Question

我正在尝试使用twitter bootstrap开发一个非常简单的网站。添加内容时，我注意到容器类的所有内容都向左移了一点，并添加了带有图像内容的行类的子div。容器div的填充/边距/宽度似乎没有变化，所以我真的不确定是什么影响了这个变化。

下面是HTML和CSS，如果你用类.row1和.row2注释掉div，可以看到问题。这样做会将容器类的内容返回到其常规位置。

Answer 1

您是否尝试为图片添加最大宽度？

.img1 img, .img2 img, .img3 img {
    border: 2px solid black;
    height: 240px;
    width: 240px;
    max-width:100%; /* Added these */
    max-height:100%; /* Added these */
}

Example on Bootply

当行包含图像内容时，Bootstrap容器向左移动
