Define input boundaries

While minimalist designs with borderless inputs might appear elegant, they significantly reduce usability for people with diverse needs. Visible input boundaries serve as crucial visual cues that help users identify where to click and type. For people with cognitive disabilities, these borders provide essential structure that reduces confusion and mental effort when completing forms. Users with low vision rely on these boundaries to locate interactive elements quickly without struggling to find where fields begin and end.

Always design form fields with visible outlines or backgrounds that clearly distinguish them from surrounding content. The contrast ratio between the input field and its surroundings should be at least 3:1 to identify the entire clickable area at a glance.^[1]This simple design choice makes forms more accessible while benefiting all users.
