How to change the space below the title?

Good day, everyone.

I’m learning how to make a template on Typst, but for some reason I can’t change the space below the #title() inside the template function. However, when I place the same code outside the #let it works. It seems to be specifically the set block function, as the set text renders normally.

 // -- Configure title --
// This one doesn't work
  show title: set block(
    below: line-height * 20
  )
  
  // This one does
  show title: set text(
    size: font-size + 3pt,
    weight: "regular"
  )

Can someone help me?

Full code 
#let dull(
  // -- Metadata --
  title: none,
  subtitle: none,
  author: none,
  date: none,
  // -- Document --
  paper-size: "a4",
  language: "pt",
  // -- Font --
  body-font: "Tex Gyre Termes",
  raw-font: "JetBrains Mono",
  font-size: 11pt,
  leading-ratio: 1.75,
  // -- Colors --
  background-color: rgb("#ffffff"),
  foreground-color: rgb("000000"),
  // -- Body --
  body,
) = {
  // -- Type scale --
  let title-size = font-size + 3pt
  let heading-size = font-size + 2pt
  let subheading-size = font-size + 1pt
  
  // ── Baseline grid --
  let line-height = font-size * leading-ratio
  
  // -- Spatial system --
  let margin-vertical = line-height * 4
  let margin-horizontal = line-height * 7
  
  // ── Configure metadata --
  set document(title: title, date: date)
  if author != none {
    set document(author: author)
  }
  
  // -- Configure text --
  set text(
    font: body-font,
    size: font-size,
    fill: foreground-color,
    ligatures: true,
    discretionary-ligatures: true,
    lang: language
  )
  show raw: set text(font: raw-font)
  
  // -- Configure paragraph --
  set par(
    leading: line-height - font-size,
    spacing: line-height,
    justify: true,
    justification-limits: (
      spacing: (
        min: 100% * 2 / 3,
        max: 100% * 3 / 2,
      ),
      tracking: (
        min: -0.01em,
        max: 0.01em,
      ),
    ),
  )
  
  // -- Configure page --
  set page(
    paper: paper-size,
    fill: background-color,
    margin: (
      x: margin-horizontal,
      y: margin-vertical
    )
  )
  
  // -- Configure title --
  show title: set block(
    below: line-height * 20
  )
  
  show title: set text(
    size: font-size + 3pt,
    weight: "regular"
  )
  
  // -- Configure headings --
  show heading: set text(
  font: body-font,
  weight: "regular",
  fill: foreground-color
  )
  
  show heading: set block(
    above: line-height * 4/3,
    below: line-height * 1/2
  )
  
  show heading.where(level: 1): set text(
      size: heading-size
  )
  
  show heading.where(level: 2): set text(
      size: subheading-size
  )
  
  show heading.where(level: 3): set text(
      size: font-size,
      weight: "bold"
  )
  
  // -- Body --
  body
}

#show: dull.with(
  title: "This is a test",
  author: "Paprika"
) 

#title()

#lorem(50)

#lorem(75)

= Título 1
#lorem(50)

== Título 2
#lorem(50)

=== Título 3
#lorem(50)

Hi @Batch, this one is fun :).

You named your title title and so you shadow the built-in Typst title function inside your template function.
Show rules also accept text, so the two show title: ... calls look like this:

// Doesn't work, because text isn't a block element 
show "This is a test": set block(
  below: line-height * 20
)
  
// Works, because text has text properties
show "This is a test": set text(
  size: font-size + 3pt,
  weight: "regular"
)

You can either rename your title parameter or use the std module to access the built-in title with:

show std.title: set block(
  below: line-height * 20
)
  
show std.title: set text(
  size: font-size + 3pt,
  weight: "regular"
)

Edit: Thanks for providing the working example code!
