/* -- Surface ----------------------------------------------------------------- An endlessly repeating texture in CSS alone: a seamless tile (an SVG or a gradient used as a mask) paints the surface's ink, a second tile its accent. data-pattern picks the tile, data-style the look (25 styles), data-motion how it moves (23 motions) and data-projection the plane it lies on (22 projections). The texture sits on two pseudo-elements behind the content, so a surface holds any markup. The plane: each pseudo-element is a square centered on a pivot. A projection tips it in 3D about that pivot (perspective() puts the eye there) and moves its center along the plane to the point it turns about. The square is large enough that any turn about its center still covers the visible area, so rotation never shows a gap; a receding plane fades out before its edge - a linear fade measured from the center (it stays a straight horizon), or a radial one while the plane spins (it is the same at every angle). Every motion moves the transform (or the opacity), never the mask, so nothing is repainted while it runs. Variants: block (default; empty, it takes --surface-aspect) and background (fills its parent behind the parent's content). */ /* the tile's offset: a receding plane drifts by moving its tile, not itself, so its fade stays where it is */ @property --_mx { syntax: "";
