CSS Transition Generator — Create Hover Effects Online
Create smooth CSS transitions and hover effects with live preview. Generate copy-ready CSS code for animations and interactive elements. Runs entirely in your browser.
How to Use the Transition Generator
- Select properties — check the CSS properties you want to animate (opacity, transform, background-color, etc.).
- Set duration — use the slider to control how long the transition takes (0-3 seconds).
- Set delay — optionally add a delay before the transition starts.
- Choose timing — select the easing function (ease, linear, ease-in-out, bounce, etc.).
- Adjust hover state — modify opacity, scale, and rotate values for the hover state.
- Preview — hover over the preview box to see the transition in action.
- Copy CSS — grab the generated CSS code with one click.
How It Works
CSS transitions animate the change between two states over a specified duration. When you hover over an element, the browser detects the state change and smoothly interpolates the selected properties from their initial values to the hover values. The transition property tells the browser which CSS properties to animate, how long the animation takes, when it starts, and what curve the animation follows.
The four key properties are: property (what to animate), duration (how long it takes), delay (when it starts), and timing-function (the acceleration curve). You can animate multiple properties independently by listing them in a comma-separated transition shorthand — each with its own duration and easing.
Timing Functions Reference
| Function | Description | Best For |
|---|---|---|
ease | Default — starts slow, accelerates, then decelerates | General-purpose transitions |
linear | Constant speed throughout the animation | Rotations, continuous movements |
ease-in | Starts slowly, then accelerates towards the end | Elements exiting the viewport |
ease-out | Starts fast, then decelerates towards the end | Elements entering the viewport, hover effects |
ease-in-out | Slow at start and end, faster in the middle | Most UI interactions, hover states |
cubic-bezier(x1, y1, x2, y2) | Custom curve using two control points | Bounce, overshoot, or custom easing |
Common Hover Effect Examples
- Button scale-up:
transition: transform 0.2s ease-out;—:hover { transform: scale(1.05); } - Card lift with shadow:
transition: box-shadow 0.3s ease, transform 0.3s ease;—:hover { box-shadow: 0 8px 25px rgba(0,0,0,0.15); transform: translateY(-4px); } - Link underline slide:
transition: background-size 0.3s ease-in-out;—background: linear-gradient(...) no-repeat left bottom; background-size: 0% 2px; :hover { background-size: 100% 2px; } - Icon rotation:
transition: transform 0.4s linear;—:hover { transform: rotate(180deg); } - Color fade:
transition: background-color 0.25s ease, color 0.25s ease;—:hover { background: #3b82f6; color: #fff; }
Browser Support
CSS transitions are supported in all modern browsers including Chrome, Firefox, Safari, and Edge. They were first introduced in 2010 and are now a core part of CSS3. The cubic-bezier() function is also widely supported. For older browsers like Internet Explorer 10 and below, transitions are not supported — the state change will happen instantly without animation. Always consider providing a no-animation fallback for accessibility-sensitive interfaces using the prefers-reduced-motion media query.
Why Use This Transition Generator
CSS transitions bring interfaces to life by smoothly animating property changes. Getting the timing and easing right is crucial for creating natural-feeling interactions. This generator provides instant visual feedback so you can fine-tune your transitions.
The tool generates production-ready CSS that you can copy directly into your stylesheet. By visualizing the hover state, you can ensure your transitions feel responsive and polished before writing any code.
Frequently Asked Questions
Transition requires a trigger (like hover) and animates between two states (initial and final). Animation can run automatically, loop, and have multiple keyframes. Use transitions for simple hover effects; use animations for complex, multi-step sequences.
ease-in-out is the most natural for most UI interactions. ease-out feels responsive for hover effects. linear works for continuous rotations. The cubic-bezier bounce effect is fun but use sparingly — it can feel cartoonish if overused.
List multiple properties in the transition property, separated by commas: transition: opacity 0.3s ease, transform 0.3s ease;. Each property can have its own duration and timing function. The tool generates this automatically when you select multiple properties.
