如何在 HTML5 表单必填属性上设置验证消息的时间？

Question

I am using HTML5. On form validation, the message will be shown for about 5 seconds. How to change it to be visible for 10 seconds?

 <form> <input name="name" required /> <input type="submit" value="Submit"/> </form>

The UI is implemented by the browser and isn't customisable. Different browsers will implement it differently. (eg when I test it, the message is displayed until I interact with the page again).
