Style & Animate is a visual styles editor and keyframe animator for WordPress.
The front-end editor makes it easy to change or add styles on any page or post, apply styles and animations on single pages or across the whole site, and build animations and transition effects quickly by setting styles on individual keyframes.
Style and Animate produces pure CSS, it does not use JavaScript to change the site appearance. Style and Animate was developed specifically not to use JavaScript to create style changes in the web site, so all styling is done in a single CSS style sheet. This keeps bloat down and the site runs as if the new styles and animations are part of the theme, not added on afterwards in script – so there is no extra JavaScript to slow the site down.
