2. Href
3. Coords
4. Br

Q5. We can display the screen coordinates of the most recent touch by defining div at the ______.

1. top

we add some JavaScript to register the event listener, and add a handler function to do something with the touch data:

In the touchHandler function we grab the x and y coordinates of the touch, and write them to the coords div:

We also define a div at the top where we will display the screen coordinates of the most recent touch.

To handle the mouse events, touch events and pen events we have to write the code separately for each of these.

Microsoft made a standards proposal that reconciles touch events and mouse events and pen input too, into one model called pointer events.

While the Touch Events API was defined in terms of Touches, the Pointer Events API is defined in terms of Pointers,

While the Touch Events API was defined in terms of Touches, the Pointer Events API is defined in terms of Pointers,

Pointer is defined as: A hardware agnostic representation of input devices that can target a specific coordinate on a scree

lostpointercapture when element loses pointer capture

It refers to a JavaScript library that implements an HTML5 web standard

while entering data it should be clearly visible. It is much difficult to enter the small font data.
