HSL and HSLA colour formats explained
HSL (hsl(h, s%, l%)) describes colour by hue (0–360°), saturation and lightness, which makes it easy to create lighter or darker shades, for example hsl(11, 100%, 60%).
HSLA (hsla(h, s%, l%, a)) is HSL with an added alpha (transparency) value, for example hsla(11, 100%, 60%, 0.5).
Both formats can describe the same colour on screen — they are just different ways of writing it. Different tools and code libraries prefer different formats, which is why converting is so useful.
