Defining Keyframe Animations for SVG Elements
A @keyframes rule defines a sequence of style states at percentage points through an animation's duration, and applying that animation to an SVG element via the animation CSS property animates supported properties like transform, opacity, and fill smoothly between those defined keyframe states.
- A @keyframes rule defines style states at percentage points through the duration
- The animation property applies a defined keyframe sequence to an SVG element
- Smoothly animates supported properties like transform, opacity, and fill
Animating stroke-dashoffset for Draw-On Effects
Combining a @keyframes rule that animates stroke-dashoffset from a path's full length down to zero with a matching stroke-dasharray value produces the popular draw-on line reveal effect entirely in CSS, without requiring any JavaScript to calculate or trigger the animation manually.
- Animating stroke-dashoffset from full length to zero creates a draw-on effect
- Requires a matching stroke-dasharray value set to the path's total length
- Achieves this popular effect entirely in CSS without any JavaScript involved
Frequently Asked Questions
Can CSS @keyframes alone create a draw-on line animation for SVG?
Yes, animating stroke-dashoffset from the path's full length to zero within a @keyframes rule produces this effect entirely in CSS, without needing JavaScript.
Do all SVG attributes support CSS @keyframes animation?
Not all — CSS keyframes work well for CSS-stylable properties like transform, opacity, and fill, but some SVG-specific attributes may need JavaScript-based animation instead.
