Web Inspector expands Safari on iPhone and iPad with a set of web development tools:
Elements: Browse the DOM tree and tap elements on the page to inspect them. View node details, styles, and computed values. Search the DOM, edit an element's HTML, and copy or delete nodes.
Console: Type JavaScript commands to debug, modify, and get information about your webpage.
Sources: Read the webpage's source with syntax highlighting.
Network: See a list of network requests made by the webpage, with headers and responses. Filter requests, or copy one as a cURL command.
Resources: Find details about the data stored by a webpage, such as cookies, local storage, and session storage.
Tip: If you tap the Web Inspector button and nothing happens, reload the page once..
