What's the difference between <ins>and <u>? both produces the same output

Html

Answer 1

I have just checked on w3schools, <ins> is apparently when you insert something into a document. Not underline.

Answer 2

Here's some important information:
<b> and <strong> makes text bold
<i> and <em> makes text italic
<u> and <ins> makes text underlined
<Del >and <s> both strike through text

The difference is that <ins> has a semantic meaning while <u> is just styling one like the difference between <em> and <i>
