what is the difference between<big>and<bold>

Answer 1

There's no 'bold' tag but <b> is. It marks text as bold but should be used as a last resort. For important text use <strong>. Or use CSS "font-weight" for bold text.
<big> is not supported in HTML5! It defines bigger text. Not bold but bigger. Use CSS "font-size".

Answer 2

<big> is used to make the text look bigger in size that is font is large. <bold> is used to darken the text implies to say that the text is important.

Answer 3

@Neelakanta uppvoting your own incorrect answer (and dowvoting correct ones) doesn't make it correct. There's NO <bold> tag!
