# [[HOWTO CSS Search Button]]

## 🎯 한 줄 통찰 (One-line insight)
`border-left: none;` on the button reuses the EXACT double-border fix already established for adjacent buttons in `[[HOWTO CSS Button Group]]`'s `:not(:last-child)` pattern — here applied to just TWO elements (a text input and a button, both floated and both bordered) sitting flush against each other, where an 80%/20% width split ensures the input dominates visually while the icon button stays compact. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`float: left` on both input and button** — `width: 80%` for the search input, `width: 20%` for the button, summing to 100% — same N-column formula pattern as the layout recipes. [S1]
- **`border-left: none` on the button** — prevents a doubled border where the input's right edge meets the button's left edge, the same principle as the button group's `:not(:last-child)` fix, just applied between two DIFFERENT element types rather than a repeated list of buttons. [S1]
- **`form::after` clearfix** — the standard clearfix, needed because both children are floated. [S1]

## 📖 세부 내용 (Details)
- `form.example input[type=text] { float: left; width: 80%; } form.example button { float: left; width: 20%; border-left: none; } form.example::after { content: ""; clear: both; display: table; }`. [S1]

## ⚖️ 모순 및 업데이트 (Contradictions & updates)
- **버튼 그룹의 이중 테두리 제거 원리가 다른 요소 조합에도 적용됨**: `[[HOWTO CSS Button Group]]`의 `:not(:last-child) { border-right: none; }`이 반복되는 버튼들 사이의 이중 테두리를 막았다면, 이 레시피는 input과 button이라는 서로 다른 두 요소 사이의 접합부에 동일한 원리(`border-left: none`)를 적용한다는 점이 확인됨. [S1]

## 🛠️ 적용 사례 (Applied in summary)
검색어 입력창(80%)과 돋보기 아이콘 버튼(20%)을 이중 테두리 없이 하나로 이어붙인 검색 폼 예제가 원문에서 직접 제시됨. [S1]

## 💻 코드 패턴 (Code patterns)
Search input + button joined without a doubled border (CSS):
```css
form.example input[type=text] { float: left; width: 80%; border: 1px solid grey; }
form.example button { float: left; width: 20%; border: 1px solid grey; border-left: none; }
form.example::after { content: ""; clear: both; display: table; }
```
