在ASCII艺术应该是居中的（因为它出现），但它应该排队，看起来像YAML。
the ascii art should be centered (as it appears) but it should line up and look like "YAML".

错误信息都应该排队，因为它在一个控制台。
the error message should all line up as it does in a console.

Reposing working answer from other question: http://stackoverflow.com/questions/1232096/how-to-horizonatally-center-a-floating-element-of-a-variable-width/1232297#1232297
假设这是自由浮动，将集中的元素一个div一个ID =内容......
Assuming the element which is floated and will be centered is a div with an id="content" ...
<body>
<div id="wrap">
<div id="content">
This will be centered
</div>
</div>
</body>
和应用下面的CSS
#wrap {
float: left;
position: relative;
left: 50%;
}
#content {
float: left;
position: relative;
left: -50%;
}
