我正在使用Jquery可拖动组件向<p>中添加一个元素。
我遇到了以下问题：
IE浏览器显示效果不佳（见图像）。它显示的是all-scroll而不是Pointer。
这是由于以下CSS引起的
p.given {
display: flex;
flex-wrap: wrap;
}
我使用了以下 CSS 来正确显示 <p> 内容。如果我移除这个 CSS，可拖动的组件会出现在多个位置，有时候 <p> 的内容也会在放置组件后跳到下一行。你能否提出什么替代方案以替代 flex？我不能删除这个 CSS (p.given { display: flex; flex-wrap: wrap; })，因为如果我移除它，<p> 的内容就无法正确地自适应。请给我一个解决 IE 浏览器问题的方案。
