如何在 100% 的容器宽度中将一排相对居中的 <div> 居中

Question

我正在尝试将一排相对居中的 div 居中，这些 div 包含具有悬停过渡的图像，这些图像会变成另一个图像。

在使悬停过渡生效的过程中，我将每个 div 的容器定位为 position: relative。

随着窗口浏览器变小以使其具有响应性，我正在尝试使该行居中。发生的行为很奇怪。浏览器窗口中的图像变得太小而无法容纳该行图像将跳转到第二行，但它会在屏幕左侧稍稍停住，但不会停在中间。

是否有人对为什么会发生这种情况有解决方案或理解？理想情况下，我希望跳到第二行的图像居中。

这是我的代码：

Answer 1

无浮动

使用display:inline-block 而不是float:left。

text-align:center 对浮动元素没有任何影响，除了将其内容居中。

你可以看到它here 我覆盖了你的 css。
