Slide-in Form
A slide-in form is a lead-capture form that animates into view from the edge of the screen, typically a corner, without covering the entire page.
In depth
A slide-in form, sometimes called a scroll box, appears from a screen edge as the visitor scrolls past a defined trigger point, usually occupying a corner rather than the full viewport. This makes it a gentler middle ground between an unobtrusive inline form and a full-screen popup: it draws the eye and demands a small decision, yet leaves the content visible so the visitor never feels fully blocked. Timing is the lever, since firing the slide-in after the visitor has read a meaningful portion of the page signals genuine interest rather than interrupting a first impression.
The common pitfall is poor placement that overlaps key buttons or mobile navigation, which frustrates users and can be misread as an intrusive interstitial. In a quiz-funnel workflow, a slide-in form is ideal for a low-pressure secondary call to action, for example a corner box that appears at 50% scroll inviting the reader to 'Take the 2-minute readiness quiz.' Because it respects the reading experience while still being clearly visible, the slide-in tends to capture more leads than a footer form without the dismissal friction of an overlay.
Example in practice
Frequently asked questions
How is a slide-in form different from a popup?
A slide-in animates into a corner and leaves most content visible, while a popup overlays the whole page. The slide-in is gentler and tends to feel less interruptive to visitors.
When should a slide-in form be triggered?
Trigger it after the visitor has scrolled through a meaningful portion of the page, such as 40-60% scroll depth. That timing signals genuine interest rather than interrupting the first impression.
Can a slide-in form lead into a quiz funnel?
Yes. A slide-in is a great low-pressure invitation to take a short scorecard. The reader clicks, completes the quiz, and enters your funnel as a pre-qualified lead.
