<section>

Question

whats is the use of section in article? whats the differnce while runing the code, lil confused.
If we uses only section then also no difference,while running replacing it,then too no difference.

Answer 1

Section is just a semantic div. Semantic, roughly speaking in this context, means it is supposed to indicate something special above and beyond its use for stylistic purposes. It is claimed that search engines look for this, but since search engine algorithms are proprietary, it's really anyone's guess.
