rené uses semantic colour naming. this means colours are named for their purpose, not their look. so, "error" or "error-red" could be names for colours used in messages.

this makes the stylesheet easier to understand and maintain, and reduces confusion in design.

use 'view' when you want to fill the viewport, giving you control over the visible area.

use '.sticky' to keep elements in view while scrolling, enhancing user navigation.

use '.hidden' to remove elements from the display, managing content visibility without removing them from the document flow.

use '.hidden-on-mobile' to hide certain elements on mobile view, tailoring user experience per device type.

use 'header' for top-level navigation and branding, offering an intuitive user interface.

use 'nav' for main navigation links, directing users across the site.

use 'footer' for secondary information like copyright notices, enhancing site credibility.

use flex-1 when you want to stack items in a specific way, offering flexibility in arranging your content.

use 'hr' to separate sections or elements visually, improving content readability.

rené's animation system provides simple, semantic animation classes. the base .animate class sets default timing, while modifiers let you customize duration, easing, and animation types like fade, slide, or spin.

use .infinite for looping animations. transitions and transforms are also available for hover effects.
