HTML/CSS service landing page — original demo
Stephen Tumblin
Original service landing page
A builtbycircuit portfolio demonstration, created with AI assistance and reviewed. This is the website layer of the same synthetic data-cleanup demo shown elsewhere in this portfolio, not a separate client engagement.
The problem
A small data service needs to explain its scope and show what its output looks like before asking for a project brief.
What was built
A lightweight HTML/CSS/JavaScript page with a service introduction, input/accepted/review sample views, downloadable Python and JSON examples, a process section and a concise inquiry outline. It uses responsive layout rules, semantic headings, labeled controls, visible keyboard-focus styling and text-safe rendering.
Checks and limits
The desktop sample controls and download destinations were checked. The six-row example reconciles to two accepted rows and four retained review rows, preserving zero values and conflicting records. Mobile layout was not separately verified. There is no upload, payment checkout or live-system integration.
