What is the <base> element in HTML for? -

-

i learning how code on w3schools.com. there explanation on it's not helping. says "defines default address or default target links on page" why need this?

you don’t need base element. used when most urls on page refer site other site of page; in case, <base href="..."> lets use relative urls those; other urls must absolute. in past, <base target=...> used on frameset pages in order make link open in particular frame.
