Answer 2

更好的方法是使用flexbox确保您的菜单可以填充页面的宽度。

  

Flexbox布局（灵活盒子）模块（目前是W3C最后调用工作草案）旨在提供一种更有效的方式来布置，对齐和分配容器中的项目之间的空间，即使它们的大小未知和/或动态的（因此单词＆＃34; flex＆＃34;）。

有关flexbox的详细参考，请参阅：https://css-tricks.com/snippets/css/a-guide-to-flexbox/

对于修复此问题的CSS，请参阅：http://jsfiddle.net/haveapk/berthtsv/

我首先将包含ul显示模式设置为flex（参见下面的代码）

display:-webkit-flex;
display:flex;

然后给孩子元素这些样式，所以他们都将是相同的大小

-webkit-flex:1;
flex:1;

如果你想要一个项目比其他项目更大，你可以改变它的flex样式。

Answer 3

请尝试下面的代码，我已经创建了cssmenu。这对你很有帮助。

HTML代码

 <div>
        <ul class="cssmenu">
            <li><a href="#">link 01</a></li>
            <li><a href="#">link 02</a></li>
            <li><a href="#">link 03</a></li>
            <li><a href="#">link 04</a></li>
            <li><a href="#">link 05</a></li>
        </ul>
    </div>

CSS代码

.cssmenu{
    padding:0;
    margin:0;
    display:inherit;
}

.cssmenu li{
    -webkit-flex:1;
    display:inherit;
    text-align:center;
    line-height:50px;
    background:#07275d;
    color:#ffffff;
    border:1px solid #000;
    -webkit-border-radius: 0 0 8px 8px;
    border-radius: 0 0 8px 8px;
}
.cssmenu li a{color:#fff; text-decoration:none}

@media (min-width: 767px){
    .cssmenu{display:flex;}
    .cssmenu li{display:inline-block;}

}
