# [[CSS Position Offsets]]

## 🎯 한 줄 통찰 (One-line insight)
The `top`, `right`, `bottom`, and `left` properties position elements — but they only take effect on positioned elements (those with `position` set to `relative`, `absolute`, `fixed`, or `sticky`). [S1]

## 🧠 핵심 개념 (Core concepts)
- **offset properties** — `top`, `right`, `bottom`, and `left` are used to position elements. [S1]
- **only on positioned elements** — these properties only work on positioned elements, i.e. elements with `position` set to `relative`, `absolute`, `fixed`, or `sticky`. [S1]
- **margin-edge semantics** — each offset sets the corresponding margin edge for a positioned box (top/right/bottom/left margin edge). [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Positioned + offset** — set a `position` value other than `static` first, then use offset properties to move the element; offsets are ignored on static elements. [S1]
- **Corner/center placement** — use combinations of offsets on an absolutely positioned element to place text at an image's corners or center. [S1]

## 📖 세부 내용 (Details)
**Positioning with top, right, bottom, and left** [S1]
The `top`, `right`, `bottom`, and `left` properties are used to position elements. These properties only work on **positioned elements** (elements with `position` set to `relative`, `absolute`, `fixed`, or `sticky`).

**Positioning Text On an Image** [S1]
This section demonstrates practical application with an example showing text positioned at various corners and center of an image. The page provides five interactive "Try it Yourself" examples: Top Left, Top Right, Bottom Left, Bottom Right, and Centered. The exact verbatim CSS for each variant was not provided in the fetched source — Not found in source.

**CSS Positioning Properties Reference Table** [S1]

| Property | Description |
|----------|-------------|
| bottom | Sets the bottom margin edge for a positioned box |
| clip | Clips an absolutely positioned element |
| left | Sets the left margin edge for a positioned box |
| position | Specifies the type of positioning for an element |
| right | Sets the right margin edge for a positioned box |
| top | Sets the top margin edge for a positioned box |

## 🛠️ 적용 사례 (Applied in summary)
The page's applied example is positioning text at the corners and center of an image using offset properties on positioned elements. No external project/commit applications found in the source.

## 💻 코드 패턴 (Code patterns)
General shape — offsets only apply once an element is positioned (language: CSS):
```css
selector {
  position: absolute; /* or relative, fixed, sticky */
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
}
```
Note: this skeleton illustrates the rule that offsets require a non-static `position`; the page did not provide verbatim per-corner example code — Not found in source. [S1]
