1. Boostrap divides the desktop into a table of 12 rows * n columns for layout. This is the core of boostrap.
2. .row performs row-level division and must be included under .container.
3. col-xx-* performs column-level division, as shown below
<div class="container">
<div class="row">
<div class="col-md-3">1</div>
<div class="col-md-3">2</div>
<div class="col-md-3">3</div>
<div class="col-md-3">4</div>
</div>
<div class="row">
<div class="col-md-3">5</div>
<div class="col-md-3">6</div>
<div class="col-md-3">7</div>
<div class="col-md-3">8</div>
</div>
</div>4. Column offset, is achieved through col-xx-offset-*
<div class="container">
<div class="row">
<div class="col-md-3">1</div>
<div class="col-md-3">2</div>
<div class="col-md-3">3</div>
<div class="col-md-3">4</div>
</div>
<div class="row">
<div class="col-md-3">5</div>
<div class="col-md-3">6</div>
<div class="col-md-3 col-md-offset-3">7</div>
</div>
</div>5. Column sorting, can achieve left or right sorting of columns through .col-xx-push-* and .col-xx-pull-*
<div class="container">
<div class="row">
<div class="col-md-3">1</div>
<div class="col-md-3">2</div>
<div class="col-md-3 col-md-push-3">3</div>
</div>
<div class="row">
<div class="col-md-3">5</div>
<div class="col-md-3">6</div>
<div class="col-md-3 col-md-pull-2">7</div>
</div>
</div>
6. Column nesting , row can be nested in col.
<div class="row">
<div class="col-md-3">1</div>
<div class="col-md-3">2</div>
<div class="col-md-3">3</div>
<div class="col-md-3">
<div class="row">
<div class="col-md-1">5</div>
<div class="col-md-1">6</div>
<div class="col-md-1">7</div>
