Understanding CSS Breakpoints in Responsive Design
A breakpoint in CSS is a specific viewport width (or sometimes height) at which the layout of a webpage changes to provide an optimal viewing experience on different devices. Breakpoints are defined using media queries to apply different styles depending on the screen size.
Why Breakpoints Are Used
- To ensure the layout adapts seamlessly across mobile, tablet, and desktop devices.
 - To enhance readability and usability on varying screen sizes.
 - To optimize performance by loading appropriate styles only when needed.
 - To create a fluid, responsive design that maintains visual consistency.
