Semantic HTML5 development
The layer everything else sits on. Get it right and accessibility and SEO largely follow; get it wrong and no framework rescues it.
Markup
Chosen per project
Maintainable handover
HTML is the part of a website most often treated as a formality — a bag of divs to hang styling from. That is precisely why so many sites are hard to navigate with a keyboard and thin in search results despite having good content.
Semantic markup costs nothing extra to write. A heading that is a real heading, a button that is a real button, a landmark that names a region of the page — these give assistive technology a document it can navigate and give crawlers a structure they can interpret.
What we build with HTML5
Marketing sites that need to rank on their content
Any product with an accessibility requirement or public-sector buyer
Documents and forms that must work without JavaScript
Rebuilding a site whose markup has become unmaintainable
Where it fits — and where it does not
Good fit when
Content that must be indexed and understood
Products with accessibility obligations
Long-lived pages where markup outlives the styling
Forms where native controls beat custom widgets
Consider something else when
Highly interactive application interfaces still need a framework on top
Canvas or WebGL-driven experiences sit outside document semantics
What semantic markup gives you for free
Each layer of a well-formed document serves both a human reader and a machine one. None of it requires extra code — only the correct element.
Landmarks
header, nav, main, footer — navigable regions.
Heading outline
One H1, no skipped levels, a real table of contents.
Native controls
Buttons and inputs that work with a keyboard by default.
Alternative text
Meaning conveyed when images cannot be seen.
Structured data
Machine-readable meaning layered on top.
How we work with HTML5
Landmarks first
Header, nav, main, aside and footer defined before any visual work, so the page has a navigable skeleton.
One H1, ordered headings
A heading outline that never skips a level, because that outline is how screen readers navigate.
Native controls
Real buttons, real inputs, real labels — custom widgets only where nothing native exists.
Validation
Markup checked for duplicate IDs, unlabelled controls and missing alternative text as part of the build.
Our typical HTML5 setup
| Concern | What we use |
|---|---|
| Standard | HTML Living Standard, validated in the build |
| Accessibility | WAI-ARIA only where native semantics fall short |
| Structured data | JSON-LD for organisation, breadcrumb, FAQ and article |
| Forms | Native inputs with explicit labels and inline error messaging |
| Testing | Automated checks plus keyboard and screen-reader passes |
Frequently asked questions
Indirectly but meaningfully. It does not add a ranking bonus on its own, but it determines whether a crawler can identify your headings, navigation and main content — and it underpins structured data, which does drive rich results.
For a brochure site or a document, often yes. Once users need to work inside the page — filtering, multi-step forms, live data — you need JavaScript, but it should enhance sound markup rather than replace it.
Usually, and it is frequently better value than a rebuild. An audit identifies the heading structure, landmark and labelling problems, most of which are correctable without touching the design.

Website Development
A website is usually the first thing a prospective customer sees. It should load quickly, say something useful and be findable.
UI/UX Design
Interfaces designed around what people are trying to accomplish, then tested with them before development starts.
CMS Development
Publishing tools shaped to your content, so the people who write it can ship it without a developer.
Web Application Development
Applications that run in the browser, handle real workloads and hold up when several departments depend on them at once.
