User experience covers how people feel and succeed when using a product. For frontend developers, that means: clear hierarchy and labels, predictable behavior, helpful feedback (loading, success, errors), and reducing friction in key flows.

UX is not only visual design; it includes information architecture, copy, performance, and accessibility. Small details (button placement, error messages) have a big impact.

Users should quickly see what the page is for and what they can do. Use clear headings, visible primary actions, and a logical reading order. Avoid clutter; leave white space so important elements stand out.

Information hierarchy (size, color, position) guides the eye. Make the most important thing the most obvious. Forms: group related fields, label everything, and show validation where the user is looking.

Users need to know that an action worked or failed. Use loading states, success messages, and clear error text. Disable buttons during submit to prevent double submission.

Consistent patterns (e.g. primary action on the right, same icon for “close”) reduce cognitive load. Follow platform conventions (web or native) unless you have a strong reason to diverge.

Observe real users when you can; use analytics and support feedback to find pain points. Iterate on the riskiest or most-used flows first. Collaborate with designers and product so frontend choices support the overall experience.
