Neo-brutalism is a bold visual style that uses simple shapes, strong outlines, bright colors, and a deliberately rough or playful look. On a website, it may make buttons and cards feel like cut-out paper pieces.
The style can help a page feel energetic and stand out from polished, glossy designs. But strong colors and heavy borders can also compete with the words and actions people need to find.
Use the bold look where it supports the message, and check that text remains readable and buttons still look usable.
