Why Developers Love FlexOS

😓 Other Frameworks 
// Complex setup, confusing classes
<div className="flex flex-col md:flex-row lg:grid 
  lg:grid-cols-2 gap-4 md:gap-6 lg:gap-8 
  p-4 md:p-6 lg:p-8 max-w-full md:max-w-3xl">
  <div className="hidden md:block">
    <Card className="shadow-md hover:shadow-lg
      transition-shadow duration-300">
      {/* More complexity... */}
    </Card>
  </div>
</div>
😊 FlexOS Way 
// Clean, readable, just works
<Grid cols={{ mobile: 1, desktop: 2 }} gap="lg">
  <Hide mobile>
    <Card elevated hover>
      {/* Your content */}
    </Card>
  </Hide>
</Grid>
😓 Centering Content 
/* Which method? Who knows! */
.center {
  display: flex;
  justify-content: center;
  align-items: center;
  /* or maybe... */
  position: absolute;
  top: 50%; left: 50%;
  transform: translate(-50%, -50%);
}
😊 FlexOS Center 
// Just say what you mean
<Center>
  <Text>I'm centered!</Text>
</Center>

// Center in viewport?
<Center viewport>
  <Modal>Perfect!</Modal>
</Center>
