# [[HTML Favicon]]
|
|
|
|
## 🎯 한 줄 통찰 (One-line insight)
|
|
A favicon is a small image displayed next to the page title in the browser tab, added by placing a `<link rel="icon">` element in the document's `<head>`. [S1]
|
|
|
|
## 🧠 핵심 개념 (Core concepts)
|
|
- **What a favicon is** — a small image displayed next to the page title in the browser tab. [S1]
|
|
- **Design guidance** — since a favicon is a small image, it should be a simple image with high contrast. [S1]
|
|
- **How to add it** — use the HTML `<link>` element inside the `<head>` section (after the `<title>` element); favicons can be sourced from sites like favicon.cc or custom-created. [S1]
|
|
- **File placement** — put the favicon in the site's root directory or an `/images` folder. [S1]
|
|
- **Format support** — ICO, PNG, GIF, JPEG, and SVG favicon formats are supported across Edge, Chrome, Firefox, Opera, and Safari. [S1]
|
|
|
|
## 🧩 추출된 패턴 (Extracted patterns)
|
|
- **Favicon link pattern** — `<link rel="icon" type="image/x-icon" href="/images/favicon.ico">` placed in `<head>`. [S1]
|
|
- **Head-placement pattern** — the `<link>` goes after the `<title>` element. [S1]

**Adding a favicon**
|
|
Favicons can be sourced from sites like favicon.cc or custom-created images. A favicon is a small image, so it should be a simple image with high contrast. Place the favicon in your site's root directory or an `/images` folder, then add a `<link>` element to your HTML `<head>` section after the `<title>` element. [S1]
|
|
```html
|
|
<!DOCTYPE html>
|
|
<html>
|
|
<head>
|
|
<title>My Page Title</title>
|
|
<link rel="icon" type="image/x-icon" href="/images/favicon.ico">
|
|
</head>
|
|
<body>
|
|
<h1>This is a Heading</h1>
|
|
<p>This is a paragraph.</p>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|

The guide includes a compatibility matrix showing support across Edge, Chrome, Firefox, Opera, and Safari: [S1]
