Frequently Asked Questions
How do I make a rounded card border?
Set 1–2px solid with your brand color plus 12–16px radius: the classic card look. The preview updates live — copy the shorthand straight into your stylesheet.
Which border styles exist?
Solid, dashed, dotted, double, groove, and ridge — all six render in preview. Dashed suits coupons and tickets; double frames certificates.
Can I style each side differently?
No — one width, style, color, and radius apply to the whole box (e.g. 1–2px solid plus 12–16px radius for cards). Per-side accent bars need hand-written longhand.
Is anything sent to a server?
No — generation runs locally in your browser. Copy the CSS free with no account.
