Slide Animations move elements into or out of view along an axis (left, right, up, down). Provides clear direction and spatial context. Common for drawers, mobile menus, sheets, carousels. Direction matters—slide from right for "next," from left for "back." Usually combined with fade for smooth appearance.
Use slide for spatial transitions: drawers (slide from side), mobile sheets (slide up from bottom), page transitions (slide left/right for navigation), carousels, sidebars. Direction should match mental model: next/forward = left, back = right, more detail = up, dismiss = down. Combine with fade (fade + slide). Duration: 250-400ms. Use transform (translateX/Y) for performance.
