class CustomFixer extends SLOS.Fixer.Base {
constructor() {
super();
this.name = ‘custom_fixer’;
this.description = ‘Custom accessibility fixer’;
}

canFix(element) {
// Check if element needs fixing
return element.classList.contains(‘custom-class’);
}

fix(element) {
// Apply the fix
element.setAttribute(‘aria-label’, ‘Custom label’);
return true;
}
}

// Register the fixer
SLOS.Fixer.register(new CustomFixer());
`

// Custom pre-scan logic
}

// After scan completes
addaction(‘slosaccessibilityscancomplete’, ‘custompostscan’, 10, 3);
function custompostscan($scan_id, $results, $options) {
// Custom post-scan processing
}
`

console.log(‘Fixer applied:’, fixer.name);
});
