css3波紋特效、H5實現動態波浪

css3實現動態波紋特效,因爲css3裏面有過渡和動畫效果,如今利用css3實現動態波浪效果就很簡單了,直接使用transform來實現就ok, 使得translateX 產生偏移就能夠不斷實現循環動態效果,這樣就比傳統的flash來實現更爲簡單。並且對頁面也比較友好的。 css

好比實現如下的背景波紋特效:html

html5結構:html5

<div class="wrap__uc-hdinfo">
    <div class="inner flexbox">
        <div class="uimg">
            <span class="img"><img src="images/uimg/uimg-def.jpg" /></span>
        </div>
        <a class="info flex1" href="#">
            <label class="name">露娜</label>
            <label class="type mt-10">普通會員</label>
            <label class="tel ff-ar">18621535487</label>
        </a>
        <i class="arr iconfont icon-youjiantou c-fff fs-24"></i>
        <a class="lktel" href="tel:15888886666"><i class="iconfont icon-dianhua1"></i></a>
    </div>
    <!--css3實現波紋-->
    <div class="wrap__uc-waves">
        <i class="wave w1"></i>
        <i class="wave w2"></i>
    </div>
</div>
