The standard location for the theme.json record is inside of wp-content/topics/[your-theme]. If the record isn’t there, you will have to open your favourite coding editor and create the record as essential. Don’t fear concerning the contents for now — we’ll get to that in a while.

What you wish to have to paintings with theme.json
After all, no longer everybody will be capable of open up the config record and get to paintings. You’ll nonetheless want some elementary talents and information to construct and customise a theme:
- Fundamental JSON wisdom. We expect it’s one thing you’ll select up rapid, however nonetheless, familiarity with JSON syntax and construction is an important.
- Figuring out of CSS. You’ll to find that many
theme.jsongadgets and homes correspond to its CSS opposite numbers. CSS ‘chops’ will likely be a get advantages right here. - WordPress Block Editor wisdom. Figuring out how Blocks paintings, along side their customization choices, will will let you as you construct.

Taking a look on the anatomy, construction, and hierarchy of theme.json
The theme.json record will clearly have a construction in position that you wish to have to know. It additionally has a hierarchy, along side some distinctive parts that want additional rationalization.
That is most probably probably the most advanced a part of the use of the configuration record, however even then, you’ll seize the ideas simply.
Let’s get started with construction, then transfer directly to the opposite parts of theme.json.
Fundamental construction
For the reason that the record follows the JSON layout, you could already perceive the overall thought of the construction. To begin with, all of the record object wraps in curly braces, as will probably the most quite a lot of different gadgets inside of. Every object is composed of key-value pairs, use unmarried or double quotes for keys, and commas to finish the road.
The naked minimal a theme.json record wishes are model, settings, and kinds gadgets:
{
"model": 2,
"settings": {
// World settings move right here
},
"kinds": {
// World kinds move right here
}
}The settings and kinds gadgets are easy, however model calls for extra rationalization. This price will likely be an integer that fits the API model you employ to learn your record. The present API model is 3, even though model 2 could also be not unusual, and you’ll migrate from older variations.
Maximum theme.json record buildings will even come with a schema. In a nutshell, this allows you to paintings with auto-completion inside of code editors and gives validation for the record. You’ll upload this on the peak of the record:
{
"$schema": "https://schemas.wp.org/trunk/theme.json",
"model": 2,
"settings": {
},
"kinds": {
}
}From right here, you’ll upload quite a lot of homes and gadgets to settings and kinds to construct upon your record.
Hierarchy
The theme.json record follows a hierarchical construction and is just one point of the whole hierarchy for settings and kinds in your web site. When you’ve got CSS wisdom, working out this will likely be more straightforward for you, as this record is an identical in complexity to CSS.
Briefly, the customizations you are making to theme.json won’t all the time display at the entrance finish of your web site. Person configurations take precedence over the whole lot. This implies no matter adjustments happen at the Look > Editor display screen inside of WordPress will display up at the entrance finish:
When you use a kid theme and come with a theme.json record, this may occasionally override each and every exchange rather than the ones made with the Web site Editor. Likewise, anything else you outline throughout the dad or mum theme’s configuration record will override WordPress’ default settings and kinds. It’s this record we’re that specialize in inside of this submit, even though WordPress has its personal theme.json record, too.
Whilst it gained’t catch the attention of this submit, you’ll additionally override values the use of hooks and filters. Those dynamic filters can help you create plugins and topics that still exchange theme and platform settings and kinds.
Block grammar
When you head into the WordPress Block or Web site Editor, open a submit or web page, and toggle the Code Editor, you’ll realize quite a lot of what seems like HTML feedback throughout the content material:
It is because as an alternative of the use of PHP recordsdata, Block Topics use HTML recordsdata along side feedback and Block markup to create your web site. The mix of those parts ends up in the ‘Block grammar’ you wish to have to jot down your theme.json record.
For Blocks that include content material, such because the Paragraph Block, you wrap that content material:
Content material is going right here!
In different circumstances, you’ll best want single-line feedback or those who self-close. With some Blocks, you’ll mix varieties to create your layouts and designs. You’re in a position to nest those feedback, too:
Right here, we create a Columns Block the use of a wrapper remark. Inside of, we will start to upload HTML to design the ones columns and come with particular person column wrappers. This could be trivial at the entrance finish, as you’ll frequently position Blocks within of one another.
To seek out the markup for a specific Block, you want to select across the Block Editor Guide till you to find what you wish to have. One of the best ways, regardless that, is just so as to add the Block to WordPress, open the Code Editor, and duplicate the markup from there.
In the case of adjustments you’ll make inside of that markup, we’ll quilt that during a later phase.
How theme.json and WordPress complete web site enhancing mix
From the dialogue on hierarchy, you’ll remember that theme.json is a huge a part of FSE. Each paintings in combination to come up with a complete theming answer for WordPress. As an example, the World Types interface is largely the visible illustration of your theme.json settings.
You’ll be able to adjust settings both within the World Types panel or the configuration record, and WordPress will replace the corresponding values as essential. Whilst the Web site Editor settings will take priority, theme.json will act as the basis to your theme’s personal kinds. For the top consumer, World Types allows them to change your defaults with their very own customizations with out the will for code or to edit the theme.json record.
What’s extra, the CSS tradition homes you outline in theme.json turn out to be to be had within the World Types interface. This shall we customers leverage those homes for extra constant styling throughout a web site. This extends to with the ability to outline particular Block kinds and settings too, which you’ll tweak farther from the WordPress dashboard.
In a nutshell, theme.json supplies extra granular regulate over settings, kinds, and extra. It’s a developer-level instrument that provides a easier and streamlined enjoy than vintage approaches. By contrast, the World Types interface offers everybody the danger to customise a theme to their very own liking. As you increase topics additional, you’ll see how each paintings in tandem to assist create web site designs and layouts.
Running with the theme.json record homes
With an working out of the fundamentals, you’ll start to paintings with the gadgets and homes inside of theme.json. We gained’t be capable of quilt each and every use case or eventuality. Then again, by way of the top of this educational, you’ll be capable of construct topics that supply complete capability and glance nice at the entrance finish.
Settings
The settings belongings means that you can regulate which options you be offering within the Web site Editor and the way they behave. It’s a top-level belongings, and also you’ll in most cases to find a couple of ranges of nesting.
After we take a look at kinds and their permutations, you’ll see that there’s some crossover between those choices, however each varieties have a job in developing your theme.
You have got a choose selection of homes to be had:
{
"model": 3,
"settings": {
"appearanceTools": false,
"blocks": {},
"border": {},
"shade": {},
"tradition": {},
"dimensions": {},
"structure": {},
"place": {},
"shadow": {},
"spacing": {},
"typography": {},
"useRootPaddingAwareAlignments": false
}
}The reputable WordPress Theme Developer Guide features a reference for all of those settings (and kinds). Then again, right here’s a snappy assessment of a couple of vital ones that want additional rationalization:
appearanceTools. This catch-all belongings permits quite a few others and is supposed as a time-saver. It’s going to set border choices, typography line-heights, padding, margins, and a lot more.blocks. Whilst maximum of your paintings will take a look at international settings and kinds, theblocksbelongings means that you can do that on a per-Block foundation. The idea that isn’t one thing we quilt in additional element right here, however the Theme Developer Guide has very good documentation in this aspect oftheme.json.tradition. This distinctive belongings has no capability in that you make a decision what it does. You’ll use it to create tradition CSS homes to your theme, and the scope you have got on be offering is huge.useRootPaddingAwareAlignments. Once more, this can be a advanced belongings that we gained’t quilt in complete. It necessarily is helping you put your theme’s horizontal padding kinds and springs with numerous energy. You’d use it the place you need to let full-width pieces stretch to the perimeters of the display screen whilst the use of padding at the root part.
Be aware that you just don’t wish to upload any homes to theme.json you don’t wish to paintings with. As an example, when you don’t need to paintings with appearanceTools, you’ll merely go away it out relatively than outline it with false.
The way to outline settings inside of theme.json
In the case of defining settings, every belongings has quite a few sub-properties of key-value pairs. As an example, you’ll create shade palettes on this means:
{
"model": 3,
"settings": {
"shade": {
"palette": [
{
"color": "#0073aa",
"name": "Primary",
"slug": "primary"
},
{
"color": "#23282d",
"name": "Secondary",
"slug": "secondary"
}
],
…Different homes have easy Boolean values, which is able to toggle the ones options on or off throughout the Web site Editor:
{
"model": 3,
"settings": {
"shade": {
"background": true,
"defaultPalette": true,
"hyperlink": true,
"textual content": true
}
}
}While you outline your settings, you’ll introduce styling for them. Let’s read about this now.
Types and magnificence permutations
Whilst settings defines get right of entry to to positive styling choices, the kinds belongings lets you outline the ones international kinds to your theme. Once more, this is a top-level belongings that may use a couple of ranges of nesting. You’re in a position to focus on particular parts, Blocks, and even use tradition CSS homes.
It’s vital to outline theme kinds right here so you’ll get right of entry to and customise them from the Web site Editor. You’re in a position to paintings with a selection of parts:
{
"model": 3,
"kinds": {
"border": {},
"shade": {},
"dimensions": {},
"clear out": {},
"shadow": {},
"spacing": {},
"typography": {},
"css": {}
}
}Then again, you gained’t frequently use many of those as secondary-level homes. As a substitute, some will principally paintings with Blocks or parts. For instance:
…
"kinds": {
"blocks": {
"core/staff": {
"shade": {
"textual content": "#000000",
"background": "#ffffff",
"hyperlink": "#777777"
}
…For international kinds, you’ll paintings at the root — which correlates to the tag of your web page. For particular parts, you’ll observe a an identical construction to Blocks, this time the use of the parts belongings:
…
"kinds": {
"parts": {
"button": {
"shade": {
"textual content": "#ffffff",
"background": "#aa3f33"
}
…When you take a look at any adjustments you are making throughout the Web site Editor, you will have to see them in position. The markup will even generate CSS for no matter kinds you create:
Be aware that you’ll additionally taste pseudo-classes for parts comparable to hover and center of attention kinds:
…
"parts": {
"button": {
"shade": {
"textual content": "#ffffff",
"background": "#aa3f33"
},
":hover": {
"shade": {
"background": "#822f27"
}
…Making use of kinds is much more in-depth than this, and that’s one of the most improbable positives about the use of theme.json.
Taste permutations
Sooner than we transfer on, you’ll wish to learn about taste permutations. You’ll be able to see those quite a lot of shade palettes and typography stylings throughout the FSE interface:
Then again, those aren’t one thing you code into theme.json. As a substitute, you’ll create selection variations of the record, give them a novel title, and retailer them inside of a theme’s kinds listing:
Be aware that the name throughout the markup is exclusive to every selection JSON record. Then again, it’s an not obligatory box — even though we suggest you employ it for readability and the most productive enjoy.
Customized templates and template portions
Just like taste permutations, theme.json means that you can sign in tradition templates and related template portions. To sign in the markup is easy:
"customTemplates": [
{
"name": "my-template",
"title": "My Template",
"postTypes": [
"page",
"post"
]
}
]The customTemplates belongings wishes you to outline 3 parts:
title. This will likely correspond to a template you create inside of your theme’s templates listing, comparable to /template/my-template.html.name. That is the human-readable model of the template’s title.postTypes. With out definition, this defaults to a web page, however you’ll specify an array of submit varieties that the template is acceptable for.
Customers will likely be in a position to make a choice any templates you sign in from throughout the Web site or Block Editor:
In the case of template portions, you don’t wish to sign in them, however we suggest it. The construction is very similar to registering templates:
…
"templateParts": [
{
"area": "header",
"name": "header",
"title": "Header"
},
…Here, the name and the title match the same definitions as full templates. The area relates to where the part belongs: the header, footer, or uncategorized are the defaults, but you can assign template parts to any custom area.
We encourage you to look into how to display these template parts, too, as they won’t show up without some extra coding. Even so, registering them is straightforward.
Patterns
To finish up, let’s discuss Block patterns. You’re able to bundle any number of these within your theme.json file using a top-level array. Any suitable pattern from the WordPress Pattern Library is available to include in your file:
Defining the array is simple: you use the patterns property and the slug of the associated pattern from the library URL:
With this slug, you can populate the patterns markup:
{
"version": 3,
"patterns": [
"fullwidth-vertically-aligned-headline-on-right-with-description-on-left"
]
}You’ll be in a position to make a choice them from throughout the Block Editor Development Listing:
This straightforward strategy to carry Development Library belongings into your topics is to hand and treasured. It’s but one more reason that the theme.json record is rapid turning into a favourite strategy to construct amongst WordPress theme builders.

"$schema": "https://schemas.wp.org/trunk/theme.json",
"model": 3,
"settings": {
"appearanceTools": true,
"shade": {
"palette": [
{
"name": "Primary",
"slug": "primary",
"color": "#0073aa"
},
{
"name": "Secondary",
"slug": "secondary",
"color": "#23282d"
}
]
},
"typography": {
"fluid": true,
"fontSizes": [
{
"length": "13px",
"slug": "small",
"title": "Small"
},
{
"length": "16px",
"slug": "customary",
"title": "Customary"
…Subsequent, you’ll glance to create tradition CSS homes the use of the slugs you outline. As an example, you’ll have created tradition font weights:
…
"tradition": {
"fontWeight": {
"gentle": 300,
"common": 400,
"medium": 500,
"formidable": 700
},
…While you end together with your settings, it’s time to specify kinds.
…
"kinds": {
"shade": {
"background": "var(--wp--preset--color--base)",
"textual content": "var(--wp--preset--color--main)"
},
…Customizing your Block kinds will come subsequent, and this might constitute an enormous portion of your theme.json record.
…
"kinds": {
"block": {
"core/separator": {
"shade": {
"textual content": "var(--wp--preset--color--main)"
},
"typography": {
"fontSize": "var(--wp--preset--font-size--large)"

"core/site-tagline": {
"spacing": {
"margin": {
"backside": "20px"
}
},
"typography": {
"fontSize": "var(--wp--preset--font-size--small)"
}
},
"core/site-title": {
"typography": {
"fontSize": "var(--wp--preset--font-size--medium)",
"fontWeight": "var(--wp--custom--font-weight--semi-bold)",
"lineHeight": "var(--wp--custom--line-height--none)"
},
…In spite of everything, you’ll wish to design any tradition templates and template portions and sign in them inside of theme.json. This could also be the time to sign in any Block patterns you need to make use of and create them if essential.
