:block;
border-bottom: 1px solid #ededed;
background: #FFF;
font-family: 'Cinzel', serif;
font-weight:600;
font-size: 10px;
line-height: 1.5;
letter-spacing: 2px;
}
的代碼運行良好，但是當瀏覽器的大小時，其位於底部的導航打破了佈局，因爲它涉及了滑蓋的，我想，當瀏覽器大小的div上述資產淨值的高度適應視口的高度，我想創建的效果的工作示例是here
#topbar{
display:block;
position: fixed;
width:100%;
height: 30px;
