Question

Html minor problems pls help

Answer 1

you can ignore the value I think you don't need value for check box but (female) you have to write before input or after you close it like this :

female <input type="checkbox" name="aaa" />

or

<input type="checkbox" name="aaa" /> female

Answer 2

and what about radio?
do i need value for that?
and please tell me what is the main role of value and name?

Answer 3

also radio hasn't value and for main role I don't know if there is mine role but I think you will write the value according the attributes
