如何減少CSS中<nav>標記的大小？我似乎無法弄清楚。我已經提供了下面我項目的所有代碼。我的代碼確實有PHP，但我已經刪除它，因爲它是不必要的。這裏是一個JSFiddle，如果你想在那裏預覽代碼。如何在html或css中設置<nav>的高度
HTML和CSS：
#top-menu {
top: 0;
position: fixed;
}
nav {

/*float: left;*/
width: 100%;
background: #1E1E1E;
/* display: table; */
margin: 0;
text-align: center;
height: 25px;
border: none;
border-width: 0;
margin: 0;
padding: 10px 10px;
}
