Building a Accessibility Plugin for WordPress
Accessibility Helper is a WordPress plugin designed to make your website more accessible for everyone. It provides an easy-to-use panel that lets visitors adjust font size, switch to a dyslexia-friendly font, hear image descriptions read aloud, and apply color schemes for common types of color blindness — all with customisable colors and styles to match your site’s branding.
How does the Accessibility Plugin work
– The plugin wraps your page content in a container that scales with the font size controls.
– The panel is positioned in one of four corners based on your admin settings.
– The dyslexic font is loaded via CDN when toggled.
– For screen readers and visual aid, the alt text reader uses `speechSynthesis` to speak out image descriptions on hover.
– Color blind schemes are applied using the different sliders that adapt your theme for color blindness.
– There is a color contrast validation to ensure that there are no contrasting colors whilst customising the plugin between the background color, button color and text color.
– First time load up, a notification pops up that mentions about using keyboard shortcode to access panel.
