{
"$schema": "https://schemas.wp.org/trunk/theme.json",
"model": 2,
"settings": {},
"types": {},

}
Right here’s a simplified breakdown:
Schema
This section is in truth non-compulsory to have in block subject matters, so you could or would possibly not see it in yours.
The schema assets hyperlinks the URL to the WordPress JSON schema, which defines the worldwide settings, types, and different configurations to your theme.

This phase specifies which API model of the theme.json layout is being utilized by the document and guarantees it follows the proper construction.
As of the writing of this text, the API is at model 2.

"palette": [
{
"slug": "base",
"color": "#ffffff",
"name": "White"
},
{
"slug": "contrast",
"color": "#222222",
"name": "Dark"
},
{
"slug": "accent",
"color": "#f08080",
"name": "Pink"
},
{
"slug": "accent-2",
"color": "#90ee90",
"name": "Light Green"

"slug": "times-new-roman",
"name": "Times New Roman"
}
],

}
}
Should you take a look at the code, the language used is lovely simple to grasp. You’ll inform that the settings are defining the colours, font households, font sizes, and spacing used within the theme.
If there are any references right here or on your theme that you just don’t perceive, you’ll take a look at the authentic WordPress Settings Reference.
Some components, like colours and font households, have slugs, like this:
{
"settings": {
"colour": {
"palette": [
{
"slug": "base",
"color": "#ffffff",
"name": "White"
},
These will come in handy for the styles section later on to make presets, which we will explain in the next part.
Styles
While the settings section defines the theme’s default customization options, the styles section applies them to the theme.
Here, you can apply the customization settings to the entire website or at a block level using presets.
Let’s check out the example below:
{
"settings": {
// Existing settings from the previous example
},
"styles": {
"color": {
"background": "var(--wp--preset--color--base)",
"text": "var(--wp--preset--color--contrast)"
},
"elements": {
"link": {
"color": {
"text": "var(--wp--preset--color--accent-2)"
}
},
"h1": {
"fontSize": "var(--wp--preset--font-size--xx-large)",
"lineHeight": "1.2",
"marginBottom": "1rem"
},
"h2": {
"fontSize": "var(--wp--preset--font-size--x-large)",
"lineHeight": "1.2",
"marginBottom": "1rem"
},
"h3": {
"fontSize": "var(--wp--preset--font-size--large)",
"lineHeight": "1.2",
"marginBottom": "1rem"
}
}
}
}
As you can tell, there is this line of code appearing throughout this snippet: var(--wp--preset--xxx) . These are presets, which are shortcuts in the styles section that refer back to the values defined in the settings section.
For example, consider {"slug": "base", "color": "#ffffff", "name": "White"} in the settings section. Here, "base" is the slug, and the corresponding preset for this color is var(--wp--preset--color--base) .
Therefore, the code "color": {"background": "var(--wp--preset--color--base)" in styles says that the background color of this theme is white.
Custom Templates
Block theme developers can create predefined layouts for custom pages, posts, or post types for users to use.
For example, the Twenty Twenty-Four theme has several custom templates defined in the theme.json file: Page No Title, Page With Sidebar, Page with wide Image, and Single with Sidebar.
You can use any of these to create your content.
],
"customTemplates": [
{
"name": "page-no-title",
"postTypes": ["page"],
"identify": "Web page No Identify"
},
{
"call": "page-with-sidebar",
"postTypes": ["page"],
"identify": "Web page With Sidebar"
},
{
"call": "page-wide",
"postTypes": ["page"],
"identify": "Web page with huge Symbol"
},
{
"call": "single-with-sidebar",
"postTypes": ["post"],
"identify": "Unmarried with Sidebar"
}
]
Something to notice is that the theme.json document best references the templates by means of call and gives metadata about them, reminiscent of their identify and the put up sorts they’re meant for.
On the other hand, the true look and capability of the customized templates are outlined in separate template recordsdata within the theme folder.
To look them, you’ll pass to public_html » wp-content » subject matters » your-theme-name » templates.
Template Portions
Template portions are reusable spaces you’ll observe throughout your customized templates. Those are components like headers, footers, sidebars, and so forth.
Right here’s what the ones template portions seem like registered in theme.json:
"templateParts": [
{
"area": "header",
"name": "header",
"title": "Header"
},
{
"area": "footer",
"name": "footer",
"title": "Footer"
},
{
"area": "sidebar", // Removed "uncategorized"
"name": "sidebar",
"title": "Sidebar"
},
{
"area": "post-meta", // Removed "uncategorized"
"name": "post-meta",
"title": "Post Meta"
}
]
Like customized templates, the theme.json document best references the templates.
Their exact look is outlined in their very own template section recordsdata within the portions folder.
Patterns
Patterns are pre-made collections of blocks that help you create customized content material layouts for your pages, posts, or anyplace else on your theme.
While you open the complete web site editor, you could realize the Patterns menu. That is the place you’ll to find all of the to be had patterns to your Gutenberg block theme.
With theme.json, theme builders can reference patterns from the general public Trend listing. It’s a good way to provide extra customization choices with out designing those reusable blocks your self.
For instance, the Twenty Twenty-4 theme references two patterns from the authentic listing: 3 columns of products and services and shoppers phase:
"patterns": [
"three-columns-of-services",
"clients-section"
]
We all know this as a result of those patterns are within the Patterns menu within the complete web site editor.
On the other hand, they’re now not within the patterns folder within the theme listing.
Observe: Chances are you’ll realize that the templates, portions, and patterns folders on your theme listing include recordsdata now not laid out in theme.json, however they’re nonetheless visual within the complete web site editor.
Should you’re curious, it’s because WordPress is designed to routinely acknowledge and use those folders in response to their naming conventions and site inside the theme’s listing.
