好看的CSS效果

好看的效果

1.复选框：
思路是使用复选框并进行隐藏，然后自己写一个div，并且用:before来放进div复选框这,不少地方采用绝对定位,在:checked时更改对应颜色。

    <div class="container">
      <h2>To it</h2>
      <ul>
        <li>
          <input type="radio" id="f-option" name="selector" />
          <label for="f-option">Pizza</label>
          <div class="check"></div>
        </li>

        <li>
          <input type="radio" id="s-option" name="selector" />
          <label for="s-option">Bacon</label>
          <div class="check">
            <div class="inside"></div>
          </div>
        </li>

        <li>
          <input type="radio" id="t-option" name="selector" />
          <label for="t-option">Cats</label>
          <div class="check">
            <div class="inside"></div>
          </div>
        </li>
      </ul>
    </div>

body,html{
    height: 100%;
    background: #222222;
    font-family: 'lato', sans-serif;
}
.container{
    display: block;
    position: relative;
    margin: 40px auto;
    height: auto;
    width: 500px;
    padding: 20px;
}

h2{
    color: #AAAAAA;
}

.container ul{
    list-style: none;
    margin: 0;
    padding: 0;
    overflow:auto;
}

ul li{
    color:#AAAAAA;
    display: block;
    position: relative;
    float: left;
    width: 100%;
    height: 100px;
    border-bottom: 1px solid #333;
}
ul li input[type=radio]{
    position: absolute;
    visibility: hidden;
}
ul li label{
    display: block;
    position: relative;
    font-weight: 300;
    font-size: 1.35em;
    padding: 25px 25px 25px 80px;
    margin: 10px auto;
    height: 30px;
    z-index: 9;
    cursor: pointer;
    transition: all 0.25s linear;
}

ul li:hover label{
    color: #fff;
}
ul li .check{
    display: block;
    position:absolute;
    border: 5px solid #AAAAAA;
    border-radius: 100%;
    height: 25px;
    width: 25px;
    top: 30px;
    left: 20px;
    z-index: 5;
    transition: border .25s linear;
    -webkit-animation: border .25s linear;
}

ul li:hover .check{
    border: 5px solid #fff;
}
ul li .check::before{
    display: block;
    position:absolute;
    content: '';
    border-radius: 100%;
    height: 15px;
    width: 15px;
    top: 5px;
    left: 5px;
    margin: auto;
    transition: all 0.25s linear;
}
input[type=radio]:checked ~ .check{
    border:5px solid #0DFF92
}
input[type=radio]:checked ~.check::before{
    background: #0DFF92;
}
input[type=radio]:checked ~ label{
    color: #0DFF92;
}

对应效果:

2.菜单栏：使用复选框,设置为透明,使用三条span实现图案，然后三个span可以通过transform来定义旋转角度以及设置变换原点，然后使用选择器三条杆的选择方向不同.

<nav role="navigation">
  <div id="menuToggle">
    <input type="checkbox"/>
    <span></span>
    <span></span>
    <span></span>
    <ul id="menu">
      <a href="#"><li>Home</li></a>
      <a href="#"><li>About</li></a>
      <a href="#"><li>Info</li></a>
    </ul>
  </div>
</nav>
