Nav element in HTML - Browser Rendering Trace

Render Flow - Nav element

[Read <nav>] -> [Create NAV node] -> [Read child elements] -> [Create child nodes] -> [Add text or links] -> [Close child elements] -> [Close NAV]

The browser reads the <nav> tag, creates a navigation node in the DOM, then reads and adds its child elements like links, building a navigation section visually.

Render Steps - 3 Steps

Code Added:<nav> element with no children

Before

→

After

[ NAV ]
(empty space inside)

The browser creates a navigation container box but it is empty so nothing visible inside yet.

HTML

  <a href="#home">Home</a>
  <a href="#about">About</a>

</nav>

B Hidden from view

C Horizontally in a row

D Overlapping each other

Common Confusions - 2 Topics

Why doesn't the <nav> element look different from a <div> by default?

Because <nav> is a block container like <div> but has no default styling. It only adds semantic meaning for navigation.

💡 Use CSS to style <nav> visually; by default it looks like a plain block.

Why are the links inside <nav> displayed horizontally instead of vertically?

Because <a> elements are inline by default, so they line up side by side inside the block <nav> container.

💡 Inline elements flow horizontally unless styled otherwise.
