Patterns For Presenting Data

Tables

Table tags: table, tr, td

<table>
<tr>
  <td class="t-Report-cell" #ALIGNMENT# headers="#COLUMN_HEADER_NAME#">
    #COLUMN_VALUE#
  </td>
</tr>
</table>

Lists

List tags: ul, li

List Structure

<ul>
  <li>Orange Juice <i class="fa fa-check-square-o"></i></li>
  <li>Milk <i class="fa fa-check-square-o"></i></li>
  <li>Eggs <i class="fa fa-square-o"></i></li>
  <li>Bread <i class="fa fa-square-o"></i></li>
  <li>Cornflakes <i class="fa fa-square-o"></i></li>
</ul>
