Leave HTML that the next person can understand
By Gyata Tabiri · Revised November 2, 2026
A project will eventually need another update, and the person making it may not be the person who built it. I care about the structure and context that make that next change understandable.
Make the document readable
Use meaningful headings, labels, link text, and a sensible reading order. Group related content because it belongs together, not simply because the current screen arrangement puts it nearby. An understandable source helps a maintainer ask the right questions.
Separate shared rules from exceptions
Keep reusable patterns recognizable. If a particular section needs a workaround, explain the constraint close to the relevant code. A comment should preserve reasoning that would otherwise be lost, rather than repeat the declaration in prose.
Leave the practical dependencies
Record asset locations, entry points, build or upload steps, and any platform behavior that affects the result. Include which checks were completed and what remains uncertain. A handoff that hides limitations creates more work for the next person.
Test a small change
Ask whether someone can replace copy, add a list item, or update a destination without breaking the component. Longer content and a narrow viewport are useful tests. The value of the handoff is visible in the ordinary changes the team will actually make.
This is part of finishing an assignment. Source files, dependencies, and a few decision notes help the receiving team continue the work without needing the original contributor to explain every ordinary change.
The decision: when cleanup would change the behavior
Readable source matters, but an existing workaround may have a reason. In HTML email, nested tables, repeated styles, and unusual spacing can be part of the rendering solution. Before simplifying them, I would establish what they protect and compare the result in the required environments.
For a receiving team, the useful handoff explains the constraint and the checks completed. A cleaner-looking file is not enough evidence that a change is safe.
