Assess your grasp on animating SVG graphics using GSAP, exploring key techniques, animation sequencing, timing controls, and best practices for dynamic web graphics. This quiz helps reinforce fundamental principles and common pitfalls when working with scalable vector graphics and advanced animation timelines.
Which of the following is the correct way to target a circle element with the id 'dot' in an SVG for animation using GSAP selectors?
Explanation: The correct selector to target a circle element with the id of 'dot' is '#dot', matching standard selector syntax. '.dot' would target a class rather than an id and would not work unless you assign a class. 'svg#dot' targets an SVG element rather than a nested circle. 'circle-dot' is not a valid selector in standard use.
If you want to animate the SVG attribute 'stroke-dashoffset' to create a drawing effect, which GSAP property should you use inside the tween configuration?
Explanation: GSAP uses camelCase versions of SVG attribute names in its configuration objects, so 'strokeDashoffset' is correct. 'strokeoffset' is not an actual property and would be ignored. 'strokeDashOffset' is incorrect because the 'O' should be lowercase per GSAP conventions. 'stroke-dashoffset' would work as a string in some cases, but camelCase is preferred and more reliable within GSAP.
Suppose you have several SVG rectangles each with the class 'bar', and you want them to scale up one after another. Which GSAP feature allows you to delay the start of each rectangle's animation for a cascading effect?
Explanation: The 'stagger' property instructs GSAP to initiate each element's animation with a controlled delay for effects like cascades or ripples. 'repeat' sets how many times an animation runs but does not affect the start time between elements. 'loop' isn't a GSAP property and would not provide the cascading effect. 'timeline' organizes sequences but doesn't inherently delay each element unless staggered.
When animating an SVG path to mimic a natural motion such as a bouncing ball, which GSAP property should you adjust to control the acceleration and deceleration of the animation?
Explanation: 'ease' determines the rate of change during the animation, helping you create effects like bounce, elastic, or gradual acceleration. 'duration' only sets how long the animation takes, not the speed curve. 'direction' is not a direct GSAP tween property for SVG movement. 'yoyo' controls whether an animation reverses after completion, but not its speed profile.
Imagine you need to coordinate several SVG elements moving in sequence—a line draws, a circle appears, then a rectangle fades in. Which GSAP feature allows you to organize these animations with precise timing control?
Explanation: A timeline enables you to chain multiple animations together, each starting at precise times or after previous animations complete, ideal for orchestrated sequences. 'callback' is a function that executes at certain animation points, not for managing multiple sequential animations. 'batch' refers to grouping but not timeline management. 'delay' applies a fixed wait time but cannot organize a series of events efficiently like a timeline can.
