对于section中使用背景图片有没有什么好的方法？

不知道我的方法有什么可以改进的？ 我在html中添加了：

    <section class="panel panel1" data-section-name="second">
        <div class="inner"><div class="vertical-center">2</div></div>
    </section>
    <section class="panel panel2" data-section-name="third">
        <div class="inner"><div class="vertical-center">3</div></div>
    </section>
    <section class="panel panel3" data-section-name="fourth">
        <div class="inner"><div class="vertical-center">4</div></div>
    </section>

css file like below： div#home_img { background: url("../bg.png") no-repeat center; }

add a line into jQuery.Scrollify.js $this.find("#home_img").css({"height": portHeight});

<div class="inner"><div class="vertical-center"><div id="home_img"></div></div></div>
