## Supported Elements

React attempts to support all common elements in both HTML and SVG. Any lower case tag in JSX will be rendered to an element with that tag. SVG elements must be contained within an `<svg>` element to work properly.

### Using `React.DOM` Factory methods

If you aren't using JSX and are using the `React.DOM.*` API to create elements, then you are slightly more limited and there is list of supported elements that will be available on that API.

#### HTML Elements

The following HTML elements are supported in `React.DOM.*`:

```
a abbr address area article aside audio b base bdi bdo big blockquote body br
button canvas caption cite code col colgroup data datalist dd del details dfn
dialog div dl dt em embed fieldset figcaption figure footer form h1 h2 h3 h4 h5
h6 head header hgroup hr html i iframe img input ins kbd keygen label legend li
link main map mark menu menuitem meta meter nav noscript object ol optgroup
option output p param picture pre progress q rp rt ruby s samp script section
select small source span strong style sub summary sup table tbody td textarea
tfoot th thead time title tr track u ul var video wbr
```

#### SVG elements

The following SVG elements are supported in `React.DOM.*`:

```
circle clipPath defs ellipse g image line linearGradient mask path pattern
polygon polyline radialGradient rect stop svg text tspan
```

## Supported Attributes

React supports all `data-*` and `aria-*` attributes as well as every attribute in the following lists.

> Note:
>
> All attributes are camel-cased and the attributes `class` and `for` are `className` and `htmlFor`, respectively, to match the DOM API specification.

For a list of events, see [Supported Events](/react/docs/events.html).

### HTML Attributes

These standard attributes are supported:

```
accept acceptCharset accessKey action allowFullScreen allowTransparency alt
async autoComplete autoFocus autoPlay capture cellPadding cellSpacing challenge
charSet checked cite classID className colSpan cols content contentEditable
contextMenu controls coords crossOrigin data dateTime default defer dir
disabled download draggable encType form formAction formEncType formMethod
formNoValidate formTarget frameBorder headers height hidden high href hrefLang
htmlFor httpEquiv icon id inputMode integrity is keyParams keyType kind label
lang list loop low manifest marginHeight marginWidth max maxLength media
mediaGroup method min minLength multiple muted name noValidate nonce open
optimum pattern placeholder poster preload profile radioGroup readOnly rel
required reversed role rowSpan rows sandbox scope scoped scrolling seamless
selected shape size sizes span spellCheck src srcDoc srcLang srcSet start step
style summary tabIndex target title type useMap value width wmode wrap
```

These RDFa attributes are supported (several RDFa attributes overlap with standard HTML attributes and thus are excluded from this list):

```
about datatype inlist prefix property resource typeof vocab
```

In addition, the following non-standard attributes are supported:

- `autoCapitalize autoCorrect` for Mobile Safari.
- `color` for `<link rel="mask-icon" />` in Safari.
- `itemProp itemScope itemType itemRef itemID` for [HTML5 microdata](http://schema.org/docs/gs.html).
- `security` for older versions of Internet Explorer.
- `unselectable` for Internet Explorer.
- `results autoSave` for WebKit/Blink input fields of type `search`.

There is also 2 React-specific attributes:
- `dangerouslySetInnerHTML` ([more here](/react/docs/special-non-dom-attributes.html)), used for directly inserting HTML strings into a component.
- `suppressContentEditableWarning`, used to suppress the warning when using `contentEditable` and `children`.
