A compact subscribe box with a thumbnail that slides into the bottom-right corner once the reader has scrolled half of a blog article. It is a labelled complementary region rather than a modal, so it never takes focus, and it can be dismissed with the close button or Esc, with the dismissal remembered for the session in sessionStorage. On phones it becomes a full-width bottom sheet, and with reduced motion it appears without sliding.

It is plain HTML and CSS plus a few lines of vanilla JavaScript: no jQuery, no Bootstrap files, no plugins, and the download is 352 KB. Use it on its own, or drop it into a Bootstrap 4, 5 or 6 project and it looks the same.

• Appears after a configurable scroll depth (data-threshold)
• Non-modal complementary region that never steals focus
• Close button and Esc dismissal remembered in sessionStorage
• Inline email validation with a focused success message
• Bottom-sheet layout on phones with no overflow
• Slide-in animation that is removed for reduced motion
