我在这个简单的页面上工作,我正在寻找仅使用引导程序代码对页面进行居中(如果可能的话)这就是我到目前为止所做的。我尝试使用col-xl-offset-4
,但没有工作。

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<div class="container">
<div class="jumbotron">
<div class="row vertical-center-row">
<div class="col-xl-6 col-xl-offset-4">
<h1 class="text-primary text-center">Marcell Treville</h1>
<h3 class="text-center"><em>This is a tribute page for the legendary painter "Marcell Treville"</em></h3>
<div class="thumbnail">
<img src="">
<p>this is some text describing the image</p>
<h2>Here's a timeline of Dr. Marcell Treville</h2>
<ul>
<li><strong>1995</strong> item one</li>

您无需使用抵消。 尝试将“文本中心”添加到此div
HTML
IBUFDS IBUFDS_[0].clk
(
.I (input1_reg[0]),
.IB (input1b_reg[0]),
.O (output_reg[0])
);
IBUFDS IBUFDS_[1].clk
(
.I (input1_reg[1]),
.IB (input1b_reg[1]),
.O (output_reg[1])
);
希望这会有所帮助

你想要偏移3,因为这将加起来为12.如果你偏移4,你将有4'空'col,接下来的6个div,以及2个'empty'cols。你想要的是3-6-3。你现在拥有的是4-6-2。
