If "required" & "disabled" are attributes of <form> element then why dont we use the format of attributes [name="value"] ?

Question

Why they are written as it is without name and quotation marks.....

Answer 1

Because writing this:
<input type="text" disabled/>

is just the same as this:
<input type="text" disabled="true" />
Default 👆

Answer 2

The value can be any string
Only the existence of the attribute makes it true.

<button disabled=”sololearn”>Button</button>

without any value the selector is just the attribute

button[disabled]

Or in this case
button[disabled=”sololearn”]

Answer 3

You could write required="required", disabled="disabled"

Answer 4

I assume that if name and value are same we can write value itself

Answer 5

You're right

Answer 6

Is it [disabled="true"] or [disabled="disabled"] ?

Answer 7

it's got to be something
