具有一组 div 的图像的 CSS spritesheet

Question

我正在尝试为一堆盒子使用 spritesheet，我这样做的方式显然会多次调用图像(导致 spritesheet 无用，或者实际上更糟)。只是想知道如何才能更有效地调用图像一次

<div class="live-box-outer">
                <div class="live-box contact-highlight" id="phone">

                    <div class="overlay" style="display: none">
                        <h2>
                            Telephone Number</h2>
                        <div class="arrow">
                        </div>
                    </div>
                    <span>Our #</span>
                </div>
            </div>
            <div class="live-box-outer">
                <div class="live-box" id="mobile">
                    <div class="overlay" style="display: none">
                        <h2>
                            text mobile
                            functions</h2>
                        <div class="arrow">
                        </div>
                    </div>
                    <span>Mobile Sites</span>
                </div>
            </div>

还有我的风格:(这只是一个 sample ，我有大约9盒)

   #phone
{
     background-image:url('../img/Mountain.png');
     background-position: 0px 0;
    background-repeat:no-repeat; 
}
#mobile
{

    background-image:url('../img/Mountain.png');
     background-position: 0px -134px;
    background-repeat:no-repeat;
}

Answer 1

.live-box{
    background-image:url('../img/Mountain.png');
    background-repeat:no-repeat;
}

#phone
{
   background-position: 0px 0; 
}
#mobile
{
   background-position: 0px -134px;
}

应该可以
