<div class="box">
<div class="img"><img src="" /></div>
</div> in which box has a height of only 100px, which exceeds hiding, while img has a height of 1000px.At present, the effect you want to achieve is that each of the three pictures automatically scrolls up and down infinitely , and the mouse moves over the picture and stops scrolling. May I ask how to achieve it? Thank you very much! ~
