Responsive Block Control – Hide blocks based on display width

Responsive Block Control adds responsive toggles to a “Visibility” panel of the block editor, to show or hide blocks according to screen width.

Security

Version 1.3.1 resolves a stored cross‑site scripting (XSS) vulnerability (CVE‑2025‑62135) affecting earlier versions (<= 1.2.9). Users with contributor access or higher should update immediately.

If you discover a security vulnerability, please report it responsibly to: security@saschapaukner.de

Limitations

Does not work with the Classic Block, Widget Block or Widget Area Block [‘core/freeform’, ‘core/legacy-widget’, ‘core/widget-area’], as the those blocks do not support block attributes. Does also not work with the HTML Block [‘core/html’] inside the Widget Screen, as this one also does not support block attributes there.

Configuration

Override existing breakpoints

function override_responsive_block_control_breakpoints($break_points) { $break_points['base'] = 0; $break_points['mobile'] = 400; $break_points['tablet'] = 800; $break_points['desktop'] = 1000; $break_points['wide'] = 1600; return $break_points; } add_filter('responsive_block_control_breakpoints', 'override_responsive_block_control_breakpoints');

Provide custom CSS

You can provide your own CSS rules per breakpoint using the new filter responsive_block_control_custom_css_rules.

add_filter('responsive_block_control_custom_css_rules', function($rules) { return [ 'mobile' => 'display: none !important;', 'tablet' => 'display: none !important;', 'desktop' => 'display: none !important;', 'wide' => 'display: none !important;', ]; });

Stop css output completely

function override_responsive_block_control_add_css() { return false; } add_filter('responsive_block_control_breakpoints', 'override_responsive_block_control_add_css');
