Question 5 of 104
How does the universal selector (*) work and when should you use it?
← All CSS3 questions
Re-explain
The universal selector * matches all elements. Common uses:
/* Reset all margins and padding */
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
/* Target all children */
.container * {
font-family: Arial, sans-serif;
}
Use sparingly as it can impact performance and may override more specific styles unintentionally.
