For a common Element, first add an atip class in the class and add the corresponding value.
Data-toggle unchangeable data-placement can be set to top | bottom | left | right | auto. title is not empty, the title is displayed; otherwise, the data-original-title is displayed.


2. Of course, the most basic files must be imported.
Then write a JS script.
Trigger: How tooltip is triggered-click | hover | focus | manual. For other attributes, refer to the corresponding API

Name	Type	Default	Description
Animation	Boolean	True	Apply a CSS fade transition to the tooltip
Container	String | false	False	Appends the tooltip to a specific element. Example:container: 'body'. This option is special useful in that it allows you to position the tooltip in the flow of the document near the triggering element-which will prevent the tooltip from floating away from the triggering element during a window resize.
Delay	Number | object	0	Delay showing and hiding the tooltip (MS)-does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is:delay: { "show": 500, "hide": 100 }
Html	Boolean	False	Insert HTML into the tooltip. If false, jQuery'stextMethod will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
Placement	String | function	'Top'	How to position the tooltip-top | bottom | left | right | auto. When "auto" is specified, it will dynamically reorient the tooltip. for example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right. When a function is used to determine the placement, it is called with the tooltip DOM node as its first argument and the triggering element DOM node as its second.thisContext is set to the tooltip instance.
Selector	String	False	If a selector is provided, tooltip objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have tooltips added. Seethisandan informative example.
Template	String	'<div class="tooltip" role="tooltip"><div class="tooltip-arrow"></div><div class="tooltip-inner"></div></div>'	Base HTML to use when creating the tooltip. The tooltip'stitleWill be injected into.tooltip-inner. .tooltip-arrowWill become the tooltip's arrow. The outermost wrapper element shoshould have.tooltipClass.
Title	String | function	''	Default title value iftitleAttribute isn't present. If a function is given, it will be called with itsthisReference set to the element that the tooltip is attached.
Trigger	String	'Hover focal s'	How tooltip is triggered-click | hover | focus | manual. You may pass multiple triggers; separate them with a space.
Viewport	String | object	{Selector: 'body', padding: 0}	Keeps the tooltip within the bounds of this element. Example:viewport: '#viewport'Or{ "selector": "#viewport", "padding": 0 }
