Sparkline Draw-On-Enter

An analytics card whose trendline draws itself, its area fill wipes in behind, and its end-point dot lands last — the classic SVG line-draw, but with the pathLength trick that removes the getTotalLength() measuring step entirely. Pure CSS, three coordinated animations, and a live crosshair on hover.

Here's a working CSS Animated Card from CodeFronts. Use it as-is or adapt to your framework. All classes are scoped under a unique prefix so the code won't collide with your existing styles. MIT licensed.
Demo: Sparkline Draw-On-Enter
Source: https://codefronts.com/components/css-animated-cards/sparkline-draw-on-enter/

An analytics card whose trendline draws itself, its area fill wipes in behind, and its end-point dot lands last — the classic SVG line-draw, but with the pathLength trick that removes the getTotalLength() measuring step entirely. Pure CSS, three coordinated animations, and a live crosshair on hover.

How this works

The dash trick: set the dash pattern equal to the path length and offset it by the same amount, and the line is invisible. Animate the offset to zero and it draws:

.line { stroke-dasharray: 100; stroke-dashoffset: 100;
        animation: ac-13-draw 1.7s cubic-bezier(.55,0,.2,1) forwards }
@keyframes ac-13-draw { to { stroke-dashoffset: 0 } }

Normally you would have to measure the path with getTotalLength() in JavaScript. The pathLength="100" attribute makes SVG redefine the path's length as 100 user units, so every dash value becomes a percentage and the CSS is portable to any path shape:

<path pathLength="100" d="M0 62 L40 48 …" />   <!-- length is now literally 100 -->

The area fill uses a clip-path: inset(0 100% 0 0) that opens left to right, timed to trail the line by 180 ms — the gradient appears to be poured in behind the stroke. The terminal dot scales in at the end with a spring overshoot, which is the visual full stop.

The hover crosshair is a CSS-only :has() readout: hovering a column highlights its point and reveals the value chip, so the card is genuinely useful rather than merely animated.

Make it yours

  • Draw on scroll: swap forwards for animation-timeline: view(); animation-range: entry 25% cover 55% and the chart draws as it scrolls in.
  • Reverse draw (erase): animate stroke-dashoffset from 0 to -100 to wipe the line away when data changes.
  • Multi-series: give each path its own delay 150 ms apart and lower the opacity of the secondary series — the eye then reads them in order.
  • Comparison ghost: render last period as a dashed grey path with no animation, so the animated line reads as "this period".

Gotchas — read before shipping

  • Without pathLength you must measure the path in JS; a hardcoded dasharray that is too small leaves a visible gap at the end of the draw.
  • stroke-dashoffset animation on very long or complex paths can be expensive — keep sparkline paths under a few dozen points.
  • vector-effect: non-scaling-stroke and pathLength are mutually exclusive. Non-scaling-stroke resolves the dash pattern in screen space, so a stroke-dasharray of 100 stops meaning "the whole path" — the line sits partly drawn at rest and repeats the dash as it animates. Pick one: pathLength for the draw, or non-scaling-stroke for the stroke width.
  • Under preserveAspectRatio="none" the stroke is scaled non-uniformly. Author the viewBox close to the rendered width (here 420 × 96 for a ~418 px card) so the scale factor lands near 1 and the distortion is imperceptible.
  • An SVG chart is invisible to screen readers by default. Provide a <title>, role="img", and ideally a real data table or text summary — this demo ships both.
  • preserveAspectRatio="none" makes sparklines stretch nicely but skews any circles you place on the path; counter-scale the dot or use a separate un-stretched layer.
  • A percentage top positions an element's edge, not its centre — top: 12.5% on a 9 px dot lands it 4.5 px below the data point. Anchor with translate: -50% -50%, and keep it in the translate property rather than a transform, so the landing keyframe's scale does not overwrite it.

Floor set by :has(), oklch(), color-mix() as this demo is written. The core technique itself goes back further — Chrome 80+.

stroke-dasharray/offset animation, pathLength and clip-path inset are Baseline Widely Available. :has() for the hover readout needs Chrome 105 / Safari 15.4 / Firefox 121; without it the chart still draws normally.
