Breakpoints are used with @media queries. @media() specifies a rule to include a block of CSS properties only if a certain condition is true.

Within the media query () you specify a condition. For example, you want the background color of a screen to change depending on how big the screen window is. You might have one size for a cellphone window, one for a tablet, etc. Each condition is called a breakpoint. For the code below, the font size will change only if screen width is at least 360px wide.

@media (min-width: 360px) { body { font-size: 1.0em; } }
