Its place among symbols
The warning sign alerts, the check mark confirms, the plus adds; the question mark invites. It is the natural choice for FAQ blocks, quizzes, help buttons and mystery teasers. When a bubble holds both a question and an exclamation mark, it usually illustrates dialogue or feedback.
Choosing a file
For interfaces, pick a clean glyph that survives shrinking to button size. Glossy bubbles and 3D marks fit posters and slide covers better. A heavy colour like red reads as urgent, while blue feels closer to help and information.
