Use when creating or reviewing a block theme, theme.json, Global Styles variation, responsive block styling, or WordPress 7.1 design controls.\nlicense: GPLv2-or-later\nmetadata:\nwp-skills-author: \"Soczó Kristóf\"\nwp-skills-contact: \"mailto:lonsdale201@hotmail.com\"\nwp-skills-plugin: \"wordpress\"\nwp-skills-plugin-version-tested: \"7.1\"\nwp-skills-wp-version-tested: \"7.1\"\nwp-skills-php-min: \"7.4\"\nwp-skills-last-updated: \"2026-08-19\"</h2>\n<h1>Block Theme Global Styles</h1>\n<p>Use <code>theme.json</code> as structured design data, not as a place to paste arbitrary CSS. WordPress merges core defaults, theme data, child-theme data, user Global Styles, and block-level styles; verify both editor and front-end output after every structural change.</p>\n<h2>Start with the supported schema</h2>\n<p>WordPress 7.1 still uses theme.json schema version <code>3</code>:</p>\n<pre><code>{\n  \"$schema\": \"https://schemas.wp.org/trunk/theme.json\",\n  \"version\": 3,\n  \"settings\": {},\n  \"styles\": {}\n}\n</code></pre>\n<p>Use the trunk schema while developing against the current WordPress release, and validate the file as JSON. The schema version and WordPress release number are separate concepts; do not write <code>\"version\": 7.1</code>.</p>\n<h2>Model responsive styles as states</h2>\n<p>WordPress 7.1 introduces global <code>settings.viewport</code> breakpoints and <code>@mobile</code> / <code>@tablet</code> style-state nodes:</p>\n<pre><code>{\n  \"version\": 3,\n  \"settings\": {\n    \"viewport\": {\n      \"mobile\": \"480px\",\n      \"tablet\": \"782px\"\n    }\n  },\n  \"styles\": {\n    \"blocks\": {\n      \"core/group\": {\n        \"spacing\": { \"padding\": { \"left\": \"3rem\", \"right\": \"3rem\" } },\n        \"@tablet\": {\n          \"spacing\": { \"padding\": { \"left\": \"2rem\", \"right\": \"2rem\" } }\n        },\n        \"@mobile\": {\n          \"spacing\": { \"padding\": { \"left\": \"1rem\", \"right\": \"1rem\" } }\n        }\n      }\n    }\n  }\n}\n</code></pre>\n<p>The default breakpoints are <code>480px</code> and <code>782px</code>. With both present:</p>\n<ul>\n<li><code>@mobile</code> means <code>width &lt;= mobile</code>;</li>\n<li><code>@tablet</code> means <code>mobile &lt; width &lt;= tablet</code>;</li>\n<li>base styles remain the desktop/default layer.</li>\n</ul>\n<p>Only non-negative numeric <code>px</code>, <code>em</code>, and <code>rem</code> values are accepted (the core\nregular expression also accepts zero). Percentages, CSS functions, variables,\nunsupported keys, and non-string values are discarded. If no custom value is\nvalid, core restores both defaults. If tablet is not larger than mobile, tablet\nis omitted. A single valid breakpoint gets one max-width query rather than\nbeing merged with a missing default.</p>\n<p>Viewport settings are global-only; do not put <code>settings.viewport</code> below an individual block. Responsive state styles can appear on blocks, their elements, and registered block style variations. Read <a href=\"references/theme-json-71.md\">references/theme-json-71.md</a> before designing nested state structures.</p>\n<p>To remove only the 7.1 responsive-editing controls from the editor, filter\n<code>block_editor_settings_all</code> and set <code>responsiveEditingEnabled</code> to <code>false</code>.\nThis hides the responsive-style entry points; it does not delete saved states,\nstop their CSS from rendering, or disable device previews. Treat it as editor\npolicy, not a content restriction.</p>\n<h2>Use only supported style states</h2>\n<p>Element states remain under an element:</p>\n<pre><code>{\n  \"styles\": {\n    \"elements\": {\n      \"link\": {\n        \":hover\": { \"color\": { \"text\": \"var:preset|color|contrast\" } },\n        \"@mobile\": { \"typography\": { \"textDecoration\": \"underline\" } }\n      }\n    }\n  }\n}\n</code></pre>\n<p>WordPress accepts block pseudo-states only for block types on its allowlist. In WordPress 7.1 these are <code>core/button</code> and <code>core/navigation-link</code>, with <code>:hover</code>, <code>:focus</code>, <code>:focus-visible</code>, and <code>:active</code>.</p>\n<p>The new <code>-current</code> custom state is restricted to <code>core/navigation-link</code> and maps to that block's registered current-menu selector:</p>\n<pre><code>{\n  \"styles\": {\n    \"blocks\": {\n      \"core/navigation-link\": {\n        \"-current\": {\n          \"typography\": { \"fontWeight\": \"700\" },\n          \":hover\": { \"typography\": { \"textDecoration\": \"underline\" } }\n        }\n      }\n    }\n  }\n}\n</code></pre>\n<p>Do not invent state keys or assume a third-party block's <code>selectors.states</code> makes it valid in Global Styles. WordPress 7.1 validates custom block states against a core allowlist; unsupported nodes are removed during theme.json processing.</p>\n<h2>Adopt new supports without confusing settings and values</h2>\n<p>WordPress 7.1 adds these relevant design capabilities:</p>\n<ul>\n<li><code>settings.background.gradient</code>: exposes the new background-gradient support for blocks that declare it;</li>\n<li><code>settings.dimensions.minWidth</code>: enables minimum-width support where the block declares it;</li>\n<li><code>settings.blockVisibility.allowEditing</code>: controls whether editors may change block visibility;</li>\n<li><code>styles.*.typography.textShadow</code>: supplies a CSS text-shadow value through theme.json.</li>\n</ul>\n<p>Support flags enable controls; actual values belong under <code>styles</code> or per-block attributes. Example:</p>\n<pre><code>{\n  \"version\": 3,\n  \"settings\": {\n    \"background\": { \"gradient\": true },\n    \"dimensions\": { \"minWidth\": true },\n    \"blockVisibility\": { \"allowEditing\": true }\n  },\n  \"styles\": {\n    \"blocks\": {\n      \"core/group\": {\n        \"background\": {\n          \"gradient\": \"linear-gradient(135deg, #111 0%, #444 100%)\"\n        },\n        \"dimensions\": { \"minWidth\": \"18rem\" }\n      },\n      \"core/heading\": {\n        \"typography\": { \"textShadow\": \"0 1px 2px rgb(0 0 0 / 0.25)\" }\n      }\n    }\n  }\n}\n</code></pre>\n<p><code>background.gradient</code> is different from the older color-gradient preset system. When the new background-gradient value is set, it owns the background-image output; image and gradient values may also be combined by core. Test KSES filtering of any value built from dynamic input.</p>\n<h2>Respect merge order and the cascade</h2>\n<ul>\n<li>Base styles and responsive styles coexist; a breakpoint does not replace the complete block style object.</li>\n<li>User Global Styles can override theme values. Test with and without user customizations.</li>\n<li>Responsive pseudo-state CSS is emitted late enough to win against the equivalent base pseudo-state, but higher-specificity plugin/theme CSS can still win.</li>\n<li>WordPress 7.1 wraps block-level preset selectors in <code>:where()</code>, lowering\ntheir specificity to the same <code>0-1-0</code> as root preset classes. Audit custom\n<code>!important</code> CSS that relied on the old block selector winning a tie.</li>\n<li>Style variations can contain responsive states, elements, and inner block styles, but nested variations are not valid.</li>\n<li>Never depend on private editor settings or generated class-name details when the public theme.json structure is sufficient.</li>\n</ul>\n<p>Template Parts use content-only editing by default. A theme or plugin can set\n<code>disableContentOnlyForTemplateParts</code> through <code>block_editor_settings_all</code> to\nrestore standard block editing, but template-locked rendering overrides that\nchoice. Treat this as editor UX policy, not a content-security control.</p>\n<h2>Validate behavior, not just JSON syntax</h2>\n<ol>\n<li>Validate JSON and the theme.json schema.</li>\n<li>Load the parsed data through <code>WP_Theme_JSON</code> or <code>WP_Theme_JSON_Resolver</code> and inspect what survives sanitization.</li>\n<li>Inspect generated CSS for desktop, mobile, tablet, pseudo-state, and custom-state rules.</li>\n<li>Compare the Site Editor canvas and the front end at boundary widths.</li>\n<li>Test child-theme and user Global Styles overrides.</li>\n<li>Confirm keyboard focus, current-navigation indication, contrast, and reduced-motion behavior independently of visual hover styles.</li>\n</ol>\n<p>Do not use responsive styling to hide security-sensitive content. CSS and block visibility are presentation controls, not authorization.</p>\n<h2>Related skills</h2>\n<ul>\n<li>Use <code>wp-block-editor-iframe-compatibility</code> when editor assets or DOM code must work inside the editor canvas iframe.</li>\n<li>Use <code>wp-block-registration-and-assets</code> for server/client block registration and asset handles.</li>\n<li>Use <code>classic-theme-assets-build</code> only for classic-theme asset pipelines; it does not replace theme.json validation.</li>\n</ul>\n<h2>References</h2>\n<ul>\n<li>Responsive styles and viewports: <a href=\"https://make.wordpress.org/core/2026/08/05/responsive-block-styles-and-configurable-viewports-in-wordpress-7-1/\">https://make.wordpress.org/core/2026/08/05/responsive-block-styles-and-configurable-viewports-in-wordpress-7-1/</a></li>\n<li>Pseudo and custom states: <a href=\"https://make.wordpress.org/core/2026/08/05/pseudo-and-custom-style-states-in-wordpress-7-1/\">https://make.wordpress.org/core/2026/08/05/pseudo-and-custom-style-states-in-wordpress-7-1/</a></li>\n<li>Miscellaneous editor changes: <a href=\"https://make.wordpress.org/core/2026/08/04/miscellaneous-block-editor-changes-in-wordpress-7-1/\">https://make.wordpress.org/core/2026/08/04/miscellaneous-block-editor-changes-in-wordpress-7-1/</a></li>\n</ul>\n","files":[{"path":"agents/openai.yaml","sizeBytes":278,"isText":true},{"path":"references/theme-json-71.md","sizeBytes":3198,"isText":true},{"path":"SKILL.md","sizeBytes":8659,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
