# [[CSS Inline-block]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
`display: inline-block` makes an element flow on the same line as other inline/inline-block elements while still accepting `width`, `height`, `margin-top`, and `margin-bottom` like a block element — the bridge between inline and block behavior. [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **Definition** — an element with `display: inline-block` will appear on the same line as other inline or inline-block elements. [S1]
|
||||
- **Block-like sizing on an inline-flow element** — in addition to flowing inline, you can set `width`, `height`, `margin-top`, and `margin-bottom` for the element (like block elements). [S1]
|
||||
- **Contrast with `display: inline`** — pure inline elements (such as the default `span`) ignore width/height. [S1]
|
||||
- **Contrast with `display: block`** — block elements take a full line, breaking the inline flow. [S1]
|
||||
- **Common use case** — building a horizontal navigation menu from list items. [S1]
|
||||
|
||||
## 🧩 추출된 패턴 (Extracted patterns)
|
||||
- **Three-way display comparison** — placing `inline`, `inline-block`, and `block` spans side by side reveals which respect width/height and which break onto new lines. [S1]
|
||||
- **Horizontal menu pattern** — strip list styling and set `display: inline-block` on `li` elements to lay menu items out in a row. [S1]
|
||||
|
||||
## 📖 세부 내용 (Details)
|
||||
**What is inline-block?**
|
||||
An element with `display: inline-block` will appear on the same line as other inline or inline-block elements. In addition, you can set the `width`, `height`, `margin-top`, and `margin-bottom` properties for the element (like block elements). [S1]
|
||||
|
||||
**Comparing display values**
|
||||
The following example shows the different behavior of `display: inline`, `display: inline-block` and `display: block`: [S1]
|
||||
```css
|
||||
span.a {
|
||||
display: inline; /* the default for span */
|
||||
padding: 5px;
|
||||
border: 2px solid red;
|
||||
}
|
||||
|
||||
span.b {
|
||||
display: inline-block;
|
||||
width: 100px;
|
||||
height: 35px;
|
||||
padding: 5px;
|
||||
border: 2px solid red;
|
||||
}
|
||||
|
||||
span.c {
|
||||
display: block;
|
||||
width: 100px;
|
||||
height: 35px;
|
||||
padding: 5px;
|
||||
border: 2px solid red;
|
||||
}
|
||||
```
|
||||
|
||||
**Horizontal navigation menu**
|
||||
A common use of `display: inline-block` is to create a horizontal navigation menu: [S1]
|
||||
```css
|
||||
.nav {
|
||||
background-color: lightgray;
|
||||
list-style-type: none;
|
||||
padding: 0;
|
||||
margin: 0;
|
||||
}
|
||||
|
||||
.nav li {
|
||||
display: inline-block;
|
||||
font-size: 18px;
|
||||
padding: 15px;
|
||||
}
|
||||
```
|
||||
|
||||
**Property reference** [S1]
|
||||
|
||||
| Property | Description |
|
||||
|----------|-------------|
|
||||
| `display` | Specifies the display behavior (the type of rendering box) of an element |
|
||||
|
||||
## 🛠️ 적용 사례 (Applied in summary)
|
||||
The page's own applied examples are the inline/inline-block/block span comparison and the horizontal navigation menu built from `inline-block` list items. No external project/commit applications found in the source.
|
||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
Horizontal menu via inline-block (language: CSS):
|
||||
```css
|
||||
.nav li {
|
||||
display: inline-block;
|
||||
font-size: 18px;
|
||||
padding: 15px;
|
||||
}
|
||||
```
|
||||
|
||||
## ⚖️ 비교 및 선택 기준 (Comparison & decision criteria)
|
||||
- **`inline` vs `inline-block` vs `block`** — `inline` (default for `span`) ignores width/height; `inline-block` stays on the same line yet accepts width, height, and top/bottom margins; `block` takes a full line. Choose `inline-block` when you need elements in a row that still respect explicit dimensions. [S1]
|
||||
|
||||
## ⚖️ 모순 및 업데이트 (Contradictions & updates)
|
||||
No contradictions found in the source.
