For a longer history or roadmap with many entries, alternating events left and right of a central line makes better use of horizontal space and creates a more visually engaging zigzag pattern than a single-column vertical list.
Enter your dated events, and this tool generates an alternating layout where odd-numbered entries appear on the left and even-numbered entries on the right of a central vertical line, with a live preview and the matching HTML and CSS to copy.
This layout works particularly well for a desktop-width company history or product roadmap page; on narrow mobile screens, the alternating pattern typically needs to collapse into a single column, which you'd handle with a responsive media query in your actual implementation.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.
Bookmark this page if you expect to use this tool regularly — it loads fast and behaves the same way every time, with no account needed.
This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
Frequently asked questions
Does this layout work well on mobile screens?
The alternating two-column pattern is best suited to wider screens; for mobile, you'd typically add a media query collapsing it into the single-column vertical timeline pattern instead.
Can I add more than four events?
Yes, add as many event lines as you need — the alternating pattern continues automatically for any number of entries.
