Ensure easily readable text on website against its background colours

Comfortably access and engage with the content without straining my eyes, regardless of my visual abilities 
All text on buttons, backgrounds, and other UI elements must have a contrast ratio of at least 4.5:1 for normal text (font size < 18pt or 24px) and 3:1 for large text (font size ≥ 18pt or 24px), as per WCAG 2.1 Success Criterion 1.4.3.

For users with colour blindness or low vision, non-colour cues (e.g., underlines for links, borders for buttons) must be present to distinguish interactive elements.

Screen reader users must receive accurate descriptions of UI elements (e.g., buttons labeled with descriptive text via alt attributes).
