Frequent failures.
DESIGNING THE IDEAL CASE ONLY
No empty, error or overflow states.
USING PLACEHOLDER CONTENT
Real content breaks the layout.
TOO MANY EMPHASISED ELEMENTS
Nothing stands out.
PLACEHOLDER TEXT AS LABELS
Disappears when typing.
LOW CONTRAST FOR STYLE
Unreadable in real conditions.
COLOUR CARRYING MEANING ALONE
Invisible to some users.
ICONS WITHOUT LABELS
Guessed wrongly.
TOO MANY FORM FIELDS
Abandonment.
HIDDEN NAVIGATION ON DESKTOP
Reduces use for no gain.
INCONSISTENT COMPONENTS
Re-learning on every screen.
NO FOCUS INDICATOR
Unusable by keyboard.
IGNORING MOBILE UNTIL LAST
Where most visitors are.
SHIPPING WITHOUT WATCHING ANYONE USE IT
The largest mistake of all.
WHAT PREVENTS MOST OF THESE
Real content, real devices, real people.
