Wp css override

WordPress Plugin CSS Override Skill

Overview

This skill produces accurate, scoped, !important-free CSS overrides for WordPress plugins in a Divi child theme environment. The key problem it solves: AI cannot see the rendered DOM or computed cascade, so it must reconstruct specificity context from source files and a captured HTML snapshot.

---

Step 1 — Orient to the project

Before writing any CSS, read the following in order:

1. Child theme stylesheet — find it at wp-content/themes/[child-theme]/style.css or assets/css/style.css (path varies per project — check theme root first)
2. Plugin source stylesheet — typically at wp-content/plugins/[plugin-slug]/assets/css/ or similar. Use find if unsure:

   find wp-content/plugins/[plugin-slug] -name "*.css" | head -20
   

3. dev-notes/ folder in the theme root — check for any existing snapshots or notes about this plugin:

   ls wp-content/themes/[child-theme]/dev-notes/
   

4. Body class — if not in dev-notes, ask the user to paste it, or find it in a PHP template:

   grep -r "body_class" wp-content/themes/[child-theme]/ --include="*.php"
   

Brand scope class: bd324-branded — all overrides must be scoped under this.

---

Step 2 — Get the rendered HTML snapshot

Claude Code cannot see the browser DOM. A rendered HTML snapshot of the plugin component is required for accurate selector targeting.

Check dev-notes first:

ls wp-content/themes/[child-theme]/dev-notes/
# Look for [plugin-slug]-rendered.html or similar

If no snapshot exists, ask the user to:

1. Load the page in a browser
2. DevTools → right-click the plugin's outermost wrapper element
3. Copy → Copy element
4. Save to wp-content/themes/[child-theme]/dev-notes/[plugin-slug]-rendered.html

Do not proceed to write overrides without either the snapshot or confirmation from the user that they want a best-effort attempt from source CSS alone.

---

Step 3 — Identify what's actually winning the cascade

With source CSS and rendered HTML in hand, identify:

• Which selectors the plugin uses (from source CSS)
• Which selectors Divi may be applying to inputs/forms (Divi normalises form elements heavily — check wp-content/themes/Divi/style.css or compiled output)
• Whether the plugin injects inline styles via PHP (grep for style= in rendered HTML)

# Quick check for inline styles in snapshot
grep -o 'style="[^"]*"' wp-content/themes/[child-theme]/dev-notes/[plugin-slug]-rendered.html

Inline styles require either a JS override or a structural workaround — flag these to the user before writing CSS.

---

Step 4 — Determine the output file

Ask the user or check for an existing override file structure. Common patterns:

# Pattern A — flat CSS
wp-content/themes/[child-theme]/css/[plugin-slug]-overrides.css

# Pattern B — Sass partials
wp-content/themes/[child-theme]/sass/overrides/_[plugin-slug].scss
wp-content/themes/[child-theme]/scss/overrides/_[plugin-slug].scss
wp-content/themes/[child-theme]/assets/css/overrides/_[plugin-slug].scss

Check whether a build step exists:

ls wp-content/themes/[child-theme]/
# Look for package.json, Gruntfile.js, gulpfile.js, webpack.config.js

If Sass is compiled, write .scss. If no build step, write plain .css.

If no override file exists yet, create it in the most logical location given the existing structure. Always confirm path with the user before writing.

---

Step 5 — Write the overrides

Rules:

• Scope everything under body.bd324-branded .wpcf7 (or the plugin's wrapper class)
• No !important — use specificity only
• If !important is unavoidable (e.g. inline styles), add a comment:

  /* !important required — plugin injects inline style via PHP */
  

• Group by element type with a comment header for each group
• Do not reset or override styles unrelated to the target design

Specificity pattern (when Divi is fighting you):

/* One extra layer beats Divi's selectors in most cases */
body.bd324-branded .plugin-wrapper .element { }

/* For stubborn Divi form normalisation */
body.bd324-branded #page .plugin-wrapper input[type="text"] { }

Output structure:

/* ==========================================================================
   [Plugin Name] Overrides
   Scoped under: body.bd324-branded
   Source snapshot: dev-notes/[plugin-slug]-rendered.html
   ========================================================================== */

/* Labels
   ========================================================================== */

/* Inputs
   ========================================================================== */

/* Textarea
   ========================================================================== */

/* Select
   ========================================================================== */

/* Submit button
   ========================================================================== */

/* Response / validation messages
   ========================================================================== */

---

Step 6 — Enqueue the override file

Check how the child theme enqueues styles:

grep -n "wp_enqueue_style" wp-content/themes/[child-theme]/functions.php

Add enqueue using the bd324_ prefix and include a docblock:

/**
 * Enqueue [Plugin Name] override styles.
 *
 * @return void
 */
function bd324_enqueue_[plugin_slug]_overrides() {
    wp_enqueue_style(
        'bd324-[plugin-slug]-overrides',
        get_stylesheet_directory_uri() . '/[path/to/override.css]',
        array( 'bd324-main-style' ),
        wp_get_theme()->get( 'Version' )
    );
}
add_action( 'wp_enqueue_scripts', 'bd324_enqueue_[plugin_slug]_overrides' );

If the project uses a central enqueue function, add to it rather than creating a new one. Check first:

grep -n "wp_enqueue_scripts" wp-content/themes/[child-theme]/functions.php

---

Debugging aid

If the user reports styles still not applying after override, suggest adding this temporarily to isolate what's winning:

/* TEMP DEBUG — remove before commit */
body.bd324-branded .plugin-wrapper * {
    outline: 2px solid red !important;
}

Then in DevTools → Computed tab → filter by the property in question — the winning rule and its source file will be visible.

Plugin-specific notes

Contact Form 7

• Wrapper class: .wpcf7
• CF7's own stylesheet is minimal — the real fight is usually Divi's form normalisation
• Submit button renders as input[type="submit"] not <button> — target accordingly
• Response messages: .wpcf7-response-output

Estatik

• Check rendered HTML — Estatik class names are not always obvious from source
• Estatik uses .estatik-wrapper as outer scope in most versions
• Property listing grid: .es-listings, single listing: .es-property

Gravity Forms

• Wrapper: .gform_wrapper
• Divi and GF both apply heavy form styles — expect specificity battles
• GF uses ul/li for field layout — don't assume div structure

Notes on this skill

• PHP version: Do not add type hints to PHP unless the user confirms the version
• Sass vs CSS: Always check for a build step before choosing output format
• No assumptions about assets path — always check actual theme structure first
• dev-notes/ is the handoff point between browser inspection and Claude Code
