Madox Startup Template Design System
Madox is a tidy, product-like startup UI kit. It is white and pale grey-blue (#F4F5F8), set in heavy Inter, with one strong orange (#FF8500) and hard square corners on every button, card and field. A handwritten Caveat script adds a human note: little scrawled labels and curly arrows that point at buttons.
Four signatures make it recognisable:
- Zero radius. Buttons, cards, thumbnails and inputs are all sharp rectangles. Only avatars are round.
- Handwritten asides. Caveat script with a hand-drawn arrow sits beside the main buttons (Only $79 on marketplace), after the logo (Ui Kit Template in orange) and under every showcase card (Home 1, About 2, Pricing).
- Orange with black text. The main button is #FF8500 with black 16px bold text, beside a solid black Buy Madox button. On hover every button turns black with white text.
- The page showcase grid. The home page is a presentation: a 3-column grid of #F4F5F8 cards, each framing a white page thumbnail with a soft 0 8px 25px 5% shadow, captioned in Caveat.

Do’s and don’ts
- Keep every button, card, image and field at 0px radius.
- Use #FF8500 for the main button with black 16px bold text, and turn all buttons #000000 with white text on hover.
- Alternate #FFFFFF and #F4F5F8 bands; put white content cards on the grey with the 0 8px 25px #0000000D shadow.
- Set headlines in Inter 700 at tight line height (0.92 for the hero) and paragraphs in Inter 600 #6E6E6E.
- Add one Caveat hand note with a drawn arrow next to the main call to action.
- Use orange sentence-case eyebrows (17px, 600) above headings.
- Put white text on #FF8500; use black (8.61:1). Orange text on white is 2.44:1, so keep orange text to 17px+ eyebrows, the active nav link and short captions.
- Use ink-subtle (#111111 at 61%) for anything but 16px bold dropdown links; it is 5.17:1 on white and reserved for menus.
- Round corners or add pill shapes; only avatars are circles.
- Use Caveat for anything longer than a short note or caption.
- Add a second accent colour or gradients.
- Use heavy shadows; the template's only shadow is 5% black.
