flowmanceStartua Design System
Startua (the live site spells the brand Startuā) is an energetic startup and SaaS landing page. It opens on a full deep-violet hero, then switches to calm white sections with black Inter 600 headlines. Hot pink #FF5291 does the shouting: the main buttons, the first word of key headlines and the stats band. Photos are bright lifestyle shots with big 50px corners on one side, bleeding off the page edge.
Four signatures make it recognisable:
- Pink word with a spark. One word of a headline is pink with a small three-stroke spark at its top-right: Supercharge your startup's growth., Simplify lead management with a centralized hub.
- The pink + lavender button pair. A solid pink button (View on Designer, Contact Sales, Get Started) sits next to a lavender #EDEBFF button with violet text and a → arrow (Get Startuā →, Get Started →). Both are 10px radius.
- Violet hero, edge-bleeding photo. The hero is solid #331CD2 with faint looping line art; the photo on the right has 50px corners on its left side only and runs off the right edge of the viewport.
- Comparison table. A plain table (Startuā logo vs Competitors) with 1px black-10% rules, labels left, the Startuā value bold black and the competitor value grey.

Do’s and don’ts
- Open with a full #331CD2 hero and white display-hero (70px, 600, −1px) with one pink #FF5291 word and the spark.
- Pair a pink button (#FF5291, 10px radius, 48px) with a lavender one (#EDEBFF, #331CD2 text, → arrow).
- Keep labels on pink at 16px 600 or larger; white on #FF5291 is about 3.1:1.
- Use 50px corners on the inner side of photos that bleed off the page edge.
- Set paragraphs in #555555, 16px 500, line height 1.3.
- Use 1px black-10% rules for tables and keep surfaces flat.
- Add drop shadows; the template has none.
- Make whole headlines pink or violet on white; colour one word only.
- Invent a lavender hover; none is measured.
- Use #8F8F8F for body text; it is for small meta and nav hover only.
- Round pink or lavender buttons into pills; pills are only for the form fields.
- Mix the brand spellings within one page; pick one (Startuā as on the live logo) and keep it.

DESIGN.mdin your project and mention it in your request, or save it as.cursor/rules/startua.mdc - For the rule file, start it with a front-matter block that sets
alwaysApply: true, so every chat uses it - Ask: “Build a pricing page using DESIGN.md.” Cursor follows the colors, fonts, spacing and rules
- Put
DESIGN.mdin the project root - Add one line to
CLAUDE.md: “Follow DESIGN.md for all UI.” - Ask for any page or component; Claude reads the file first
- Attach
DESIGN.mdto the chat (or paste it in) - Ask: “Build a landing page in this design system.”
- Keep the file in the chat or project knowledge, so follow-up pages stay on style

- Add it to your stylesheet, or in Webflow paste it into Site settings → Custom code inside a
<style>tag - Use the variables anywhere:
