css3制作大型导航
发布于
白牙
白牙同学好久都没有做练习了，今天为大家带来一个CSS3制作的简单大型导航，运用到的CSS3属性包括圆角border-radius、渐变、盒子和文字阴影等等。通过前面的案例，相信大家已经对这些CSS3常用属性已经有一定了解了。本来这个案例原意是想向大家展示CSS3的mutil column属性族的运用，但因为当前除了chrome以外的各个浏览器对它的支持并不是很好，所以也没有什么新颖的地方，有兴趣或者像学习导航制作的就往下看吧~不足之处和建议也希望大家能在下方提出~！
HTML结构
结构主要分为上方商标部分和下方菜单按钮部分
<div class="main-menu">
<div class="brand">
<a href="#" class="logo">YOUR LOGO</a>
<div class="btn-group">
<button type="button" class="sign-in">Sign in</button><button type="button" class="register">Register</button>
</div>
<div class="search-field">
<input type="search" placeholder="Search" />
<a class="search-icon">s</a>
</div>
</div>
<ul class="nav clearfix">
<li><a href="#">NFL</a></li>
<li><a href="#">MBL</a></li>
......
<li>
<a href="#">MORE</a>
<ul class="more-sport">
<span class="header">Sports</span>
<li>
<a href="#">Aussie Football</a>
<a href="#">MSL</a>
<a href="#">CFL</a>
<a href="#">NCAA Baseball</a>
<a href="#">Cricket</a>
<a href="#">Olympics</a>
</li>
<li>
......
</li>
<li>
......
</li>
<span class="footer"> Last update: Today,28 September,12 minutes ago <a href="#">ALL SPORTS</a> </span>
</ul>
</li>
</ul>
</div>
