# Template

The `<template>` tag needs to be added within `<pageTemplates>` directly below the root tag. Each template needs to have an id to refer to it later. Content within a template is rendered with exact positioning (HTML speak: absolute position).

## Example

```markup
<adx>
  <pageTemplates>
    <template
      id="simple_header"
      pageSize="A4"
      pageMargins="10cm 2cm 5cm 2cm"
    >
        <text
          bottom="287mm"
          left="20mm"
          width="190mm"
          height="10mm"
          color="white"
          fontSize="80"
        >
            Header
        </text>
    </template>
  </pageTemplates>
  <body template="simple_header">
  ...
  </body>
</adx>
```

## Attributes

#### `id`

The unique identifier of the template. Referenced via the `template` or `firstPageTemplate` attribute on `<body>`.

#### `pageSize` (optional)

The page size as two lengths separated by a space (width height), e.g. `"210mm 297mm"`. The shorthand `"A4"` is equivalent to `"210mm 297mm"`. Defaults to `"210mm 297mm"` (A4).

#### `pageMargins` (optional)

Four lengths separated by spaces, in TRouBLe order (Top Right Bottom Left), e.g. `"10cm 2cm 5cm 2cm"`. Defaults to `"2cm 2cm 2cm 2cm"`.

## Allowed Children

A `<template>` can contain the following elements (rendered with absolute positioning):

* `<rect>`
* `<line>`
* `<text>`
* `<h1>`, `<h2>`
* `<image>`
* `<pageNumber>`
* `<qrCode>`
* `<hrCode>`
