# UI Kit

In plain words

A UI kit is a pre-built library of interface components, like buttons, forms, and navigation bars, that designers and developers reuse to build screens more quickly and consistently. UI kits are often built on top of a broader design system.

Example

A designer drags a ready-made card, form and modal from the UI kit to mock up a new feature page in an hour.

    ## How Long Does It Take to Build a Custom Website?

    A well-built custom website typically takes 4 to 8 weeks from kickoff to launch, depending on page count, content readiness, and how many rounds of feedback are involved. Strategy and content usually take longer than the actual design and build. If your team has copy, brand assets, and decision-makers ready to move fast, timelines compress. If content isn't ready, that's almost always what stretches a project past 8 weeks — not the build itself.
