Trigonometric functions in CSS
- Introduction to Trigonometric Functions in CSS
- CSS now supports trigonometric functions such as sin, cos, and tan
- These functions can be used to calculate angles and positions in CSS
- This article demonstrates how to use these functions to draw shapes and position elements
- Drawing Shapes with Trigonometric Functions
- The sin and cos functions can be used to draw lines and shapes
- Example: drawing a triangle using sin and cos to calculate the positions of each point
- Using Inverse Trigonometric Functions
- CSS also supports inverse trigonometric functions such as asin, acos, and atan
- These functions can be used to calculate angles from a given position
- Example: using atan to calculate the angle between two points
- Rotating Elements to Face a Point
- The atan2 function can be used to calculate the relative angle between two points
- This angle can be used to rotate elements so that they face each other
- Example: using atan2 to rotate boxes to face the location of the mouse
