我有以下HTML代码,它在DIV中显示水平可扩展菜单:
<div id='cssmenu'>
<ul>
<li class='active'><a href='about_us.aspx'>ABOUT US</a></li>
<li><a href="#">MISSION</a></li>
<li class='has-sub'><a href='#'>LEADERSHIP</a>
<ul>
<li><a href='#'>President</a></li>
<li><a href='#'>Medical Director</a></li>
<li><a href='#'>Board of Directors</a></li>
<li><a href='#'>Key Administrators</a></li>
</ul>
</li>
<li><a href='#'>WESTMED HISTORY</a></li>
<li><a href='#'>COMMUNITY SUPPORT</a></li>
</ul>
</div>
这是菜单的CSS:

margin: 0;

width: 100%;

}

border-radius: 0 0 0 3px;
}
#cssmenu ul ul li.has-sub > a:after {
content: '+';
position: absolute;
top: 50%;
right: 15px;
margin-top: -8px;
}
#cssmenu ul li:hover > a, #cssmenu ul li.active > a {

color: #FFF;
}
#cssmenu ul li.has-sub > a:after {

margin-left: 5px;
}
#cssmenu ul li.last ul {
left: auto;
right: 0;
}
#cssmenu ul li.last ul ul {
left: auto;
right: 99.5%;
}
对于桌面和大屏幕,它的效果很好,但每当我将其加载到平板电脑中时,图像就会转到下一行:
如何使菜单更流畅,以便根据cssmenu

查看flexbox,这可能是您的选择。
这个演示非常方便,您可以选择 space-around (如果我理解您的问题):http://codepen.io/chriscoyier/pen/FAbpm
