我确实有这种情况: [![在此处输入图片描述] [1]] [1]
我想拥有的是:
数字1:使列宽适合内容,在这种情况下,适合图像。
数字2:使列宽适合文本“内容标题”
数字3:适合此列的宽度,例如“其余宽度到末端”。所以要灵活。
我的HTML:
<div class="container-fluid">
<div class="jumbotron">
<div class="row">
<div class="col-xl-3 .mx-auto text-center">
<div class="row">
<div class="col-xl-1 bg-dark">
<img src="img/01_number_in_circular.svg" alt="Step 1">
</div>
<div class="col-xl-11 bg-success">
<h2>Title of Content</h2>
<p>Description Text in short form.</p>
</div>
</div>
</div>
<div class="col-xl-9 bg-info">
Column 3
</div>
</div>
</div>
我也尝试使用col-xl-*
,但是它不起作用。
我可以申请一门课吗? 我希望你能帮帮我。预先谢谢你。

下面有一个有效的示例(在“全窗口”模式下运行shippet)。基于https://getbootstrap.com/docs/4.0/layout/grid/
结果:
.col1 {
background-color: red;
}
.col2 {
background-color: green;
}
.col3 {
background-color: yellow;
}
