Is the end tag </img> necessary for the <img> tag?
Not in html5. Other tags not needing closure include input, br, hr, meta for example.
if u use its good for you
No it's not as we write <img /> This "/" works as a closer We don't need </img> because all this tags and reference id's are written within <img/> tag like < img scr=" " alt=" " coords=" " />
no its not.
