Repair Hand-Written HTML and CSS on an Older Website in La Belle

An older hand-coded website does not need replacement merely because its HTML or CSS is old.

The first job is to identify the smallest broken layer.

Separate markup, style, assets, and server problems

A visual failure can come from several sources.

Check whether the problem is caused by:

• invalid or brittle HTML;
• CSS rules;
• missing images or fonts;
• browser compatibility;
• broken paths;
• server configuration;
• a changed external dependency.

Repairing the wrong layer can create more work than the original problem.

Preserve working pages and URLs

If the content and public routes still serve the business, keep them where practical.

A layout problem should not automatically trigger URL changes, content rewrites, or a platform migration.

Preserving stable paths also reduces migration risk.

Repair brittle layout code selectively

Older layouts may use fixed widths, floats, table-based structure, or CSS assumptions that no longer behave well on current screens.

The repair can modernize the affected section without rewriting unrelated pages.

Where useful, shared styles can be consolidated so the same bug does not need to be fixed repeatedly.

Add responsive behavior carefully

Mobile improvements should preserve the site's content and information hierarchy.

Navigation, images, forms, and readable line lengths matter more than making every old page visually fashionable.

Test the changed layout at several widths and on real or emulated mobile devices.

Improve semantics where it helps

If markup is being touched anyway, obvious problems such as missing headings, improper links, unlabeled forms, or generic clickable elements can be corrected.

Semantic cleanup should support accessibility and maintainability rather than become an excuse for a complete rewrite.

Document remaining legacy limits

Some old sites will still contain constraints that are not worth removing immediately.

Record those limits so future maintenance is based on known tradeoffs rather than rediscovery.

Test representative pages before applying global changes

Hand-coded sites often contain years of small exceptions.

A CSS rule that repairs one page can unexpectedly damage another if both rely on old shared selectors.

Before changing global styles, identify representative page types and test the repair across each one.

That may include the home page, service pages, forms, image-heavy pages, and any unusual layouts.

Where old styles are tightly coupled, a narrow new class or component can be safer than rewriting the whole stylesheet at once.

This keeps targeted repair truly targeted and reduces the chance that a small modernization creates new regressions elsewhere.
