栏内的Bootstrap 4.1额外填充
过渡到引导程序4.1后遇到一些麻烦。我有水平卡可以在4.0-alpha中正常工作，但是现在还不行。下面的屏幕快照显示了两次尝试将水平卡片与大约75％的卡片文本和25％的右侧图像缩略图对齐的尝试。第一次尝试是两列裸露的骨头，第二次尝试来自示例here（请参阅卡的一半）。我倾向于简化维护，但是第二个示例显然看起来更好（如果删除边框颜色），但是在任何一种情况下，我都会在图像周围添加额外的填充，并且75:25的比例取决于图像的大小是不稳定的。如果可能的话，我想提供最快速响应的解决方案和可维护的解决方案（我知道...吃乞be的蛋糕）。
目标：将大小相等的水平卡片对齐在中心一栏中，每张卡片的文字文本大约占75％，图像的图片占25％。我希望能够根据所需图像的大小或div图像的大小来调整此比率。因此，如果我增加图像大小/最大宽度，它将增加图像列/伸缩行/其他内容，或者增加图像div将减少卡片文本div。但是无论原始图像大小如何，都应在该列中填充空白。
*此外，两张卡都在同一个父容器中，因此我不确定为什么其中一张比另一张更宽。

看过许多解决方案，但我不确定它们是否适用，因为它们要老得多且4.1太新了。

当前建议看起来几乎不错，但是当图像更改时，它似乎不符合设定的宽度。还是我不正确地使用data-src和src？
1 个答案:
答案 0 :(得分：1)
注意p-*类与col-*类不同。 “ p ”在这里代表“ 填充”，p-4不能代替col-4。
如果您想要75/25的比率，请在父级上使用row no-gutters，在直系子级上使用col-8和col-4。如果图像的原始宽度小于列宽，则通常不填充列。要填充该列，请给它
display:block; /* or d-block class */
width: 100%; /* or w-100 class */
height: auto; /* or h-auto class */
现在，列将保留比率，您可以从此开始使用边距或填充类。
请注意，col-*应该是.row或.row-fluid的 直子 。装订线系统是智能且响应迅速的，但是依赖于此标记。

如果要使用flexbox，请允许文本在可用空间中增长-宽度减去图片，这是flexbox首先为其创建的内容，请使用以下示例：

<div class="card flex-md-row mb-4 box-shadow h-md-250 m-3">
