我有以下问题：我的页面有一个包含项目的图像。我将隐藏的 div 放在项目上以创建鼠标悬停效果。我用相对位置进行 div 的定位。一切正常，但我在页面末尾有一个空白区域和一个滚动条:(
<div style="height: 620px;">
<?php echo image_tag('startpage/bg.png', array('style' => 'width: 124px; height: 620px; border:0;'))?><?php echo image_tag('startpage/startpage.png', array('style' => 'border:0;'))?><?php echo image_tag('startpage/bg.png', array('style' => 'width: 124px; height: 620px; border:0;'))?>
