Inline Tags

Inline tags let you apply formatting, embed media, and insert interactive fields. They use square bracket syntax with opening and closing pairs.

Where inline tags work

Every inline tag — typography, text properties, layout, media, form fields, and actions — renders inside any text element:

• Paragraphs (p)
• Headings (h1, h2, h3, h4, h5)
• Table headers and cells (th, td)
• List items (li)
• Columns layout cells

The same syntax works everywhere. No container or wrapper needed.

Syntax

[tag]content[/tag]
[tag, param1, param2]

Tags can be nested and combined freely. The engine processes them left-to-right, maintaining a stack for each formatting property.

Tag categories

Typography

Control font weight, style, and decoration within a text span.

Tag	Short	Description
[bold]...[/bold]	[b]...[/b]	Bold text
[italic]...[/italic]	[i]...[/i]	Italic text
[bolditalic]...[/bolditalic]	[bi]...[/bi]	Bold italic text
[underline]...[/underline]	[u]...[/u]	Underlined text
[strike]...[/strike]	[s]...[/s]	Strikethrough text
[caps]...[/caps]	—	UPPERCASE text (presentation only — source stays mixed-case)
[font, Name]...[/font]	—	Switch to a registered font family

HTML semantic aliases

Familiar HTML inline-element names route to the canonical tags above — useful when porting content from HTML or when the semantic name reads more naturally in template code:

Alias	Routes to	Meaning
[em]...[/em]	[i]	Emphasis (italic)
[strong]...[/strong]	[b]	Strong emphasis (bold)
[cite]...[/cite]	[i]	Citation (italic)
[ins]...[/ins]	[u]	Inserted text (underline)
[del]...[/del]	[s]	Deleted text (strikethrough)
[mark]...[/mark]	[hl, #FFFF00]	Default-yellow highlight

Text properties

Override font size, color, alignment, and position.

Tag	Short	Description
[fontsize, N]...[/fontsize]	[size, N]...[/size]	Set font size to N points
[fontcolor, color]...[/fontcolor]	[color, color]...[/color]	Set text color (hex or CSS3 name)
[letterspacing, N]...[/letterspacing]	[ls, N]...[/ls]	Track characters out (or in, with negative N) by N points
[highlight, color]...[/highlight]	[hl, color]...[/hl]	Background highlight on the span
[align, V]...[/align]	—	Override text alignment (l, r, c, j)
[superscript]...[/superscript]	[sup]...[/sup]	Superscript (raised text)
[subscript]...[/subscript]	[sub]...[/sub]	Subscript (lowered text)

Layout

Control spacing and positioning within a paragraph.

Tag	Description
[linebreak] or [br]	Line break (optional count: [br, 3])
[tab, X, Y]	Tab stop at X points from left, Y vertical offset

Media

Embed images and barcodes inline with text.

Tag	Short	Description
[image, path, W|H]	[img, path, W|H]	Inline image
[barcode, type, code, W|H]	—	Inline barcode

Form fields

Insert interactive AcroForm fields inline.

Tag	Description
[textfield, name, 'value', W|H]	Text input field
[textarea, name, 'value', W|H]	Multi-line text area
[checkbox, name, checked, W|H]	Checkbox
[radio, name, group, selected, W|H]	Radio button
[choicefield, name, opt1|opt2|opt3, index, W|H]	Dropdown select
[listbox, name, opt1|opt2, 'value', multi, W|H]	List box

Links

Attach a clickable target to a text span. Renders into PDF output.

Tag	Description
[link, URL]...[/link]	Clickable hyperlink
[goto, dest]...[/goto]	Jump to a named destination inside the document

Nesting

Tags can be nested to combine effects:

{ "p": "[b][fontcolor, #CC0000]URGENT:[/fontcolor][/b] Review [i]before[/i] [u]end of day[/u]." }

This renders: URGENT: (bold red) Review before (italic) end of day (underlined).

Where inline tags work

Inline tags are supported in any text element:

• Paragraph text (p)
• Headings (h1 through h5)
• Table header cells (th)
• Table data cells (td)
