4WP Responsive Plugin

# 4WP Responsive

Responsive controls for core Gutenberg blocks with per-breakpoint spacing, visibility, font-size, and alignment support. Designed to be theme.json-first and editor-friendly.

## Documentation

– Plugin page: https://4wp.dev/plugin/4wp-responsive/

– GitRepository: https://github.com/4wpdev/4wp-responsive

## What it does today

– Responsive spacing per breakpoint (Padding/Margin: top/right/bottom/left).

– Responsive visibility per breakpoint (Hide / Show only).

– Responsive font-size per breakpoint for blocks that support typography.

– Responsive text alignment per breakpoint (left/center/right/justify).

– Works with core blocks (e.g. Heading, Paragraph, Group, List) and any block that supports the same features.

– Uses utility CSS classes + CSS variables (no frontend JS).

– Editor preview stays in sync with the selected device mode.

## Advantages

– Theme.json-first: reads spacing and font-size presets from the active theme.

– Works with standard blocks (no custom block requirement).

– Minimal markup changes: classes + CSS variables only.

– Safe fallback: content stays intact if the plugin is deactivated.

– Single generated CSS file, cached with a hash.

## How it works

– Presets (from theme.json) are applied via utility classes like:

– has-forwp-padding-top-mobile-40

– has-forwp-font-size-desktop-large

– has-forwp-text-align-mobile-center

– Custom values (e.g. 150 / 150px / 2rem) are applied via:

– class has-forwp-*-custom

– CSS variable on the block, e.g. –forwp-padding-top-mobile: 150px;

– this keeps output clean while allowing arbitrary values

## Editor UI

You will find Responsive Spacing in the block inspector sidebar:

– Tabs: Desktop / Tablet / Mobile

– Sections: Padding, Margin, Font Size, Alignment, Visibility

– Current screen size is shown per tab

– Hidden blocks are dimmed in the editor instead of fully removed

## Settings

Settings → 4WP Responsive

### Breakpoints

Displayed in a table with the active source:

– theme.json (`settings.custom.breakpoints`), if present

– Plugin settings, only when theme.json has no breakpoints

– Default values if neither is available

If the theme defines breakpoints, custom fields are disabled to avoid conflicts.

### CSS storage path

Generated CSS is stored in wp-content/uploads/4wp-responsive/ by default.

You can override the storage path with an absolute path if your architecture requires it.

## Requirements

– WordPress 6.0+

– PHP 7.4+

– A theme with theme.json is recommended (for presets).

## Notes

– The plugin respects theme.json presets for spacing and font sizes.

– Custom values are supported, but only through CSS variables (no inline padding/margin).
