Web accessibility is about enabling more people to perceive content, navigate a website, use interactive controls, complete forms and perform important tasks without unnecessary barriers.
Accessibility optimization is not a toolbar or plugin that automatically fixes an entire website. Many accessibility problems are found in the HTML structure, templates, menus, forms, colours, components and the way the content itself has been organized.
A practical review based on WCAG principles
We use the Web Content Accessibility Guidelines (WCAG) as a technical reference for identifying and prioritizing accessibility improvements. A review can cover content structure, navigation, keyboard interaction, focus, contrast, forms, images and interactive components.
The objective is to identify specific barriers and provide practical remediation. We do not present an automated scan or a single technical change as a guarantee that every accessibility requirement or legal obligation has been satisfied.
What we can review and improve
- Heading structure and semantic HTML so content has a logical hierarchy.
- Keyboard navigation for menus, links, buttons, forms and other functional controls.
- Focus states so keyboard users can see which element is currently active.
- Colour contrast and text readability for important content and interface elements.
- Alt text and text alternatives for images that communicate information.
- Labels, instructions and error messages in forms.
- Links and buttons with understandable purpose and appropriate behaviour.
- Skip links and navigation landmarks where useful.
- ARIA attributes when genuinely required and where native HTML does not provide the appropriate solution.
- Joomla and PrestaShop templates or modules that create navigation or interaction barriers.
Semantic HTML and content structure
Correct use of headings, lists, buttons, links, labels and other HTML elements gives content a meaningful structure. An interface may look understandable visually while still being difficult to interpret through assistive technologies if generic elements are used in place of the appropriate semantic controls.
During review, we look for opportunities to improve the structure using suitable native HTML before adding more complex ARIA solutions.
Keyboard navigation
Important website functions should not depend exclusively on a mouse. Menus, links, buttons, modal components, forms and other interactive controls are reviewed for keyboard access problems.
Particular attention is given to keyboard traps, where focus can enter a component but cannot leave it through normal keyboard interaction.
Visible focus that is not obscured
People navigating with Tab or other keyboard input need to understand which control is active. We review whether focus indicators are visible and whether sticky headers, banners, overlays or other author-created elements hide the focused component.
This is particularly important in menus, forms, buttons and interfaces with sequential keyboard navigation.
Colour, contrast and readability
Text and important interface elements need sufficient distinction from their background, and information should not depend on colour alone. We review contrast problems and cases where status, errors or selection are communicated only through a colour change.
Images and text alternatives
Images that communicate information need an appropriate text alternative. Alt text should not be filled mechanically with keywords and should not repeat surrounding text without a reason. It should serve the actual purpose of the image.
Purely decorative images are treated differently from product images, diagrams, icons or other graphics that communicate meaningful information.
Forms that explain what users need to do
Contact forms, login forms, checkout flows and other input interfaces are common sources of accessibility barriers. We review the relationship between labels and fields, instructions, required inputs, error messages and keyboard interaction.
An error message should help the user understand which field needs attention rather than provide only a generic failure message.
Accessibility in Joomla
In Joomla, the final accessibility of a website is influenced by the template, modules, menu components, forms and the way content is authored. A review can identify whether a problem originates in Joomla content, the template or a particular extension.
For new projects, accessibility is more effective when it is considered from the beginning of web design and development rather than treated only as a remediation task after the site has been completed.
Accessibility in PrestaShop
For a PrestaShop e-commerce store, review needs to extend beyond static pages to product listings, filters, product pages, cart, checkout, account forms and modules that introduce interactive functionality.
An accessibility toolbar may provide certain assistance options, but it does not replace fixing structural and interaction problems in the store itself.
Automated checks and manual testing
Automated tools are useful for identifying certain technical issues, but they cannot evaluate every part of the user experience correctly. For example, a tool may detect a missing alt attribute but cannot always determine whether the text that has been provided accurately communicates the purpose of the image.
A practical accessibility review therefore combines automated findings with manual examination of important user journeys and interactive controls.
Prioritizing remediation
An existing site may produce many findings, but not every issue has the same impact. Priority is given to barriers that block important navigation or tasks, such as menus or checkout flows that cannot be used with a keyboard, unclear forms or important content that cannot be perceived correctly.
Accessibility is an ongoing process
Websites change as new content, modules, templates and features are introduced. Accessibility therefore needs to be considered during future changes as well. A problem fixed today can be reintroduced later by a new component or redesign.
How an accessibility engagement starts
We begin by reviewing the existing website and its important user journeys. Issues, likely sources and remediation priorities are documented. Changes can then be applied to content, templates or components where technically possible.
The purpose of the service is to improve real accessibility rather than produce only a generic score or a “compliance” badge without technical evidence.
