Meta tags

# default-style

Selects the preferred CSS style sheet set by name when a page offers alternate titled stylesheets. Browser support is limited.

## Code examples

Good example

```
<meta http-equiv="default-style" content="Main Style">
```

Valid when a linked stylesheet set has the exact title Main Style.

Avoid this example

```
<meta http-equiv="default-style" content="incorrectTitle">
```

A value with no matching stylesheet title cannot select a preferred set.

## Recommendations

- 01 Match the Stylesheet Title The value must match the title of the preferred stylesheet set exactly, including letter case.
- 02 Do Not Depend on It Current support is narrow. If choosing a theme is important, provide a visible control and persist the user’s choice yourself.

## Related meta tags

### [Content-Security-Policy](https://zhead.dev/meta/content-security-policy)

http-equiv

Enforces a Content Security Policy from the document head. A policy limits where scripts, styles, images, connections, and other resources can come from, which reduces the impact of content injection bugs.

```
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; object-src 'none'; base-uri 'self';">
```

Uses the same origin by default, blocks plugin content, and limits base URLs to the same origin.

### [content-type](https://zhead.dev/meta/content-type)

http-equiv

Provides the legacy pragma form of an HTML character encoding declaration. For conforming HTML, its content must be text/html; charset=utf-8.

```
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
```

The only conforming content value for this pragma in an HTML document.

### [default-style](https://zhead.dev/meta/default-style)

http-equiv

Selects the preferred CSS style sheet set by name when a page offers alternate titled stylesheets. Browser support is limited.

```
<meta http-equiv="default-style" content="Main Style">
```

Valid when a linked stylesheet set has the exact title Main Style.

### [refresh](https://zhead.dev/meta/refresh)

http-equiv

Reloads the current page after a delay or performs a timed redirect. Automatic navigation can confuse users, so a server redirect is usually a better choice.

```
<meta http-equiv="refresh" content="5; URL=https://example.com/next">
```

Valid timed redirect syntax. Prefer an HTTP redirect unless the visible delay serves a real purpose.

### [X-UA-Compatible](https://zhead.dev/meta/x-ua-compatible)

http-equiv

A legacy Internet Explorer pragma whose only conforming value is IE=edge. Current user agents must ignore it, so new pages should omit it.

```
<meta http-equiv="X-UA-Compatible" content="IE=edge">
```

The only value allowed by the HTML standard, kept here for reading legacy markup. Current browsers ignore it.
