Saas Productivitydylantarre/animation-principlesUse when designing animations for business tools, project management, collaboration software, or productivity apps01 Scroll Animationsdylantarre/animation-principlesUse when triggering animations on scroll - reveal effects, parallax, sticky headers, progress indicators, or any scroll-linked motion.01 Secondary Action Masterydylantarre/animation-principlesUse when enriching primary animations, adding supporting details, creating depth in motion, or making scenes feel alive without distracting from main action.01 Slow 800 1200msdylantarre/animation-principlesUse when building deliberate motion between 800-1200ms - dramatic reveals, loading sequences, storytelling moments where users should pause and absorb01 Slow In Out Masterydylantarre/animation-principlesUse when designing easing curves, controlling motion pacing, creating natural acceleration/deceleration, or making movements feel physically grounded.01 Small 200 300msdylantarre/animation-principlesUse when building small transitions between 200-300ms - modal appearances, card expansions, navigation transitions that users consciously perceive01 Social Mediadylantarre/animation-principlesUse when designing animations for social platforms, messaging apps, content sharing, or community features01 Solid Drawing Masterydylantarre/animation-principlesUse when creating motion that needs dimensional grounding, designing transforms that maintain object integrity, or ensuring animations feel structurally sound.01 Spatial Thinkingdylantarre/animation-principlesUse when animation involves depth, perspective, volume, or three-dimensional awareness—camera moves, character positioning, environmental interaction, or maintaining consistent spatial relationships.01 Squash Stretch Masterydylantarre/animation-principlesUse when implementing deformation effects, bounce animations, impact responses, or any motion requiring organic elasticity and weight expression.01 Staging Masterydylantarre/animation-principlesUse when composing scenes, designing layouts, directing user attention, or ensuring a single clear idea is communicated at any given moment.01 State Changesdylantarre/animation-principlesUse when elements transform in place - toggle switches, expanding accordions, checkbox animations, button states, or any transformation without entering/exiting.01 Straight Ahead Pose Masterydylantarre/animation-principlesUse when planning animation workflows, deciding between spontaneous vs controlled approaches, or balancing creative freedom with structural precision.01 Technical Constraintsdylantarre/animation-principlesUse when animation is limited by browser support, platform capabilities, or technical requirements01 Timing Calibrationdylantarre/animation-principlesUse when animation speed feels wrong—too fast, too slow, or inconsistent01 Timing Masterydylantarre/animation-principlesUse when determining how fast or slow motion should be—pacing action sequences, dramatic pauses, comedic beats, or any situation where the duration of movement matters.01 Timing Principle Masterydylantarre/animation-principlesUse when determining animation durations, controlling pacing, establishing rhythm, or making motion feel appropriately weighted and emotionally resonant.01 Transition Sequencesdylantarre/animation-principlesUse when orchestrating multi-step animations - page transitions, onboarding flows, wizard steps, complex reveals, or any choreographed animation sequence.01 Travel Hospitalitydylantarre/animation-principlesUse when designing animations for travel booking, hospitality apps, tourism platforms, or vacation planning experiences01 Trust Reliabilitydylantarre/animation-principlesUse when creating animations that build user confidence, establish credibility, and communicate dependability.01 Universal Elementsdylantarre/animation-principlesUse when animating any UI element not covered by specific skills, or when applying general animation principles across multiple element types01 Universal Emotiondylantarre/animation-principlesUse when you need to achieve any emotional outcome through animation—provides a framework for mapping Disney principles to any target emotion.01 Universal Fallbackdylantarre/animation-principlesUse when the animation domain is unclear or spans multiple contexts—provides general-purpose Disney animation principle guidance.01 Universal Industrydylantarre/animation-principlesUse when designing animations for any industry or when industry-specific guidelines do not apply01 Universal Mindsetdylantarre/animation-principlesUse when approaching any animation task—establishing foundational thinking patterns, teaching animation principles, or when none of the specialized thinking styles quite fit the situation.01 Universal Patternsdylantarre/animation-principlesUse when creating any animation type - provides foundational timing, easing, and principle application that applies to all motion in interfaces.01 Universal Practitionerdylantarre/animation-principlesUse when applying animation principles in any context, for any role, or when a general understanding of Disney's 12 principles is needed.01 Universal Solutionsdylantarre/animation-principlesUse when facing any animation problem as a comprehensive diagnostic framework01 Universal Timingdylantarre/animation-principlesUse when learning animation timing fundamentals - principles that apply regardless of duration, the foundational rules that scale across all time ranges01 Universal Tooldylantarre/animation-principlesUse when implementing Disney's 12 animation principles with any animation tool or framework01 Urgency Actiondylantarre/animation-principlesUse when creating animations that prompt immediate user action, highlight time-sensitivity, or drive conversions.01 User Feedback Claritydylantarre/animation-principlesUse when users don't notice feedback, miss state changes, or can't tell if their action worked01 UX Frictiondylantarre/animation-principlesUse when animation causes user confusion, delays task completion, or creates frustration01 UX Researcherdylantarre/animation-principlesUse when evaluating animation usability, conducting motion studies, or when researching how animation affects user perception and task completion.01 Video Motion Graphicsdylantarre/animation-principlesUse when creating After Effects compositions, Premiere Pro motion, video titles, explainer videos, or broadcast motion graphics.01 Web Motion Designdylantarre/animation-principlesUse when building CSS animations, JavaScript transitions, React/Vue motion, or any browser-based animation work.01
