# [[CSS Styling Buttons]]

## 🎯 한 줄 통찰 (One-line insight)
Buttons can be created from `<button>`, `<input type="button">`, or styled `<a>` elements, and CSS properties like `background-color`, `padding`, `border-radius`, and `border` give them their visual style. [S1]

## 🧠 핵심 개념 (Core concepts)
- **Multiple sources** — buttons can be created using `<button>`, `<input type="button">`, or styled `<a>` elements. [S1]
- **Core styling properties** — `background-color`, `color`, `border`, `padding`, `border-radius`, `text-align`, `font-size`, `text-decoration`, and `cursor`. [S1]
- **Color variety** — different `background-color` values (green, blue, red, gray, black) distinguish button purposes. [S1]
- **Sizing** — `font-size` adjusts text size; `padding` controls spacing around the text. [S1]
- **Rounding** — `border-radius` rounds corners, up to `50%` for a circular effect. [S1]
- **Borders** — `border` can be solid, dotted, or dashed in various colors. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Base button class** — define a `.button` class with background, no border, white text, padding, centered text, no underline, `inline-block` display, font size, and a pointer cursor. [S1]
- **Variant classes** — layer numbered classes (`.button1`…`.button5`) over the base to vary color, size, rounding, or border. [S1]

## 📖 세부 내용 (Details)
**Basic button styling** — a basic button styling for different HTML elements. [S1]
```css
.button {
  background-color: red;
  border: none;
  color: white;
  padding: 15px 32px;
  text-align: center;
  text-decoration: none;
  display: inline-block;
  font-size: 16px;
  cursor: pointer;
}
```

**Button colors** — buttons with different colors. [S1]
```css
.button1 {background-color: #04AA6D;} /* Green */
.button2 {background-color: #008CBA;} /* Blue */
.button3 {background-color: #f44336;} /* Red */
.button4 {background-color: #e7e7e7; color: black;} /* Gray */
.button5 {background-color: #555555;} /* Black */
```

**Button sizes** — buttons with different font size. [S1]
```css
.button1 {font-size: 10px;}
.button2 {font-size: 12px;}
.button3 {font-size: 16px;}
.button4 {font-size: 20px;}
.button5 {font-size: 24px;}
```

**Rounded buttons** — `border-radius` adds rounded corners, up to `50%`. [S1]
```css
.button1 {border-radius: 2px;}
.button2 {border-radius: 4px;}
.button3 {border-radius: 8px;}
.button4 {border-radius: 12px;}
.button5 {border-radius: 50%;}
```

**Colored button borders** — borders can be solid, dotted, or dashed in various colors. (Per the source, only the `border` property is specified for each class; no `background-color`/`color` in these particular examples.) [S1]
```css
.button1 {border: 2px solid #04AA6D;}
.button2 {border: 2px dotted #008CBA;}
.button3 {border: 2px dashed #f44336;}
.button4 {border: 1px solid #e7e7e7;}
.button5 {border: 1px solid #555555;}
```

**Note on further sections** — The W3Schools page also references additional button sections (e.g. hoverable buttons, button shadow, disabled buttons, button width, button groups, animated buttons). The verbatim code for those sections was not captured from this source on this fetch; for hoverable/shadow/disabled/width specifics see [[CSS Button Hover Effects]]. Other section code: Not found in source (for this page).
