Introduction to HTML Tooltip
Tooltip is a concept used in HTML for showing some extra information about the specifically selected element. This can be done on the mouse hover effect whenever the user moves the mouse over an element that is using a tooltip to display specified information about that element.
It is used as an inline element like span, sometimes with class tooltip text. One can set a position to that tool tipped text by using CSS, which helps us to define some style and position to our tooltip. Using a tooltip to our WebPages is helps us do more interaction with the user because it gives short information of included elements.
Syntax
HTML uses a method that defines tooltip by using the link with a title attribute. It can define as follows:
<a href=”” title=”tooltip_text”> Content </a>
As shown in the above syntax, the text displayed in the title attribute is considered as tool tipped text. So users can click this link to see more information about it.
The title is considered as a global attribute, so it allows the user to easily add it to the element, which is as simple as adding a class or id to the element. With the help of that, one can add simply anything means paragraph, div block, which is containing whole column and many more things. Basically, a tooltip is shown top of the element. One can put their tooltip at the position like top, bottom, left or right. This position to their tooltip by using some value defined in CSS.
