HTML title attribute display exception: What should I do if the super long text levitation prompts fail?

Solve the problem of failure of HTML title attribute's super long text suspension prompt

In web development, title attribute is often used to create mouse hover prompts. But when the text is too long, the prompt may not be fully displayed. This article analyzes a case reported by users: at 1920x1080 resolution and 125% scaling, the hover prompt of the ultra-long title attribute text is invalid.

This problem is not reproduced in all browsers and environments. First, verify that title attribute is rendered correctly. It is recommended to use the browser developer tool (F12) to check element attributes and page rendering to confirm whether title attribute value has been correctly added to the HTML element. If not rendered, the problem may be in the code logic or browser compatibility, and you need to check for code errors or perform compatibility processing.

If title attribute has been rendered correctly but the prompt still does not display, it may be that the browser or operating system has a limit on title attribute length. At this time, it is recommended to use a more powerful UI component library to replace the native title attribute. For example, ElementUI's Tooltip component allows custom prompt information and better control of the display method and length of prompt content, thereby avoiding display problems caused by excessive title attributes and providing users with a more friendly experience. This is a more reliable solution than relying on native title properties.
