Isometric Diner Switch
Live Preview
A sophisticated 3D isometric toggle component that reimagines the food-switching concept. It utilizes CSS transform-style: preserve-3d to create a tangible, block-based interface. The knob is a rendered cuboid that slides across a recessed platform, toggling between an isometric burger stack and a 3D fry box. The design prioritizes depth and spatial awareness through careful use of Z-axis translations and lighting-inspired color shading.

Frequently Asked Questions
How does the Isometric Diner Switch simulate depth and directional lighting on the cuboid knob without using external textures?
The component utilizes CSS transform-style: preserve-3d on the knob container, with individual faces defined by absolute-positioned divs. Lighting is simulated by applying varying brightness levels to the background-color of each face—typically the top face is lightest, the front face is neutral, and the side face uses a darker shade or a linear-gradient—to mimic a fixed-position light source relative to the isometric grid.
Which CSS selectors and properties are used to implement the 'Zero-JavaScript' toggle functionality?
The component employs the 'checkbox hack,' utilizing a hidden checkbox input paired with the :checked pseudo-class and the general sibling combinator (~). When the input state changes, the selector input:checked ~ .switch-track .knob triggers a transform: translateX() move, shifting the 3D cuboid from the burger position to the fry box position based entirely on the DOM state.
How is the 'spring-like' physical momentum achieved during the transition between the two food states?
The motion is defined by a CSS transition property using a custom cubic-bezier(0.68, -0.55, 0.265, 1.55) timing function. This specific curve creates an 'anticipation' and 'overshoot' effect, where the cuboid slightly reverses before sliding and then bounces past its destination coordinates, giving the 3D block a sense of weight and physical elasticity.
What specific transformation strategy allows the hover state to shift the user's perspective without breaking the isometric alignment?
The component wraps the switch in a perspective-container that applies a fixed perspective (e.g., 1000px). Upon :hover, a subtle adjustment is made to the transform: rotateX() and rotateY() values of the parent wrapper. Because the child elements inherit the 3D space, this slightly tilts the entire scene, revealing more of the cuboid's Z-axis depth and the recessed track's side-walls without deforming the 2:1 isometric ratio.
How would you adapt the component's internal Z-index management to accommodate a third food item, such as a 3D soda cup, in a multi-state configuration?
To add a third state, the checkbox must be replaced with radio buttons and the track width increased by 50%. Each food asset (burger, fries, soda) must be wrapped in its own container with transform: translateZ() values to ensure that as the knob slides, the assets remain vertically distinct. The CSS would use input[value='soda']:checked ~ .track .knob to calculate the precise translateX percentage required to align the cuboid with the third isometric asset.
