Main Article: Building Character Sheets

This is a general guide to different approaches/methods you can use to create the general layout of your custom character sheets.

Layout Types

Roll20 columns/rows

Good for basic layouts, but if you aim for a more complex layout/design, CSS Grid and CSS Flexbox is recommended.

Roll20 provides a few basic classes you can use to organize things into a simple column-based layout. To use them, just create a div with a class of '3colrow', '2colrow', or 'row'. Then inside of that div, create a div for each column with a class of 'col'. For example, to create a 3-column layout, you would could:

<div class='3colrow'>
  <div class='col'>
    <!-- Put the content for the first column here -->
  </div>

  <div class='col'>
    <!-- Second column -->
  </div>

  <div class='col'>
    <!-- Third column -->
  </div>
</div>

HTML Table

HTML table guide Many older sheet use HTML tables for layout, but it's harder to customize and adjust to looks of it compared to other methods, so it's generally not seen as a good idea for sheet layout. Roll20 don't accept new sheet submissions that rely on HTML tables for design, so this option shouldn't be used if you want your sheet published. Old sheet using tables do exist int the Roll20 character sheet repository, but they shouldn't be used as templates for your own designs.

Pages

Example: Tabs

When trying to mimic the paper-version of the sheet, or the sheet starts to become too long, it's a good idea to split up content into separate tabs/pages, see Tabs.

The section above also show how you can hide areas with checkboxes, useful for temporally hiding/expanding some section for displaying more info.
