HTML5 development services
HTML is the layer that decides whether a page is usable by a screen reader, understood by a search engine and fast on a mid-range phone. We treat it as structure, not as a container for divs.
Where we use HTML5
HTML5 is part of the stack on these 3 services. Each page covers how we work, what you get and what it costs to start.
HTML5 in practice
HTML decides more than people credit it for: whether a screen reader can navigate the page, whether a search engine understands the content, and how fast something appears on a slow connection. Markup that renders without waiting for JavaScript is the single biggest factor in a page feeling instant.
Most accessibility work is simply using the right element. A native button is focusable, keyboard-operable and announced correctly; a div pretending to be one needs a role, a tabindex, key handlers and testing to reach the same place. We use native elements first and reach for ARIA only where the platform genuinely offers nothing.
What we build with HTML5
Landmarks, headings and native controls used correctly, so assistive technology works without a layer of ARIA patches.
Heading hierarchy, metadata and structured data that let search engines read a page the way a person does.
Native validation, correct input types and mobile keyboards that match the field — the details that decide completion rates.
Is HTML5 right for you?
Ask usA good fit when
- Every project — it is the foundation, not an option
- Content and marketing sites where speed and SEO decide performance
- Forms, where native validation and input types raise completion
- Anything with accessibility or public-sector requirements
Probably not when
- Nothing. The only question is how much JavaScript sits on top of it.
What we run alongside HTML5
The rest of the setup, and why each piece is there. We keep this list short on purpose — every dependency is something someone has to maintain.
- Structured data
- Organisation, service, FAQ and breadcrumb schema, where it reflects real content on the page.
- Native form validation
- Correct input types and constraints, which also selects the right mobile keyboard.
- Progressive enhancement
- A page that works before JavaScript arrives, and better afterwards.
- axe DevTools
- Automated accessibility checks in CI, alongside manual keyboard testing.
Why HTML5
Let’s talkAccessibility comes mostly for free
Native elements arrive with keyboard behaviour and screen-reader semantics that custom components have to reimplement.
It is the fastest thing on the page
Markup that renders without waiting for JavaScript is what makes a page feel instant on a slow connection.
It never breaks
Valid HTML written today will render in a decade, which is not true of most of the stack above it.
What we get called in to fix
Get a second opinionDiv soup
Interfaces built entirely from divs and spans, so assistive technology has nothing to work with.
Broken heading order
Headings chosen for size rather than structure, which breaks navigation for screen-reader users.
Inaccessible custom controls
Bespoke dropdowns and modals with no keyboard support — usually replaceable with native elements.
Images without meaningful alt text
Either missing, or filled with filenames, which is worse than nothing.
HTML5 or the alternative
The comparisons we are actually asked to make, answered the way we would answer them on a call.
Native elements first. ARIA is for the gaps, and badly applied ARIA is worse than none.
Server-rendered for content and SEO. Client rendering where the interface is genuinely an application.

Frequently asked questions
Yes — keyboard navigation, screen-reader checks and contrast, as part of QA rather than as an afterthought.
Indirectly but reliably: it drives how content is parsed, how rich results are generated, and how the page performs.
Yes. Organisation, service, FAQ and breadcrumb schema where it reflects real page content.
Yes — keyboard navigation always, and screen-reader passes on the flows that matter, alongside automated checks.
WCAG 2.2 AA as the default target. Where a public-sector or enterprise contract sets a different bar, we work to that.
