如何在 html 和 css 中获得缩小到适合的导航栏
How do I get a shrink-to-fit navbar in html and css
我正在使用 HTML 和 CSS，但似乎无法找到一种方法让我的导航栏随 window 调整大小。当我缩小 window 时，我从我的导航栏中得到了一堆可怕的图标。有没有任何代码可以提供帮助？
这是我的代码：
navbar{position: absolute;
top: 145px;
left: 20px;
width: auto;
list-style-type: none;
background-color: #ff0000
}
navbar ul{
font-size:42px;
}
navbar li{
display: inline-block;
}
navbar a{
border-right:2px solid #000000;
color:#000000;
font-size:0.9em;
text-transform:uppercase
}
navbar li a{
text-decoration: none;
background-color: #ff0000;
color: #000001
height: 50px;
padding: 16px 12px;
border-spacing: 10px;
transition: 0.5s ease;
}
navbar li a:hover{
background-color: #000000;
color: #ff0000;
transition: 1.0s ease;
}
navbar li.active a{
background-color: #000000;
color: #ff0000;
}
