Breakpoints refer to some points in the website design where the style of the page, layout, or section of the site changes. These breakpoints are usually used in responsive websites to show how the elements are displayed on devices like smartphones, tablets, and even desktops.
Breakpoints are very important in website design to make it very user-friendly and accessible to the users on all the devices. When these points are defined and the layout is optimized, the website adapts to various screen sizes, and this improves the user experience across all platforms.
