我设法在宽屏上显示:
这在狭窄的屏幕上:
如果仔细观察,窄屏幕中的图像在中心没有正确对齐,则会将其放在左侧。我想让它成为中心。
而且我也无法使图像填满所有空间,但仍有一些红色区域,这意味着它没有填满。
请帮助,我花了几个小时的研究,但仍然一无所获。
我看到一些保证金解决方案,但没有帮助。
我试图设置宽度,它居中但不会填充旋转木马的顶部和底部。而且它在狭窄的屏幕上变得很小。

您可以将图片设置为background-image
的css div
,而不是使用img
标记。然后设置background-size: cover;
:
div {
background-image: url(path/to/img/relative/to/css);
background-size: cover;
background-position: 50%;
}
这种方法的缺点是你需要指定div的宽度和高度,但是你使用的任何图像都会填充它,所以它应该是一个问题。

Bootstrap Carousel图像居中,适用于Bootstrap 3和4-alpha。
所需要的只是将样式text-align:center;
添加到您希望居中的轮播项目div。其他人将与左边对齐。
这使图像居中并且不会改变其大小。如果您需要使用图像填充整个轮播面板,只需将图像宽度更改为100%,它就会填充并居中(请参阅下面的代码中的第三张图片)。
这是直接来自Bootstrap 4 alpha的轮播示例。额外的样式是图像居中所需的全部(在这种情况下将'center'类添加到carousel-item div),并且可以使用各种方法实现。
