Hero Section CSS Search Bar with CTA

A landing-page hero built around search: an oversized field with a solid CTA fused to its right edge, a fluid headline above and popular-query chips below. Everything scales with clamp(), and the CTA drops under the field on narrow screens without a media-query pile-up.

```

How this works

Fluid, not stepped. A hero is the one place where clamp() earns its keep. The headline, the field height and the padding all interpolate between a mobile and a desktop value with no breakpoint:

.sb-23__h1{font-size:clamp(1.9rem, 1.2rem + 3.4vw, 3.4rem); text-wrap:balance;}
.sb-23__bar{min-block-size:clamp(56px, 4vw + 44px, 68px);}

Wrapping the CTA without a media query. The bar is flex-wrap:wrap; the input has flex:1 1 16rem. When the container drops below roughly 16rem + button width, the button wraps to its own full-width row — one declaration instead of a breakpoint.

.sb-23__input{flex:1 1 16rem;}
.sb-23__cta{flex:1 1 auto;}   /* full width once it wraps */

Popular chips do real work. They are the highest-converting element in a search hero: they teach users what the corpus contains. Keep them to 3-5, make them buttons, and give them 44px targets.

Make it yours

  • Change the hero copy and chips to your top three real queries — pulled from analytics, not invented.
  • For a dark hero, flip --bg and --card and keep the CTA accent; the layout is unchanged.
  • Add a category select in the bar (see demo #03) if your catalogue needs scoping; the flex layout accommodates it.
  • Tighten to a single-column stack by setting .sb-23__bar{flex-direction:column} — the CTA then always sits below.

Gotchas — read before shipping

  • A hero input under 56px tall looks weak at desktop sizes; a hero input over 72px looks like a mistake. Clamp between the two.
  • Do not centre-align long chip rows and body copy with text-align:center alone — use flex centring so wrapped rows stay even.
  • Placeholder text is not a value proposition. Keep the promise in the headline, where screen readers and search engines can index it.
  • Watch the CTA's contrast on a gradient background — this demo keeps the button on a solid fill for exactly that reason.

Browser support

text-wrap: balance is Chrome 114 / Safari 17.5 / Firefox 121 and degrades to normal wrapping. clamp() and flex-wrap are baseline everywhere. No JavaScript is used.
