SnapSection is a WordPress plugin that allows users to share specific sections from your article or blog post swiftly.

It appends the id attribute of the SnapSection element (the default one is the h2, but you can also select h1, h3, h4, or .cwss-element) to your page’s URL. Consequently, any user who clicks the link will be directed to this specific section of your page or post.

Once an ID is assigned, users can share the link to a specific section of your page by hovering over it and clicking the displayed icon. Users who access the shared URL will be directed to the corresponding section of your post or article.
