Global classes
Named sets of styles you apply to blocks and reuse, like a button or a card.
A global class is a named set of styles you build once and apply to any block, like a button style, a card, or a section layout. Apply the class wherever it belongs, and a change to the class reaches every block wearing it.
Because you style the class rather than each block, a site stays consistent without the same styles being repeated and re-edited block by block.
Alongside your own classes, external classes let you bring in and apply classes defined outside Slowly.
