Main Article: Building Character Sheets

This is an example for selecting attributes to be included in a Sheet Roll.

The key components are:

  • Update display of toggle buttons based on the associated flag, using Styling Checkboxes and Radios
  • Attribute name, button name, flag attribute name, and translation key all share the same base value.
  • Displaying the selected attributes (based on translation key)
  • Selected attribute list and dice pool value are stored in hidden input fields.
  • Roll button references the dice pool attribute with Auto-Calculating Values

HTML

<h1>Sheet Roller</h1>
<div class="roller">
  <textarea name="attr_dice_pool_display" tabindex="-1"></textarea>
  <div>
    <input type="text" name="attr_dice_pool" tab-index="-1"></input>
    <button type="roll" value="/roll @{dice_pool}d10"></button>
  </div>
</div>

<h1>Attributes</h1>
<div class="attributes">

CSS

/* Indicate that the toggle is active */
input.sheet-flag[value="1"] ~ button.sheet-toggle {
  border-color: blue;
