The Anchor Gutenberg block by Getwid WordPress blocks allows you to create anchor links for performing quick jumps from one part of the page to another (internal links).
The core Heading Gutenberg block also allows you to create anchors in WordPress, but it works for heading destinations only.
The Anchor block by Getwid is, however, more flexible – it can help you place anchors next to any content element (galleries, sliders, banners, etc.), not limiting you to just headings. That is, you can link one button to another button, etc.
