Ember Field

Ember Field is a full-bleed animated gradient background built with CSS alone. Three soft pools of colour, persimmon, saffron and rose-magenta, drift slowly across a deep plum base like a sunset mesh, each on its own long loop so the pattern never quite repeats. A soft bloom rides on the saffron pool, a gentle vignette frames the edges, and a fine film grain keeps the colour from looking like a flat digital fade. There is no JavaScript, no canvas and no image file: the movement comes from registered custom properties that the browser interpolates, so it stays tiny and easy to restyle. It is a single class you can drop onto any section, a hero, a closing call to action or a pricing band, and five variables change the whole mood. A calm light variant is included for brands that want warmth without drama. Text never sits directly on the colour; it lives on a finely lit translucent plate, beside a small variables panel that shows what to change, so contrast holds wherever the light drifts. It suits studios, food and craft brands, event pages and launch sites that want a confident first impression. Visitors who ask their device for reduced motion see a still first frame instead, and everyone gets a pause control.
