我为我的网站创建了一个水平导航（菜单）栏。当我将窗口的大小重新调整为小于栏的大小时，菜单项会被包装。我希望菜单保持不变（也就是说，它应该保持水平），而不管窗口的大小，因为它通常可以在 Google 等网站上看到。我尝试了在各种论坛上发布的各种方式，包括这个，但对我没有任何帮助。下面我粘贴了菜单的 CSS 代码。
CSS CODE:
#cssmenu ul { margin: 0; padding: 0;}
#cssmenu li { margin: 0; padding: 0;}
#cssmenu a { margin: 0; padding: 0;}
#cssmenu ul {list-style: none;}
#cssmenu a {text-decoration: none;}
#cssmenu {height: 70px; background-color: #6699CC; box-shadow: 0px 2px 3px rgba(0,0,0,.4); }
#cssmenu > ul > li {
float: left;
margin-left: 30px;
position: relative;
}
#cssmenu > ul > li > a {
color: #FFFFFF;
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 18px;
line-height: 70px;
padding: 15px 20px;
-webkit-transition: color .15s;
-moz-transition: color .15s;
-o-transition: color .15s;
transition: color .15s;
}
#cssmenu > ul > li > a:hover {color: #00FF00; }
body.home li.home, body.tech li.tech {font-weight:bold; }
#cssmenu > ul > li > ul {
opacity: 0;
visibility: hidden;
padding: 16px 0 20px 0;
background-color: #FFFFFF;
text-align: left;

}
#cssmenu > ul > li:hover > ul {

}
#cssmenu > ul > li > ul:before{

#cssmenu ul ul a:hover {background-color: rgb(240,240,240);}
#cssmenu ul ul ul {
