Section specific Theme.json #40318
Comments
Happy to see this, theme.json not cascading like CSS has been weird! Cascade I’d like to propose adding font sizes as well to this (see e.g. #39277) Sectioned content Then came template parts, who seem to become the same thing, but do NOT play nice with the ‘main groups’. Will there be any plans to ‘set a group as section’? Or even a dedicated section block? I feel template parts and sections should ultimately be close to the same thing in terms of DOM output. Because they create highly sectioned and thematically (and in terms of content) similar areas that are interchangeable. |
Miguel and I started looking into this and prepared #40547 I've updated the issue description with a preliminary list of tasks. |
We aim to introduce a new source for settings (& partially to styles), in addition to what we already use, the Let's take a given setting, say By source algorithm (settings coming from block attributes first, settings coming from the block editor store later):
By context algorithm (settings for the block first, settings for the global later - disregarding what the source is):
For settings, the "by source" algorithm works best. This allows us to do things like this easily:
For "styles", it doesn't matter which algorithm we use because they don't cascade (the top-level styles are attached to the "section", they're not used to fill the block styles):
I think the "by source algorithm" is a better representation of what we want to achieve: that sections become the source of truth for configuring whatever is within. |
Another detail is: if the section is a group block and it has the following settings: {
"settings": {
"color": {
"link": true
},
"blocks": {
"core/group": {
"color": {
"link": false
}
}
}
}
} The link color should be disabled for any group that is a children of the section. But, given the section is a group itself, what its behavior should be? I think the link should be enabled. This is, the |
I was reading your conversation on #40547 (comment), but as that PR is already merged, I'll answer here 🙂 Have you considered going with the by context algorithm but adding the ability to change all blocks at once with @oandregal, in your example of #40547 (comment), instead of doing this to disable the typography settings of all the blocks (even the ones that have been explicitly configured) {
"settings": {
"typography": {
"customFontSize": false,
"dropCap": false,
"fontSizes": [],
"fontStyle": false,
"fontWeight": false,
"letterSpacing": false,
"lineHeight": false,
"textDecoration": false,
"textTransform": false
}
}
} you would do this: {
"settings": {
"blocks": {
"*": {
"typography": {
"customFontSize": false,
"dropCap": false,
"fontSizes": [],
"fontStyle": false,
"fontWeight": false,
"letterSpacing": false,
"lineHeight": false,
"textDecoration": false,
"textTransform": false
}
}
}
}
} That is saying, "I want to overwrite the explicit settings of all the blocks". That way, it's easy to overwrite both the global settings and the explicit block settings. |
Noting that this is also related to #27233. |

Summarising one of main the problems we're trying to solve here: When designing the sections of a page (or even entire pages/templates) you often want to vary outside the default element styling of your site (e.g. a dark section with light text). To do this currently you need to manually set background and text colour each and every time and there are gaps in what you can control within a section (e.g.buttons). This project aims to solve that pain point by allowing you to create sets of styles that can be applied to sections or even entire pages. Here's an initial exploration that combines rethinking the global styles IA with some previous explorations around colour sets. We're extending the idea of colour sets to all styles. element-variations.mp4Note that we'd include element selection within the page/template inspector as well so you can style entire pages. There are a couple of trade-offs that come with this work that would be worth discussing.

We have #53667 for 6.4 which offers a valuable starting point that might lead to colour/style sets seen above or element styling beyond colours. |
Moving this out of "done" as that's for fully completed work and #53667 is already listed there. Moving this to 6.5 instead. |
Which will be much more empowering imo — even if only theme.json to start with. |
A draft proof of concept for this feature for WP 6.5 is up in #56234. It is only intended as a first step towards covering both section-specific styling and element color sets. An earlier exploration looked at storing the section styles within the block instance's style attribute however it was suggested that it instead be stored within Global Styles to facilitate re-use. To limit the scope such that it is achievable for 6.5, #56234 is code-only except for a minimal UI to apply a section style to a block instance. Future follow-ups post 6.5 should include updating Global Styles to allow user-created section styles as well as the ability to push a block instance’s styles to Global Styles as a section style. |
@aaronrobertshaw Should we close this issue? Are there any other iterations planned for this? |
@youknowriad I think related to this is the ability to save these chunks as their own entries in |
I guess we have it in #53480. |
And this one as well #45371 |
Along with the issues linked already, #62686, would also factor into the ability to manage style objects.
This is the part of the issue I'm most unclear on and so am not 100% sure if it can be closed. The context here is that we had this along with things like colorways and typesets as separate yet partially overlapping concepts. I was never able to achieve a consensus on how we could unify them all. The end result was that Section Styles evolved into an extension of the Block Styles feature. That mechanism doesn't currently support theme.json settings within them, they're purely styles at this point. Separate to the block style variations though it is possible to add theme.json settings within a block's attributes. The catch is the two feature aren't integrated. If we're happy that Section Styles meets the primary goal of this issue, then I think this can be closed out. We can create fresh, focused, issues for required enhancements like custom settings (e.g. palettes) within block style variations. Those can then take into account more recent developments, like support for theme.json partials defining block style variations, what comes of #62686 etc. TL;DR I'm not 100% sure due to Section Styles not supporting settings yet but if pushed I'd lean towards closing this one out and creating something fresh and clear given the current situation. |
What would it take for sections styles to support settings? |
That's a good question! Given the experience of implementing the first iteration of section styles, I'm sure there'll be plenty of edge cases and a few blockers to work around. So first of all, it might take some time. The most immediate question for me is whether this should be done before Global Styles & Theme.json: Next Steps reaches its conclusion or not. If we're completely reworking how we'll use the global styles post type, that might provide a lot of freedom and power to clean up the data around theme.json and/or block style variations. If we proceed on supporting settings for block style variations now, it's one more thing to untangle later. To move forward now, we'll need to settle on where we store the settings for variations. My expectation is that we'll have to include them under Another catch with the merging of settings is how this is impacted when block style variations get nested within other block style variations. Theme.json Partials It's been on the cards for a while that these partials would eventually be a complete theme.json file, including settings. When they get processed and their styles merged into the theme.json under This would come unstuck though if the block style variation settings need to take into account settings for other variations (or blocks with settings within block attributes). Could the next iteration of section styles only support settings that are a result of merging the main theme.json settings with the variation's? Programmatically Registered Block Styles The Theme.json Defined Block Styles Section styles needed to allow block style variations to be defined within a theme style variation's theme.json file. So unlike the theme.json partial, the variation's settings would need to be scoped in a way that maps to the variation. Hence the This is one of the parts that might change depending on how we end up leveraging the global styles CPT in the future. The current style generation for block style variations re-uses the existing theme.json processing for the most part. The inner workings of the theme.json class are getting more and more complex, which adds a little concern around how supporting settings will pan out here. That isn't to say it can't be done just that there is more potential to encounter various hiccups. The proposed enhancement likely provides more direct benefit to theme authors than end users. Could that then mean it would be better to wait until the dust settles on Global Styles & Theme.json: Next Steps after all? |
Sure, I guess for me, addressing #62686 will create these user style variations (with settings) automatically. I thought "settings" missing from the "sections" styles was preventing that work because in my mind, I actually don't see any difference from the sections styles variations or the global styles variations. and ideally I don't see these as nested |
As you note, ideally, these should all be standalone theme.json objects. They can then be composed in many different ways. This is partly why I was cautious around further nesting settings under the main theme.json. I'm not sure if section styles not having their own settings prevents work on #62686 or not. If it helps shed some light on how we get from here to #62686, I'd be happy to explore the changes outlined above and see what that uncovers. |
Part of: #39281
We already allow a block to have the style object of theme.json, but for now, we only accept styles affecting the block itself, not its descendants. E.g., in the group, we can not say the text color of paragraphs nested inside them is X.
We don’t have a settings object, so we can not say the color palette for this section is Y.
This task is about expanding the style shape to support everything theme.json does and a new settings object.
Although the implementation of the settings should be ready to support every setting, I guess we can lock it down at the start to change the color palette and allow to totally disable colors so patterns can provide a more locked experience inside them. I’m not totally sure if we should support every setting so having an initial locked implementation makes sense, and then we can progressively expand what we support and maybe even support everything if we find it makes sense.
There are multiple edge cases, e.g., the theme.json sets a palette specific to the paragraph block, and the section in a pattern sets a palette specific to pattern. A paragraph inside that pattern uses the color palette of the pattern or the global one of the paragraph?
I think the algorithm should be the block uses the closest style/setting specific to that block (first of the pattern than at the global) if there are no block particular values, it uses the closest global value. In the previous sample, it would use the global paragraph color.
In the first version, I expect that we can store styles and settings as just normal block attributes in the HTML comment blob like we do now for styles.
