           </li>
           <li>
               <a href="">
                   <i class="fa fa-comments-o"></i>
                   <strong>Blog</strong>
                   <small>what they say</small>
               </a>
               <ul>
                   <li><a href="#"><i class="fa fa-globe"></i>Mission</a></li>
                   <li>
                       <a href="#"><i class="fa fa-group"></i>Our Team</a>
                       <ul>
                           <li><a href="#"><i class="fa fa-female"></i>Leyla Sparks</a></li>
                           <li>
                               <a href="#"><i class="fa fa-male"></i>Gleb Ismailov</a>
                               <ul>
                                   <li><a href="#"><i class="fa fa-leaf"></i>About</a></li>
                                   <li><a href="#"><i class="fa fa-tasks"></i>Skills</a></li>
                               </ul>
                           </li>
                           <li><a href="#"><i class="fa fa-female"></i>Viktoria Gibbers</a></li>
                       </ul>
                   </li>
                   <li><a href="#"><i class="fa fa-trophy"></i>Rewards</a></li>
                   <li><a href="#"><i class="fa fa-certificate"></i>Certificates</a></li>
               </ul>
           </li>
           <li>
               <a href="">
                   <i class="fa fa-picture-o"></i>
                   <strong>Portfolio</strong>
                   <small>sweet home</small>
               </a>
           </li>
           <li>
               <a href="">
                   <i class="fa fa-envelope-o"></i>
                   <strong>Contacts</strong>
                   <small>drop a line</small>
               </a>
           </li>
           <li class="float">
               <a class="search">
                   <input type="text" value="search ...">
                   <button><i class="fa fa-search"></i></button>
               </a>
               <a href="" class="search-mobile">
                   <i class="fa fa-search"></i>
               </a>
           </li>
       </ul>
   </nav>

这里用ul构造了菜单的基本结构。

接下来就利用CSS3代码来实现菜单的下拉和动画效果。

这是鼠标滑过菜单项时的动画代码:

.mcd-menu li a i, .mcd-menu li a strong, .mcd-menu li a small {
 position: relative;
 
 transition: all 300ms linear;
 -o-transition: all 300ms linear;
 -ms-transition: all 300ms linear;
 -moz-transition: all 300ms linear;
 -webkit-transition: all 300ms linear;
}
.mcd-menu li:hover > a i {
   opacity: 1;
   -webkit-animation: moveFromTop 300ms ease-in-out;
   -moz-animation: moveFromTop 300ms ease-in-out;
   -ms-animation: moveFromTop 300ms ease-in-out;
   -o-animation: moveFromTop 300ms ease-in-out;
   animation: moveFromTop 300ms ease-in-out;
}
.mcd-menu li:hover a strong {
   opacity: 1;
   -webkit-animation: moveFromLeft 300ms ease-in-out;
   -moz-animation: moveFromLeft 300ms ease-in-out;
   -ms-animation: moveFromLeft 300ms ease-in-out;
   -o-animation: moveFromLeft 300ms ease-in-out;
   animation: moveFromLeft 300ms ease-in-out;
}
.mcd-menu li:hover a small {
   opacity: 1;
   -webkit-animation: moveFromRight 300ms ease-in-out;
   -moz-animation: moveFromRight 300ms ease-in-out;
   -ms-animation: moveFromRight 300ms ease-in-out;
   -o-animation: moveFromRight 300ms ease-in-out;
   animation: moveFromRight 300ms ease-in-out;
}</p> <p>.mcd-menu li:hover > a {
 color: #e67e22;
}

以下定义了鼠标滑过后文字图标滑过的动画,分别是从顶部划入,从左侧划入,从右侧划入:

@-webkit-keyframes moveFromTop {
   from {
       opacity: 0;
       -webkit-transform: translateY(200%);
       -moz-transform: translateY(200%);
       -ms-transform: translateY(200%);
       -o-transform: translateY(200%);
       transform: translateY(200%);
   }
   to {
       opacity: 1;
       -webkit-transform: translateY(0%);
       -moz-transform: translateY(0%);
       -ms-transform: translateY(0%);
       -o-transform: translateY(0%);
       transform: translateY(0%);
   }
}
@-webkit-keyframes moveFromLeft {
   from {
       opacity: 0;
       -webkit-transform: translateX(200%);
       -moz-transform: translateX(200%);
       -ms-transform: translateX(200%);
       -o-transform: translateX(200%);
       transform: translateX(200%);
   }
   to {
       opacity: 1;
       -webkit-transform: translateX(0%);
       -moz-transform: translateX(0%);
       -ms-transform: translateX(0%);
       -o-transform: translateX(0%);
       transform: translateX(0%);
   }
}
@-webkit-keyframes moveFromRight {
   from {
       opacity: 0;
       -webkit-transform: translateX(-200%);
       -moz-transform: translateX(-200%);
       -ms-transform: translateX(-200%);
       -o-transform: translateX(-200%);
       transform: translateX(-200%);
   }
   to {
       opacity: 1;
       -webkit-transform: translateX(0%);
       -moz-transform: translateX(0%);
       -ms-transform: translateX(0%);
       -o-transform: translateX(0%);
       transform: translateX(0%);
   }
}

css的基本语法是什么

css的基本语法是:

1、css规则由选择器和一条或多条声明两个部分构成;

2、选择器通常是需要改变样式的HTML元素;

3、每条声明由一个属性和一个值组成;

4、属性和属性值被冒号分隔开。
