      趁逢年味,整理一些小东西,希望大家能够喜欢;

      列举以下7个小demo来抛砖引玉

     1、多彩圆环

      利用 CSS3 的 background-image 和 border-radius 组合成的动画

      直接上代码:

      html

        <div id="item1">
            <div class="colorcircle shadow">
                <div></div>
                <div></div>
                <div></div>
                <div></div>
                <div></div>
                <div></div>
                <div class="centerWrap"></div>
            </div>
            <div id="colorCenter">
                do something
            </div>
        </div>

      CSS

     
        #item1 {
            margin: 2em;

            position: relative;
            overflow: hidden;
        }
        .colorcircle {
            width: 240px;
            height: 240px;
            margin: auto;

        .fr {
            float: right;
        }

      4、border-radius

      利用 CSS 的 border-radius

      html

        <div id="item4">
            <div class="title">border-radius</div>
            <div class="menuBtn">
                <div class="menuBtn_2">*</div>
                <ul class="menuBtn_3">
                    <li></li>
                    <li></li>
                    <li></li>
                </ul>
            </div>
            <ul class="menu">
                <li>1</li>
                <li>2</li>
                <li>3</li>
                <li>4</li>
                <li>5</li>
            </ul>
        </div>
        
    

      CSS

         #item4 {
            height: 300px;
            width: 64px;
            margin:  0 auto 100px;
        }
    
        #item4 .title {
            width: 150px;
            height: 120px;
            color: #888888;
            letter-spacing: 2px;
            text-align: center;
            line-height: 80px;
            transform: translate(-50%);
        }
        
        #item4  .menuBtn {
            width: 60px;
            height: 60px;
            border: 2px solid #333333;
            border-radius: 50%;
            position: relative;
            cursor: pointer;
        }
        
        #item4  .menuBtn .menuBtn_2 {
            width: 16px;
            height: 16px;
            color: #333333;

      7、文字多样效果

      利用:CSS text-shadow

      html

    <div id="item7">
        <div class="title">text-shadow</div>
        <div class="content1">“离开就是离开,分手就是分手,</div>
        <div class="content2">错对没有意义,不再合适的两人,</div>
        <div class="content3">与其耗尽对方养分,不如坦然聚散,各自相安”</div>
    </div>

      CSS

    #item7 {
            width: 400px;
            color: #fff;
            letter-spacing: 2px;
            text-align: center;
            line-height: 60px;
            font-weight: 700px;
            margin:  100px auto 200px;
        }
        #item7 .title{
            color: #888888;
            font-size: 26px;
        }
    
        #item7 .content1 {
            background-color: rgba(0,0,0,0.3);
            text-shadow: 0 0 2px #333333;
        }
        #item7 .content2 {
            color: #fff;
            background-color: #ED1C24;
            font-size: 24px;
            text-shadow: 0 0 2px #fff , 0 0 4px #fff;
        }
        #item7 .content3 {
            background-color: #009A61;
            text-shadow:    0 1px rgba(255, 0, 255, 0.9),
                            0 2px rgba(255, 0, 255, 0.8),
                            0 3px rgba(255, 0, 255, 0.7),
                            0 4px rgba(255, 0, 255, 0.6),
                            0 5px rgba(255, 0, 255, 0.5),
                            0 5px 10px black;
        }
        
    

      总结来说:CSS3的新特?#22278;?#19981;多, 缺乏的是创意创新灵感,将他们组合起来运用。年尾了,祝大家开开心心回家过大年、工作顺顺利利、合家美满。
