我正在编写代码，以使用按钮设置表情符号列表。我对表情符号图像有问题，因为当我控制div块的宽度大小以防止图像溢出时，它们会溢出div块。

这是图片：

Here是JSFiddle链接。

我已经尝试过：

overflow:hidden;

我也尝试过这个：

width: 100%;
height: 100%; 
overflow-y: scroll;

这是完整的代码：

  </div>
</div>

我希望实现的是每次将图像移动到div块上方的位置，以便图像显示在新行中以防止溢出。我不知道该怎么做，因为我尝试了几种不同的方法，所以请您举个例子，说明如何将图像移到新行以防止div块溢出？

谢谢。

您需要为此应用word-wrap和white-space，

.a8m {

    padding: 2px;
    text-align: center;
    vertical-align: middle;
    margin: 4px;
    cursor: pointer;
    background: transparent;
    border: none;
    font-size: 1px;
    word-wrap: break-word;
    white-space: initial;

}

希望它对您有帮助:)

只需尝试一下：

图释的父div应该显示为FLEX 例如：

display:flex;（这将横向排列图释） flex-wrap:wrap;（这会使表情符号到达边缘时进入新的一行）
