It affects template structure, PHP output, CSS, and JavaScript behavior.</p>\n<h2>When to Use This Skill</h2>\n<ul>\n<li>Writing <code>header.php</code>, <code>footer.php</code>, <code>index.php</code>, <code>single.php</code>, <code>page.php</code>, or navigation templates.</li>\n<li>Adding a mobile menu, modal, search toggle, carousel, tabs, accordion, or interactive widget.</li>\n<li>Reviewing theme markup for WordPress.org-style accessibility expectations.</li>\n<li>Fixing keyboard navigation, missing focus states, unlabeled controls, bad heading order, or broken landmarks.</li>\n</ul>\n<h2>Document Skeleton</h2>\n<p>A classic theme header should preserve core hooks and language/body helpers.</p>\n<pre><code>&lt;!doctype html&gt;\n&lt;html &lt;?php language_attributes(); ?&gt;&gt;\n&lt;head&gt;\n\t&lt;meta charset=\"&lt;?php bloginfo( 'charset' ); ?&gt;\"&gt;\n\t&lt;meta name=\"viewport\" content=\"width=device-width, initial-scale=1\"&gt;\n\t&lt;?php wp_head(); ?&gt;\n&lt;/head&gt;\n\n&lt;body &lt;?php body_class(); ?&gt;&gt;\n&lt;?php wp_body_open(); ?&gt;\n</code></pre>\n<p>Rules:</p>\n<ul>\n<li>Use <code>language_attributes()</code> on <code>&lt;html&gt;</code>.</li>\n<li>Use <code>bloginfo( 'charset' )</code> for the charset.</li>\n<li>Use <code>wp_head()</code> before closing <code>&lt;/head&gt;</code>.</li>\n<li>Use <code>body_class()</code> on <code>&lt;body&gt;</code>.</li>\n<li>Call <code>wp_body_open()</code> immediately after the opening body tag.</li>\n<li>Add <code>add_theme_support( 'title-tag' )</code> in theme setup; do not hardcode <code>&lt;title&gt;</code>.</li>\n</ul>\n<h2>Landmarks</h2>\n<p>Use semantic landmarks so users can navigate the page structure.</p>\n<pre><code>&lt;header id=\"masthead\" class=\"site-header\"&gt;\n\t&lt;nav id=\"site-navigation\" class=\"main-navigation\" aria-label=\"&lt;?php esc_attr_e( 'Primary menu', 'textdomain' ); ?&gt;\"&gt;\n\t\t...\n\t&lt;/nav&gt;\n&lt;/header&gt;\n\n&lt;main id=\"main\" class=\"site-main\"&gt;\n\t...\n&lt;/main&gt;\n\n&lt;footer id=\"colophon\" class=\"site-footer\"&gt;\n\t...\n&lt;/footer&gt;\n</code></pre>\n<p>Rules:</p>\n<ul>\n<li>Each page should have a clear main landmark.</li>\n<li>Major navigation landmarks need accessible names when there is more than one <code>nav</code>.</li>\n<li>Do not put the entire page in generic <code>&lt;div&gt;</code> elements when semantic elements fit.</li>\n<li>Do not create multiple unlabeled <code>main</code> elements.</li>\n</ul>\n<h2>Skip Links</h2>\n<p>Add a skip link that becomes visible on focus and targets real content.</p>\n<pre><code>&lt;a class=\"skip-link screen-reader-text\" href=\"#main\"&gt;\n\t&lt;?php esc_html_e( 'Skip to content', 'textdomain' ); ?&gt;\n&lt;/a&gt;\n</code></pre>\n<p>The target must exist. If focus needs to move reliably in JavaScript-assisted layouts, make the target focusable:</p>\n<pre><code>&lt;main id=\"main\" class=\"site-main\" tabindex=\"-1\"&gt;\n</code></pre>\n<p>Rules:</p>\n<ul>\n<li>The skip link must be the first meaningful focusable element after <code>wp_body_open()</code>.</li>\n<li>It must become visible on keyboard focus.</li>\n<li>The <code>href</code> must point to an ID that exists on every template.</li>\n</ul>\n<h2>Screen Reader Text CSS</h2>\n<p>Include a standard visually-hidden utility and restore it on focus.</p>\n<pre><code>.screen-reader-text {\n\tposition: absolute;\n\twidth: 1px;\n\theight: 1px;\n\tpadding: 0;\n\tmargin: -1px;\n\toverflow: hidden;\n\tclip: rect(1px, 1px, 1px, 1px);\n\tword-wrap: normal;\n\tborder: 0;\n}\n\n.screen-reader-text:focus {\n\ttop: 5px;\n\tleft: 5px;\n\tz-index: 100000;\n\tdisplay: block;\n\twidth: auto;\n\theight: auto;\n\tpadding: 15px 23px 14px;\n\tclip: auto;\n\tbackground: #fff;\n\tcolor: #000;\n\tfont-size: 1rem;\n\tfont-weight: 700;\n\ttext-decoration: none;\n}\n</code></pre>\n<p>Rules:</p>\n<ul>\n<li>Do not use <code>display: none</code> for content that screen readers need.</li>\n<li>Make skip links visible on focus, not only available to assistive tech.</li>\n<li>Keep focus styles visible above sticky headers.</li>\n</ul>\n<h2>Headings</h2>\n<p>Headings describe document structure.</p>\n<p>Rules:</p>\n<ul>\n<li>Use one clear <code>h1</code> for the primary page title.</li>\n<li>Archive/search pages usually use the archive/search title as <code>h1</code>.</li>\n<li>Posts in archive cards should usually use <code>h2</code>.</li>\n<li>Do not choose heading levels based only on font size.</li>\n<li>Do not skip levels to achieve visual styling; style with CSS.</li>\n</ul>\n<h2>Links, Buttons, and Toggles</h2>\n<p>Use elements by behavior:</p>\n<ul>\n<li>Links navigate to URLs.</li>\n<li>Buttons perform actions on the current page.</li>\n<li>Form controls collect input.</li>\n</ul>\n<p>Mobile menu toggle:</p>\n<pre><code>&lt;button\n\tclass=\"menu-toggle\"\n\ttype=\"button\"\n\taria-controls=\"primary-menu\"\n\taria-expanded=\"false\"\n&gt;\n\t&lt;?php esc_html_e( 'Menu', 'textdomain' ); ?&gt;\n&lt;/button&gt;\n</code></pre>\n<p>Rules:</p>\n<ul>\n<li>Do not use <code>&lt;a href=\"#\"&gt;</code> as a button.</li>\n<li>Keep visible labels or accessible names for icon-only buttons.</li>\n<li>Update <code>aria-expanded</code> when a controlled region opens/closes.</li>\n<li><code>aria-controls</code> must reference an existing ID.</li>\n<li>Avoid adding ARIA when native HTML already communicates the behavior correctly.</li>\n</ul>\n<h2>Focus and Keyboard</h2>\n<p>Rules:</p>\n<ul>\n<li>Never remove <code>outline</code> without a visible replacement.</li>\n<li>Use <code>:focus-visible</code> where appropriate, with a fallback if supporting older browsers.</li>\n<li>Hover-only menus are not enough. Keyboard users must be able to open and traverse navigation.</li>\n<li>Modals and off-canvas panels need focus management and Escape behavior. If the theme cannot implement that correctly, avoid shipping the interaction.</li>\n<li>Do not trap focus in ordinary dropdown navigation.</li>\n</ul>\n<h2>Forms and Search</h2>\n<p>Rules:</p>\n<ul>\n<li>Every input needs a real <code>&lt;label&gt;</code> or an equivalent accessible name.</li>\n<li>Placeholder text is not a label.</li>\n<li>Error messages should identify the field and be programmatically connected when possible.</li>\n<li>Use <code>get_search_form()</code> unless the theme has a specific accessible custom search form.</li>\n<li>Nonces and validation are security concerns, but accessible errors are still required for user correction.</li>\n</ul>\n<h2>Images and Icons</h2>\n<p>Rules:</p>\n<ul>\n<li>Informative images need useful alt text.</li>\n<li>Decorative images should use empty alt text.</li>\n<li>Do not stuff keywords into alt text.</li>\n<li>For featured images, rely on WordPress image functions where possible and ensure attachment alt text is maintained.</li>\n<li>SVG icons used only as decoration should have <code>aria-hidden=\"true\"</code> and <code>focusable=\"false\"</code>.</li>\n<li>Icon-only buttons/links need an accessible name via visible text, <code>.screen-reader-text</code>, or <code>aria-label</code>.</li>\n</ul>\n<h2>Motion and Visual Requirements</h2>\n<p>Respect reduced motion preferences.</p>\n<pre><code>@media (prefers-reduced-motion: reduce) {\n\t*,\n\t*::before,\n\t*::after {\n\t\tscroll-behavior: auto !important;\n\t\tanimation-duration: 0.01ms !important;\n\t\tanimation-iteration-count: 1 !important;\n\t\ttransition-duration: 0.01ms !important;\n\t}\n}\n</code></pre>\n<p>Rules:</p>\n<ul>\n<li>Ensure text contrast is sufficient in normal, hover, and focus states.</li>\n<li>Do not rely on color alone to communicate state.</li>\n<li>Keep line heights and spacing readable.</li>\n<li>Avoid auto-playing motion-heavy UI. If used, provide pause/stop controls.</li>\n</ul>\n<h2>WordPress Template Helpers</h2>\n<p>Preserve helpers that contribute useful classes and core integration:</p>\n<ul>\n<li><code>body_class()</code> on <code>&lt;body&gt;</code>.</li>\n<li><code>post_class()</code> on post wrappers.</li>\n<li><code>wp_body_open()</code> after <code>&lt;body&gt;</code>.</li>\n<li><code>wp_head()</code> and <code>wp_footer()</code>.</li>\n<li><code>language_attributes()</code> on <code>&lt;html&gt;</code>.</li>\n<li><code>the_custom_logo()</code> when using core custom logo support.</li>\n<li><code>get_search_form()</code> for baseline search form behavior.</li>\n</ul>\n<h2>Review Checklist</h2>\n<ul>\n<li>Header uses <code>language_attributes()</code>, <code>wp_head()</code>, <code>body_class()</code>, and <code>wp_body_open()</code>.</li>\n<li>Page has one clear main landmark.</li>\n<li>Skip link exists, is focus-visible, and points to a real ID.</li>\n<li>Navigation landmarks have accessible names.</li>\n<li>Mobile toggles are buttons and update <code>aria-expanded</code>.</li>\n<li>Keyboard focus is visible everywhere.</li>\n<li>Headings follow document structure.</li>\n<li>Forms have labels and understandable errors.</li>\n<li>Images and SVG icons have appropriate alt/ARIA behavior.</li>\n<li>Reduced motion is respected for animations/transitions.</li>\n<li>Theme does not rely on hover-only interactions.</li>\n</ul>\n<h2>Common Mistakes</h2>\n<ul>\n<li>Hiding skip links with <code>display: none</code>.</li>\n<li>Removing outlines globally.</li>\n<li>Using a fake link for menu/search toggles.</li>\n<li>Adding <code>role=\"button\"</code> to an anchor instead of using a button.</li>\n<li>Creating several unlabeled navigation landmarks.</li>\n<li>Outputting icon-only buttons with no accessible name.</li>\n<li>Making dropdown menus impossible to use with a keyboard.</li>\n<li>Forgetting <code>wp_body_open()</code> in <code>header.php</code>.</li>\n</ul>\n<h2>References</h2>\n<ul>\n<li>Official documentation: <a href=\"https://developer.wordpress.org/themes/functionality/accessibility/\">https://developer.wordpress.org/themes/functionality/accessibility/</a></li>\n<li>Official documentation: <a href=\"https://developer.wordpress.org/themes/classic-themes/basics/template-tags/\">https://developer.wordpress.org/themes/classic-themes/basics/template-tags/</a></li>\n<li>Verified source paths:\n<ul>\n<li><code>wp-includes/general-template.php</code></li>\n<li><code>wp-includes/post-template.php</code></li>\n<li><code>wp-includes/nav-menu-template.php</code></li>\n<li><code>wp-includes/class-walker-nav-menu.php</code></li>\n<li><code>wp-content/themes/storefront/inc/structure/header.php</code></li>\n<li><code>wp-content/themes/generatepress/header.php</code></li>\n</ul>\n</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":9229,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
