Alerts

Alerts give short, contextual feedback: confirmations, warnings, errors and announcements. Pick a colour that matches the meaning, add icons, links or actions, and make them dismissible with a close button and data-bs-dismiss="alert".

1Contextual colours

Eight colour variants to match the meaning of the message.

A primary alert: We listen first, then build a plan around what you actually need.

A secondary alert: Clear prices, honest advice and no surprises along the way.

A success alert: We keep things simple, so you can focus on what matters to you.

A danger alert: Our team has done this many times, so you never have to guess.

A warning alert: Our packaging is plastic-free and every delivery is carbon-neutral.

A info alert: Gift wrapping and a handwritten note are free on every order.

A light alert: Every detail is handled by people who care about getting it right.

A dark alert: Pay securely with card, wallet or in three interest-free instalments.
