 # Handling events
 
-<!-- TODO: write content for this page -->
+Since the input is [uncontrolled](/fundamentals/core-concepts#the-input-is-uncontrolled),
+events are how you observe it. You change content by calling ref methods; you
+react to changes by listening to the callbacks below.
+
+Full payload shapes of the available callbacks can be found in the `EnrichedTextInput` reference.
+
+## Content
+
+- **`onChangeText`** - plain-text content changed.
+- **`onChangeHtml`** - the HTML changed.
+
+:::tip
+
+The `onChangeHtml` callback has to parse the content into HTML on every keystroke.
+This is a heavy computational operation that might slow down your app's performance. Consider using the `getHTML()` ref method instead if it meets your requirements.
+
+:::
+
+## Selection and style state
+
+- **`onChangeSelection`** - the cursor moved or the selection changed. Gives you
+  `start`, `end`, and the selected `text`. Useful for range-based methods like
+  [`setLink`](/rich-text-formatting/links).
+- **`onChangeState`** - the active styles at the cursor changed. This is the
+  event that drives a toolbar by using reported `isActive`, `isBlocking`, and
+  `isConflicting`, plus the current `alignment`. See the
+  [style state model](/fundamentals/core-concepts#the-style-state-model).
+
+## Focus
+
+- **`onFocus`** / **`onBlur`** - the input gained or lost focus.
+
+## Mentions
+
+- **`onStartMention`** - a mention started being edited.
+- **`onChangeMention`** - the query after the indicator changed.
+- **`onEndMention`** - editing a mention stopped.
+- **`onMentionDetected`** - the cursor entered or left a mention.
+
+## Links
+
+- **`onLinkDetected`** - the cursor entered or left a link.
+
+## Images
+
+- **`onPasteImages`** - the user pasted one or more images; hands you each
+  image's data so you can upload and insert them with
+  [`setImage`](/rich-text-formatting/inline-images).
+
+## Keyboard and submission
+
+- **`onKeyPress`** - a key was pressed.
+- **`onSubmitEditing`** - the user presses return/enter key. Fires when `submitBehavior` is set to either `submit` or `blurAndSubmit`.

+
+# Rendering rich text
+
+`EnrichedTextInput` is for editing. To _display_ rich text without an editor -
+a chat message, a comment, an article - use its read-only counterpart,
+**`EnrichedText`**.
+
+Both components speak the same [HTML format](/fundamentals/html-format-and-supported-tags),
+so the typical flow is: edit in `EnrichedTextInput`, persist the
+`getHTML` output, and later feed that
+string to `EnrichedText`.
+
+## Passing content
+
+`EnrichedText` takes the HTML string as its `children`:
+
+```tsx
+import { EnrichedText } from 'react-native-enriched-html';
+
+<EnrichedText>{'<p>Hello <b>world</b></p>'}</EnrichedText>;
+```
+
+## Styling
+
+Styling mirrors the input. `style` controls the container and base typography,
+and `htmlStyle` controls per-element appearance. `EnrichedText` extends
+`htmlStyle` with **press states** for interactive elements, since links and
+mentions are pressable here:
+
+```tsx
+<EnrichedText
+  style={{ fontSize: 16, color: '#232736' }}
+  htmlStyle={{
+    a: { pressColor: '#1e40af' },
+    mention: { pressColor: '#16a34a', pressBackgroundColor: '#dcfce7' },
+  }}>
+  {html}
+</EnrichedText>
+```
+
+The added `pressColor` / `pressBackgroundColor` fields on `a` and `mention` are
+the only shape difference from the input's `htmlStyle`. See the
+[`EnrichedText`](/api-reference/enriched-text) reference for the full type.
+
+## Notable props
+
+- **`selectable`** - allow the user to select and copy the rendered text.
+  Defaults to `false`.
+- **`onLinkPress` / `onMentionPress`** - fire when a link or mention is pressed.
+- **`numberOfLines` / `ellipsizeMode`** - truncate long content to a fixed
+  number of lines with an ellipsis.
+- **`useHtmlNormalizer`** - normalize external or messy HTML into the library's canonical
+  tag subset before rendering. Defaults to `true`. See
+  [Normalization](/fundamentals/core-concepts#normalization).
+
+:::note
+
+On web, the default behavior of the pressed `<a>` tag is suppressed. To navigate to the link's URL, you need to properly handle the `onLinkPress` event.
+
+:::
+
+## Try it out
+
+Format some text in the editor, then press **Render** - the current HTML is read
+with `getHTML()` and handed to an `EnrichedText` below.
+
+<InteractiveExample src={RenderingEditorSrc} component={RenderingEditor} />
+
+:::caution
+
+On iOS and Android, `EnrichedText` does not sanitize HTML for you. Sanitize anything you render that
+came from users or other untrusted sources. To know more about the web's built-in sanitization, visit [Web support](/core-functionalities/web-support#sanitization).

 # Styling the input
 
-<!-- TODO: write content for this page -->
+`EnrichedTextInput` is styled through two separate props. Together they cover
+everything from the container's dimensions down to the color of a bullet point.
+
+- **`style`** - the container's layout behavior and its base typography (`fontSize`, `color`, `fontFamily`, …). It accepts a subset of React Native's `TextStyle`, described by
+  `EnrichedInputStyle`.
+- **`htmlStyle`** - the appearance of individual rich text elements: heading
+  sizes, blockquote borders, code colors, list markers, mention colors, and so
+  on.
+
+```tsx
+<EnrichedTextInput
+  style={{
+    fontSize: 16,
+    color: '#232736',
+    padding: 12,
+    borderRadius: 12,
+    backgroundColor: '#eef0ff',
+  }}
+  htmlStyle={{
+    h1: { fontSize: 28, bold: true },
+    blockquote: { borderColor: '#57b495', borderWidth: 3 },
+    code: { color: '#c026d3' },
+  }}
+/>
+```
+
+## `htmlStyle`
+
+`htmlStyle` maps each supported element to a small config object. Anything you
+omit falls back to the built-in default. The available keys are:
+
+| Key          | Styles         | Notable options                                             |
+| ------------ | -------------- | ----------------------------------------------------------- |
+| `h1`–`h6`    | Headings       | `fontSize`, `bold`                                          |
+| `blockquote` | Blockquote     | `borderColor`, `borderWidth`, `gapWidth`, `color`           |
+| `codeblock`  | Code block     | `color`, `backgroundColor`, `borderRadius`                  |
+| `code`       | Inline code    | `color`, `backgroundColor`                                  |
+| `a`          | Links          | `color`, `textDecorationLine`                               |
+| `mention`    | Mentions       | `color`, `backgroundColor`, `textDecorationLine`            |
+| `ol`         | Ordered list   | `markerColor`, `markerFontWeight`, `marginLeft`, `gapWidth` |
+| `ul`         | Unordered list | `bulletColor`, `bulletSize`, `marginLeft`, `gapWidth`       |
+| `ulCheckbox` | Checkbox list  | `boxColor`, `boxSize`, `marginLeft`, `gapWidth`             |
+
+The full list of properties, defaults, and platform notes lives in the
+`EnrichedTextInput` reference.
+
+### Styling mentions per indicator
+
+`mention` accepts either a single config applied to every mention, or a record
+keyed by [indicator](/rich-text-formatting/mentions) so each mention type gets
+its own look:
+
+```tsx
+htmlStyle={{
+  mention: {
+    '@': { color: '#2563eb', backgroundColor: '#dbeafe' },
+    '#': { color: '#16a34a', backgroundColor: '#dcfce7' },
+  },
+}}
+```
+
+:::tip
+
+You can also create a default `mention` style config, by using the `'default'` key.
+
+```tsx
+htmlStyle={{
+  mention: {
+    'default': { color: '#2563eb', backgroundColor: '#dbeafe' },
+    '#': { color: '#16a34a', backgroundColor: '#dcfce7' },
+  },
+}}
+```
+
+This way you can create a style for any mention indicator to fallback if it doesn't have one fully defined.

 # Web support
 
-<!-- TODO: write content for this page -->
+Both `EnrichedTextInput` and `EnrichedText` run on the web. On native the editor
+is backed by the platform's text engine; on the web it is built on
+[Tiptap](https://tiptap.dev/) (on top of ProseMirror). That implementation
+detail stays behind the same public API.
+
+## One API across platforms
+
+The web build exposes the **same props, ref methods, and events** as native.
+Events keep their native shape too - they arrive as
+`NativeSyntheticEvent`, read off `e.nativeEvent`, so
+[event-handling](/core-functionalities/handling-events) code is portable as-is:
+
+```tsx
+<EnrichedTextInput
+  onChangeHtml={e => setHtml(e.nativeEvent.value)}
+  onChangeState={e => setState(e.nativeEvent)}
+/>
+```
+
+The interactive examples throughout these docs are the web build running live.
+
+## Keyboard shortcuts
+
+The web editor ships desktop-style formatting shortcuts out of the box, along
+with native browser **undo/redo**.
+
+| Action              | macOS          | Windows / Linux             |
+| ------------------- | -------------- | --------------------------- |
+| Bold                | `⌘B`           | `Ctrl+B`                    |
+| Italic              | `⌘I`           | `Ctrl+I`                    |
+| Underline           | `⌘U`           | `Ctrl+U`                    |
+| Strikethrough       | `⌘⇧X`          | `Ctrl+Shift+X`              |
+| Inline code         | `⌘⇧C`          | `Ctrl+Shift+C`              |
+| Code block          | `⌘⌥⇧C`         | `Ctrl+Alt+Shift+C`          |
+| Normal paragraph    | `⌘⌥0`          | `Ctrl+Alt+0`                |
+| Heading 1–6         | `⌘⌥1` – `⌘⌥6`  | `Ctrl+Alt+1` – `Ctrl+Alt+6` |
+| Numbered list       | `⌘⇧7`          | `Ctrl+Shift+7`              |
+| Unordered list      | `⌘⇧8`          | `Ctrl+Shift+8`              |
+| Checkbox list       | `⌘⇧9`          | `Ctrl+Shift+9`              |
+| Paste as plain text | `⌘⇧V`          | `Ctrl+Shift+V`              |
+| Undo                | `⌘Z`           | `Ctrl+Z`                    |
+| Redo                | `⌘⇧Z`          | `Ctrl+Shift+Z`              |
+| Select all          | `⌘A`           | `Ctrl+A`                    |
+
+## Platform differences
+
+A few native-only features have no web equivalent and are ignored there:
+
+- **`contextMenuItems`** - the native editing menu isn't available; use your own
+  UI instead.
+- **`returnKeyLabel`** - can't be set inside a browser. `returnKeyType` maps to
+  the browser's [`enterkeyhint`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/enterkeyhint).
+- **RN layout ref methods** - `measure`, `measureInWindow`, `measureLayout`, and
+  `setNativeProps` are no-ops.
+
+The [`EnrichedTextInput`](/api-reference/enriched-text-input) and
+[`EnrichedText`](/api-reference/enriched-text) references note per-prop platform
+support.
+
+:::note
+
+On web, `onPasteImages` gives each image a `blob:` URL. If you hold onto those
+URIs, call `URL.revokeObjectURL(uri)` once you're done with them (e.g. after an
+upload) so the browser can release the memory.
+
+:::
+
+## Sanitization
+
+Unlike the native platforms, the web build sanitizes HTML for you. It runs
+[DOMPurify](https://github.com/cure53/DOMPurify) at **every entrypoint** - the
+`children` of `EnrichedText`, and `defaultValue`, `setValue`, and pasted content
+on `EnrichedTextInput`. Sanitization is also run on the input component's **output** - `getHTML()`.
+This ensures untrusted markup can't inject scripts or unsafe attributes into the DOM.
+
+:::note
+
+Sanitization can be customized with the `sanitizationConfig` prop. It allows you to set a `linkRegex` that
+will define, which URI-containing attributes will actually be preserved by the sanitizer.
+
+:::
+
+## Server-side rendering
+
+The library does **not** support SSR. Normalization and sanitization both need a
+DOM to work against, which isn't available during server rendering. In an SSR
+framework (Next.js, Remix, …), make sure both `EnrichedTextInput` and
+`EnrichedText` render **client-side only**.
