我有以下的CSS，它的效果很好。不过，我有大约五十里。有没有办法自动添加列和每列显示10？我试了左：float;但看起来很讨厌。我试过column-count：3列间距：10px但对李没有影响（只是改变ul的宽度）CSS - 如何继续在UL LI的第二列UL LI
我有jsFiddle的html和css，如果有帮助。 https://jsfiddle.net/zq54cb2b/
#cssmenu ul li {
padding: 7px 7px;
color: #000000;
background-color: #cce5ff;
border-bottom: 1px solid #f1f5f9;
}
如何使用flexbox？
#cssmenu ul {
display: flex;
flex-wrap: wrap;
}
#cssmenu ul li {
flex: 1 0 25%;
}

css在小提琴中工作，但不在共享点。 –
哪些浏览器和浏览器版本这是否需要在工作吗？ http://caniuse.com/#feat=multicolumn – BSMP
IE 11是我们公司的默认浏览器，但他们也允许铬和移动设备（主要是iPad） –
你能提供一个[mcve]来证明这个问题吗？如果我把你的CSS放在小提琴中，并为列添加规则 - 这里：https：//jsfiddle.net/MrLister/ax4g9ubk/ - 它在所有浏览器中都很好用。 –
