Global Styles Global Styles provides reusable colour variables, typography settings, and button presets. Custom colours can be referenced as CSS variables throughout LNBuilder output. Performance

• Frontend output uses semantic HTML and scoped CSS where applicable.
• Frontend interactions use vanilla JavaScript.
• WordPress hooks and APIs are used for saving, rendering, and administration.

3.9.9

• Text domain restored to lnbuilder-visual-page-builder (the slug WordPress.org assigned), in the plugin header and all 29 translation calls; the package folder and main file are named to match.
• Security: element ids are now limited to letters, digits, "_" and "-" (they were written into id="" attributes and CSS selectors, so a crafted id could inject site-wide CSS rules).
• Security: free-text style values (border, shadow, gradient, filter) are now checked against a strict allow-list and rejected if they contain anything else, instead of being partly cleaned.
• Security: background-image URLs are quoted and encoded so a URL can no longer inject extra style declarations.
• Fixed six more style values that were not validated as CSS: slider button 2 background and border, slider tablet/mobile heights, divider line style, form button alignment.

3.9.8

• The Form widget's redirect URL is limited to http(s) and relative URLs; the HTML widget is filtered when displayed as well as when saved; admin scripts no longer evaluate code; fixed the editor's Page Settings button.

3.9.7

• Text domain changed to lnbuilder-updated.

3.9.6

• Video widget iframes are limited to known video providers (YouTube, Vimeo, Wistia, Loom, Dailymotion, Twitch).
• Map widget latitude/longitude are validated as real coordinates.

3.9.5

• Fixed an XSS issue: border/shadow/gradient/filter values could contain a quote character and break out of their style attribute. Quotes are now stripped.

3.9.0 - 3.9.4

• Border in Global Styles is now width/style/color controls; fixed a crash when a button style had a background color; more CSS value validation; admin styling moved into CSS classes; sanitization fix on the border-style field.

3.8.3 - 3.8.9

• Fixed the Icon, Audio and Input elements (they had no frontend output); validated CSS values across all widgets; removed inline JavaScript handlers from the admin editor.

3.8.0 - 3.8.2

• Completed the internal prefix migration (vcb_ to lnbld_) across hooks, handles, database tables/options/meta keys, with a safe one-time migration for existing sites.

3.7.9

• Removed remaining raw inline <style> tag fallbacks in favor of the standard WordPress style-enqueue APIs.

3.7.8

• Removed free-text per-element CSS fields (Custom/Hover/Tablet/Mobile/Animation CSS) from the builder entirely.

3.7.7

• Fixed the root cause of "critical error" reports: a division-by-zero in the responsive grid-column CSS generator.

3.7.6

• Removed the Global Styles Custom CSS textarea and the unfiltered_html exception on the HTML widget.

3.7.5

• Replaced esc_attr() with proper CSS-value validation throughout the Global Styles output.

3.7.0 - 3.7.4

• UI fixes and additions: button icon/hover colors, form step-indicator color, Text Domain header correction, fixed JS errors in the Button widget's Style panel.

3.6.5 - 3.6.9

• Bundled third-party libraries locally instead of loading from a CDN; sanitized the HTML widget and custom CSS fields; added nonce checks; fixed prefix and Text Domain warnings; fixed a broken Global Styles button.

3.6.0

• Added Logo Slider and Image Carousel widgets with responsive controls.

3.5.9

• Updated plugin metadata, slider/accordion/list widget controls, and general compatibility fixes.
