Safari sometimes forces video full screen playback due to website settings, automatic playback behavior and its own restrictions, mainly on iOS devices. 1. Safari's automatic playback strategy forces full screen: If videos on iOS are automatically played with sound, full screen will often be triggered. Apple's move is to prevent noise and save resources; users can mute the screen in advance, quickly click on the screen, or use websites that do not force automatic playback to avoid it. 2. Video tag configuration results in full screen: If the website does not correctly set the playsinline attribute, Safari will default to full screen; developers should add this attribute and test it, and users can feedback questions or use another browser instead. 3. The difference between iOS version and browser affects the playback behavior: iOS 10 supports inline playback but depends on the correct configuration of the website. Older versions of code may cause inconsistent behavior; if you encounter this problem frequently, you can try to update the system. Understanding these factors helps to predict and bypass the phenomenon.
Safari sometimes plays videos in full screen automatically due to a combination of website settings, autoplay behavior, and Safari's own restrictions on video playback. This behavior is most common on iOS devices and can be frustrating if you're just trying to watch a video inline while browsing.
Here's why it happens and how to handle it:
1. Safari's Autoplay Policy Forces Full Screen
On iOS, Safari has strict rules about video autoplay. If a video starts playing automatically—especially with sound—it often jumps to full screen. Apple designed it this way to prevent unwanted noise and conserve resources.
- What triggers it: Videos that autoplay with sound are more likely to go full screen.
- How to avoid it:
- Mute the video before it plays.
- Tap the screen quickly when the video starts—this can sometimes stop the full-screen transition.
- Use websites that respect user preferences by not forcing autoplay.
This restriction applies mostly to mobile Safari. On desktop versions, videos usually play inline without going full screen unless coded otherwise.
2. Video Tags Are Configured for Full Screen
Some websites embedded videos using HTML5 <video></video> tags with specific attributes like webkit-playsinline or playsinline . If those attributes are missing or set incorrectly, Safari defaults to full screen.
- Playsinline vs. Not: On iOS, videos won't stay inline unless
playsinlineis explicitly set. - What developers should do: Include
playsinlineand test playback behavior across iOS versions. - What users can do: There's no direct fix unless you control the site code. You can report the issue to the website owner or use an alternative browser like Chrome, which sometimes handles inline playback differently.
3. iOS Version and Browser Differences Matter
The version of iOS you're running affects how Safari behaves with video playback. Older versions had stricter limitations, but newer ones offer better support for inline playback—assuming the website uses the correct settings.
- iOS 10 improvements: Starting from iOS 10, Safari allows inline playback as long as the video is muted or has the right attributes.
- Still inconsistent: Some sites haven't updated their code to match these standards, leading to unpredictable behavior.
- Try updating iOS: If you're seeing this issue frequently, make sure your device is running the latest OS version.
If you're a developer or someone embedding videos on a website, double-check your video tag setup and test across different iOS versions.
Basically, Safari forces videos to full screen mainly due to autoplay policies and how the video is embedded. It's not always easy to predict, but understanding these factors helps you know what to expect—and how to work around it.

How to simulate different timezones in Chrome
Jul 13, 2025 am 12:19 AM
To test page behavior in different time zones in Chrome, there are three ways to do it. 1. Use ChromeDevTools to simulate the time zone: Open DevTools → Click on three points → MoreTools → Sensors, check the overlay option in the DateandTime section and select the target time zone. This setting only takes effect in the current session; 2. Specify the time zone through the command line startup parameters: close all Chrome instances and execute chrome.exe--timezone="target time zone" to affect the entire browser instance; 3. Use JavaScript to overwrite the behavior of the Date object, and the fixed time value is used to accurately control the JS time.
