Different tag on HTML language but same function


Hey I just want to know because there no explanation on this site, to create BOLD and ITALIC word we are using tag "strong" and "em", but when I still student on highschool I am using tag "i" to create ITALIC and tag "b" to create BOLD word, I think it will easier to using this tag "i" and "b", can someone explain it?


I could, but someone wrote a brilliant answer for it, you can find it here.
