我对Bootstrap很新,我在尝试对齐标题时遇到问题。根据屏幕截图,当我在“活动工作流程”标题上放置一个h6标签时,它会在其底部放置一个边距使其偏离中心。我浏览了dev工具中的所有样式,并且无法弄清楚如何添加这个边距。在这里寻找任何形式的见解。
编辑:尝试从H6标签上拉出边距,但填充仍然存在,添加了另一个图像显示。
代码:
<div class="row">
<div class="col-md-11">
<h6>Active Workflow</h6>
</div>

它是由Bootstrap添加的......
.h1, .h2, .h3, .h4, .h5, .h6 {
margin-bottom: 0.5rem;
}
您可以使用..
将其删除using margin utils<h6 class="mb-0">Active Workflow</h6>

bootstrap向标题元素(h1-h6)添加默认边距。您可以使用mb-0
<h6 class="mb-0">text<h6>

所以我不确定它为什么会起作用,但我注意到在另一个页面上我没有特别使用H6标签,我已将它添加到标签中。出于某种原因,这完美地隔离了它。一个h6标签,即使它上面有mb-0,仍然可以证明文本的正确性。

只有h6标签,该列的高度为23像素,标签为26。
