<frame src="a.htm"/>

Question

why only slash symbol is used at the end of instruction?

Answer 1

Because it doesn't have inner HTML (not necessary)

Answer 2

inner html is the e.g. Text between the opening and closing tag

Answer 3

and some element don't need this text between the tags so it makes no sense at all to make a closing tag, that's why there is this /> at the end which stands for the closing tag

Answer 4

thank you😊👍

Answer 5

I didn't get the meaning of inner html...can you explain ???
