What's the meaning of nesting,,,,,,?!!,,and why must one use css for colours to appear or is html5 alone enough

Answer 1

Nesting is when you place something inside of something else.

EXAMPLE:

<div id="OuterDiv">
<div id="NestedDiv">
</div>
</div>

As for your other question, HTML is simply the STRUCTURE of your webpage and CSS is the STYLE (visual) of your webpage. So you'll want to learn CSS along with HTML, and then learn Javascript if you want functionality on the client-side. If you want databases or backend functionality, you'll want to then learn a server-side language such as NodeJS, PHP or ASP, then learn something like SQL/MYSQL/NOSQL in order to understand/create/alter/maintain databases.
