Improving Web Accessibility in EstreFlores/svgl

The Challenge

Building powerful UI components often leads to complex DOM structures that can unintentionally hinder accessibility. In the context of the EstreFlores/svgl project, we identified that several elements lacked the necessary semantic markers, making it difficult for assistive technologies to interpret the interface correctly. Accessibility isn't just a checklist; it's about ensuring every user can navigate your application effectively.

The Approach

We focused on three core areas to bring our components up to modern web standards, ensuring that interactive elements are predictable and accessible to all users.

1. Semantic Markup

We moved away from generic container elements and started leveraging native HTML5 tags. By replacing generic divs with appropriate semantic roles, we provide clear context to browser accessibility APIs.

<!-- Before -->
<div on:click={handleAction}>Submit</div>

<!-- After -->
<button type="button" on:click={handleAction}>Submit</button>

2. ARIA Implementation

For custom components where native elements don't quite fit, we implemented ARIA attributes to describe the state and purpose of the elements. For example, ensuring that toggleable icons have an appropriate aria-label or aria-expanded state.

<button 
  aria-label="Toggle menu" 
  aria-expanded={isOpen} 
  on:click={toggle}>
  <Icon />
</button>

3. Keyboard Navigation

We ensured that all custom interactions are reachable via the Tab key and triggerable via the Enter or Space keys. This is critical for users who rely on keyboard navigation rather than a mouse.

Key Takeaways

Accessibility is a continuous process of refinement. To keep your Svelte components accessible, follow these principles:

• Prioritize Native Elements: Use buttons, links, and inputs wherever possible.
• Use Descriptive Labels: Every interactive element needs a clear purpose defined via accessible text.
• Test with Keyboards: If you can't navigate your component with only the Tab and Enter keys, it is not ready for production.

Start by auditing your most-used components today—small improvements in labeling often lead to the biggest gains in user experience.
