Article Introduction：To hide the search bar at the top of the iPhone home screen, the specific method depends on the iOS version. If you use iOS16 or update the system, you can enter editing mode, select "Custom Home Screen", and save after setting it to "Hide" in the "Search" section. For iOS 15 and earlier, the search bar cannot be completely hidden, but it can be restricted by turning off "Siri and Search" or consider upgrading the system. Even if the search bar is disabled on the iPhone with Home button, the sliding gesture will still bring up the search box. There is currently no official method to completely remove it. Overall, iOS 16 and above users are easy to operate, while other users need to compromise or wait for updates.

Article Introduction：When making a chat application interface, using HTML to build structure is a basic and critical step, which directly affects subsequent styles and interactions. First of all, the chat interface is generally divided into three parts: the top title bar, the message display area, and the input area. It is recommended to use a div to wrap the entire container and subdivate the area, with a clear structure for easy expansion. Secondly, each message is recommended to be wrapped with a div or li, including the sender, content, and time, and add incoming or outgoing classes according to the message type to distinguish styles. Third, the input area should include an input box and a send button, which supports carriage return sending and empty message judgment, and reserve space for automatically expanding the height. In addition, you need to pay attention to the message order, avoid too deep structure nesting, and use semantic tags reasonably to ensure that the HTML structure is simple and has
