在上篇文章给大家介绍了BootStrap3学习笔记(一)之网格系统
对于标题，Bootstrap已经修改了h1--h6的样式，如果需要副标题，还可以在其中使用small标记
<h1>h1. Bootstrap heading <small>Secondary text</small></h1> <h2>h2. Bootstrap heading <small>Secondary text</small></h2> <h3>h3. Bootstrap heading <small>Secondary text</small></h3> <h4>h4. Bootstrap heading <small>Secondary text</small></h4> <h5>h5. Bootstrap heading <small>Secondary text</small></h5> <h6>h6. Bootstrap heading <small>Secondary text</small></h6>
如果页面中有一个需要与众不同的h1，则可以将其包含在样式为“page-header的div中。
<div class="page-header"> <h1>Twitter Bootstrap <small>An intuitive front-end framework</small></h1> </div>
Bootstrap默认字体大小为14px，行高1.428，段落间距10px，如果某个段落需要醒目一点，可是有'lead'类
使用text-*类，可以很方便的设定文本的水平对齐方式
<p class="text-left">Left aligned text.</p> <p class="text-center">Center aligned text.</p> <p class="text-right">Right aligned text.</p> <p class="text-justify">Justified text.</p> <p class="text-nowrap">No wrap text.</p>
HTML中的文字格式标记在Bootstrap中都可以使用
<p><b>This is bold text</b></p> <p><big>This is big text</big></p> <p><code>This is computer code</code></p> <p><em>This is emphasized text</em></p> <p><i>This is italic text</i></p> <p><mark>This is highlighted text</mark></p> <p><small>This is small text</small></p> <p><strong>This is strongly emphasized text</strong></p> <p>This is <sub>subscript</sub> and <sup>superscript</sup></p> <p><ins>This text is inserted to the document</ins></p> <p><del>This text is deleted from the document</del></p>
字母格式转换类可以很好的完成需要的转换：
<p class="text-lowercase">The quick brown fox jumps over the lazy dog.</p> <p class="text-uppercase">The quick brown fox jumps over the lazy dog.</p> <p class="text-capitalize">The quick brown fox jumps over the lazy dog.</p>
颜色是传递内容重要性的有力方式，Bootstrap提供了便利的设定文字强调级别的类：
<p class="text-muted">Muted: This text is grayed out.</p> <p class="text-primary">Important: Please read the instructions carefully before proceed.</p> <p class="text-success">Success: Your message has been sent successfully.</p> <p class="text-info">Note: You must agree with the terms and conditions to complete the sign up process.</p> <p class="text-warning">Warning: There was a problem with your network connection.</p> <p class="text-danger">Error: An error has been occurred while submitting your data.</p>
对引用内容也做了修饰：
<blockquote class="pull-right"> <p>The world is a dangerous place to live; not because of the people who are evil, but because of the people who don't do anything about it.</p> <small>by <cite>Albert Einstein</cite></small> </blockquote>
其中的类是为了右对齐引用。
