This collection is a guide to creating realistic analog clocks using CSS capabilities. It breaks down dial layout via repeating-conic-gradient for precise markers and hand positioning using transform-origin and rotate(). To animate the mechanism, CSS variables passing the current time are employed, or pure @keyframes with steps(60) are used to mimic second-hand “ticking.” These examples demonstrate how to combine geometry and animation to build complex chronometers without heavy graphics.
32 CSS Clocks
Blocky Digital Clock
A voxel-style 3D clock where digits morph physically via CSS transforms driven by sibling selectors, creating a floating, mechanical restructuring effect.
See the Pen Blocky Digital Clock.
CSS Grid Clock (Animated)
A highly detailed Dual Analog Clock component that compares abstract and real-time animation.
See the Pen CSS Grid Clock (Animated).
Digital-Analog Dial Clock
A digital-analog clock hybrid where JavaScript’s setInterval only updates a single CSS variable - --dRotate, while all the complex rotation and counter-rotation of the dials and numbers is handled by pure CSS transform.
See the Pen Digital-Analog Dial Clock.
Blocks Clock with Pixel Art Digits
This retro-style clock leverages CSS Grid for its 3x5 matrix display, dynamically updating the digit structure by manipulating the parent element’s class, while setInterval(setTime, 500) ensures a responsive time refresh.
See the Pen Blocks Clock with Pixel Art Digits.
Neon Clock
A technical showcase demonstrating how to control the neon glow intensity and color scheme using CSS variables and the hsl() function, while delivering a realistic neon tube effect on each digital segment via subtle text-shadow and box-shadow styling.
See the Pen Neon Clock.
