[edit] Layout Methods

Here are some of the popular approaches/frameworks that people use for designing HTML/CSS layouts, with examples on Roll20 character sheets.

See #Sheet Templates for more comprehensive examples of sheets using these methods.

Check CSS Layout cookbook

[edit] CSS Grid

Many newer character sheet use CSS Grid for their layout, and is the recommended method doing the general layout of sections on a sheet. Aligning things in a grid, by using rows & columns is great, and you can have elements overlap and even span several "spots" on the grid. Many tend to use flexbox for styling inside individual sections/blocks on the sheet, if grid seems overkill.

Example:

<div class="sheet-grid-section">
  <span>1st span</span>
  <span>2nd</span>
  <span>3rd</span>
  <span>4th, stuff</span>
  <span>5th, other</span>
  <span>6th</span>
</div>

.charsheet .sheet-grid-section{
  display: grid;
  grid-template-columns: 600px 300px;
  grid-template-rows: 150px 150px 150px;
}

[edit] grid-template-areas

grid-template-areas can be used for naming sheet sections and then easily display in a human-readable way how each section is positioned in the grid. The drawback is that you can't have sections that overlap with each-other using this.

<div class="sheet-grid-section">
  <div class="sheet-namelvl sheet-block">
    <label>Name</label>
  </div>
  <div class="sheet-hp sheet-block">
    <span>HP</span>
  </div>
  <div class="sheet-stat sheet-block">
    <h3>Main Stat</h3>
  </div>
  <div class="sheet-skills sheet-block">
    <h3>Skills</h3>
    <label><button name="roll_str" value="/r 1d6+@{str}" type="roll"></button> strength <input type="number" name="attr_str"></label>
    <label><button name="roll_agi" value="/r 1d6+@{agi}" type="roll"></button> agility <input type="number" name="attr_agi"></label>
    <label><button name="roll_mind" value="/r 1d6+@{mind}" type="roll"></button> mind <input type="number" name="attr_mind"></label>
  </div>
  <div class="sheet-equip sheet-block">
    <h3>Equipment</h3>
  </div>
  <div class="sheet-notes sheet-block">
    <h3>Notes</h3>
  </div>
</div>

Simple sheet layout using grid-template-areas

.charsheet .sheet-grid-section{
  display: grid;
  grid-template-columns: 400px 200px;
  grid-template-rows:  60px 150px 150px 150px;
  grid-template-areas:"namelvl hp     "
                      "skills  stat   "
                      "skills  equip  "
                      "notes   equip  ";
  grid-gap: 5px;
}
.charsheet div.sheet-block{
  display: grid;
  justify-content: center;
  padding: 5px;
  border: 3px solid black;
}
.charsheet div.sheet-namelvl{
  grid-area: namelvl;
}
.charsheet div.sheet-hp{
  grid-area: hp;
}
.charsheet div.sheet-stat{
  grid-area: stat;
}
.charsheet div.sheet-skills{
  grid-area: skills;
}
.charsheet div.sheet-equip{
  grid-area: equip;
}
.charsheet div.sheet-notes{
  grid-area: notes;
}

[edit] Subgrid

Subgrid is only available for Firefox, but when it's released for Chrome sheet design will get more easy as you can use the main grid lines in children, making it easier to align sub-components with main components of the sheet.

You can implement subgrid in sheets, and then create a fallback design, in case the browser doesn't support CSS Subgrid.

<div class="sheet-grid">
  <div class="sheet-item">
    <div class="sheet-subitem"></div>
  </div>
</div>

.charsheet .sheet-grid {
  display: grid;
  grid-template-columns: repeat(9, 1fr);
  grid-template-rows: repeat(4, minmax(100px, auto));
}

.charsheet .sheet-item {
  display: grid;
  grid-column: 2 / 7;
  grid-row: 2 / 4;
  grid-template-columns: subgrid;
  grid-template-rows: repeat(3, 80px);
}

.charsheet .sheet-subitem {
  grid-column: 3 / 6;
  grid-row: 1 / 3;
}

[edit] CSS Flexbox

CSS Flexbox guide

Flexbox is a good way to align elements in rows or columns that flex and wraps around to new rows depending on the elements. Better than using the old float: right; method of aligning things. Some sheet authors use CSS Grid for bigger elements and gid-like sections of a sheet, while using Flexbox for smaller components in the sheet.

Flexbox Froggy is a great training game for learning about Flexbox.

flexbox.help

<div class="sheet-flex-section">
  <span>1st</span>
  <span>2nd</span>
  <span>3rd</span>
  <span>4th</span>
  <span>5th</span>
  <span>6th</span>
</div>

.charsheet .sheet-flex-section{
  display: flex;
  flex-direction: column;
  flex-wrap: wrap;
  align-items: center;
}

[edit] Multiple-column layout

See more at: Multiple-column layout

<div class="sheet-container">
  <span>1st</span>
  <span>2nd</span>
  <span>3rd</span>
</div>

.charsheet .sheet-container {
  column-count: 3;
}

[edit] Roll20 columns/rows

Okay for basic layouts, but if you aim for a more complex/sophisticated layout/design, CSS Grid and/or 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 classnames such as sheet-3colrow, sheet-2colrow, or sheet-row. Then inside of that div, create a div for each column with a class of sheet-col. For example, to create a 3-column layout:

<div class="sheet-3colrow">
  <div class="sheet-col">
    <h2>Skills</h2>
    <label>str</label>
    <input type="number" name="attr_str">
    <label>agi</label>
    <input type="number" name="attr_agi">
    <label>mind</label>
    <input type="number" name="attr_mind">
  </div>

  <div class="sheet-col">
    <h2>Main Stats</h2>
    <label>hp</label>
    <input type="number" name="attr_hp">
    <label>defence</label>
    <input type="number" name="attr_defence">
  </div>

  <div class="sheet-col">
    <h2>Equipment</h2>
    <textarea name="attr_equip"></textarea>
  </div>
</div>

You can then further style & adjust then in the CSS:

.charsheet .sheet-col{
  background: grey;
}

The it's not clear what the css for these are, so styling gets harder the more changes you try to make on how they look. It's better to switch to use Flexbox/CSS Grid eventually.

You can use browser tools to inspect and figure out how the css for these columns & rows work.

[edit] HTML Table

Using <table> is the fourth, and least recommended method, for designing basic sheet layout.

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.

HTML table guide
Tables - MDN Web docs
Article: Why you shouldn't use HTML tables for layout

Older sheets using tables do exist in the Roll20 character sheet repository, but they where created before the rule was set in place. These older sheets shouldn't be used as templates for your own designs, instead pick more recently created sheets, or some suggested here.

[edit] Sheet Components

sheet with multiple pages/tabs

[edit] 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.

[edit] Images

Main Page: Image use in character sheets

You'll likely want to use images to improve the looks of a sheet, and there are a few example of how to do so, like displaying a logo or having a nice background.

This might even include showing the characters Avatar or Token on the sheet.

[edit] Repeating Sections

If you use repeating sections on your sheet, styling and planing how your design them can have a large impact on sheet layout, requiring a flexible design if users want lots of entries.

[edit] Sheet Templates

There exist a couple of character sheet templates that are intended as a starting point for character sheet creations.

Complete Sheet Examples - list of current sheets that can be good examples in general
Roll20's "kitchensink" - Roll20's template, uses the built-in Roll20 columns/rows for layout (fairly old and dated example, but functional)
CSS Grid sheet template - simple sheet layout using CSS Grid, by Andreas J.
Cassie's sheet template - sheet skeleton that uses PUG & SCSS, not recommended for beginners - by Cassie
Blades-template - by Jakob - based on Blades in the Dark-sheet
