# [[CSS Image Shapes]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
With CSS it is easy to shape (clip) images to circles, ellipses, and polygons using the `clip-path` property, while `shape-outside` lets inline content wrap around the shaped image. [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **`clip-path`** — lets you clip an element to a basic shape or to an SVG source. [S1]
|
||||
- **`shape-outside`** — lets you define a shape for the wrapping of the inline content. [S1]
|
||||
- **`circle()`** — defines a circle with a radius and a position. [S1]
|
||||
- **`ellipse()`** — defines an ellipse with two radii, x and y. [S1]
|
||||
- **`polygon()`** — defines a polygon. [S1]
|
||||
|
||||
## 🧩 추출된 패턴 (Extracted patterns)
|
||||
- **Clip to a basic shape** — apply a shape function (`circle()`, `ellipse()`, `polygon()`) as the value of `clip-path` on an image. [S1]
|
||||
- **Reposition the clip** — use the `at` keyword inside a shape function (e.g. `circle(50% at right)`) to move the clip's center. [S1]
|
||||
- **Wrap text around a shape** — combine `float` with `clip-path` (visual clip) and `shape-outside` (the wrap geometry) so inline content flows around the shaped image. [S1]

||||
## 📖 세부 내용 (Details)
|
||||
**Shaping images** — With CSS it is easy to shape (clip) images to circles, ellipses and polygons. [S1]
|
||||
|
||||
**Circle with `clip-path`** [S1]
|
||||
```css
|
||||
img {
|
||||
clip-path: circle(50%);
|
||||
}
|
||||
```
|
||||
|
||||
**Circle positioned to the right** — the `at` keyword positions the circle. [S1]
|
||||
```css
|
||||
img {
|
||||
clip-path: circle(50% at right);
|
||||
}
|
||||
```
|
||||
|
||||
**Circle with `shape-outside`** — the `shape-outside` property lets you define a shape for the wrapping of the inline content. [S1]
|
||||
```css
|
||||
img {
|
||||
float: left;
|
||||
clip-path: circle(40%);
|
||||
shape-outside: circle(45%);
|
||||
}
|
||||
```
|
||||
|
||||
**Ellipse with `clip-path`** — the `ellipse()` function defines an ellipse with two radii x and y. [S1]
|
||||
```css
|
||||
img {
|
||||
clip-path: ellipse(50% 35%);
|
||||
}
|
||||
```
|
||||
|
||||
**Ellipse positioned to the right** [S1]
|
||||
```css
|
||||
img {
|
||||
clip-path: ellipse(50% 35% at right);
|
||||
}
|
||||
```
|
||||
|
||||
**Ellipse with `shape-outside`** [S1]
|
||||
```css
|
||||
img {
|
||||
float: left;
|
||||
clip-path: ellipse(40% 50%);
|
||||
shape-outside: ellipse(45% 50%);
|
||||
}
|
||||
```
|
||||
|
||||
**Polygon with `clip-path`** — the `polygon()` function defines a polygon. [S1]
|
||||
```css
|
||||
img {
|
||||
clip-path: polygon(50% 0%, 100% 50%, 50% 100%, 0% 50%);
|
||||
}
|
||||
```
|
||||
|
||||
**Properties and functions reference** [S1]
|
||||
|
||||
| Property / Function | Description |
|
||||
|---|---|
|
||||
| `clip-path` | Lets you clip an element to a basic shape or to an SVG source |
|
||||
| `shape-outside` | Lets you define a shape for the wrapping of the inline content |
|
||||
| `circle()` | Defines a circle with a radius and a position |
|
||||
| `ellipse()` | Defines an ellipse with two radii x and y |

## 🛠️ 적용 사례 (Applied in summary)
|
||||
The page's own examples are the applied cases: circular/elliptical/polygonal image clips, and text-wrapping layouts where a floated image uses `shape-outside`. No external project/commit applications found in the source.
|
||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
Clip an image to a centered circle (language: CSS):
|
||||
```css
|
||||
img {
|
||||
clip-path: circle(50%);
|
||||
}
|
||||
```
|
||||
Wrap inline text around a circular image (language: CSS):
|
||||
```css
|
||||
img {
|
||||
float: left;
|
||||
clip-path: circle(40%);
|
||||
shape-outside: circle(45%);
|
||||
}
|
||||
```
|
||||
|
||||
## ⚖️ 모순 및 업데이트 (Contradictions & updates)

||||
