Use id attributes whenever you need to address a particular HTML element with CSS, JavaScript or a fragment identifier. It's possible to look up elements by name, too, but it's simpler and more reliable to look them up by ID.

Answer 2

id attribute :

id attribute uniquely represents an element. The element represented can be accessed via CSS or JS , to perform specific editing on the element. for example :-
css :
#name {
color: red;
}
This css code block access an element with an id name (that is - <div id="name">…</div>)and changes its color to red.

JS :
var a= document. getElementById("name");

This JS code block also access an element with an id name (that is - <div id="name">…</div>).

Event attributes :
an event attribute specifies what should happen when a particular event occurs, by event we mean any action such as clicking an element or placing the mouse on that element etc.
Please note that -

Example :
<div onclick=" alert('Hello') "></div>
Here onClick ( meaning - on click ) is an event attribute and the event or action is clicking the element.
This div element when clicked will show a prompt message "Hello".

I am sorry for the complex language. I hope its quite clear thanks.
