Question

当我在不使用变换的情况下为div设置动画时，一切都按预期工作。当我将变换添加到包含div时，内部div将移位到包含div的右侧。

<div class="container">
	<div class="bottom-container">
		<div class="b-holder">
			<div class="b-left">
				LEFT
			</div>
			<div class="b-right">
				RIGHT
			</div>
			<div class="b-center">
				CENTER
			</div>
		</div>
	</div>
</div>

＆＃13; 如果从b-holder中移除了变换，则所有div都正确定位。是什么导致这种情况发生？将变换添加到包含的div动画时，如何让左右和中心div保持绝对定位？

Answer 1

由于某些原因，添加变换时，div的内容使用绝对定位而不是固定定位。我通过更改每个动画的左侧值来解决这个问题。

CSS Transform取代了div子内容
