Lesshat

Lesshat includes over 85 mixins for gradients, flexbox, transforms, animations, and filters, providing a one-stop solution for cross-browser CSS3 as shown in the detailed documentation list.

Mixins generate vendor-prefixed CSS for all major browsers automatically, such as .border-radius outputting -webkit- and -moz- prefixes, eliminating manual prefix work.

Mixins use standard CSS3 property names like .box-shadow instead of arbitrary shortcuts, reducing learning curve and aligning with native CSS syntax per the philosophy section.

Automatically adds units (px, %, deg) when values are omitted, preventing errors in mixins like .border-radius, as highlighted in the tips and tricks.
