What is the difference between inline and block-level HTML elements?
❓ Interview Prompt: Compare block-level elements vs inline elements regarding default width, new lines, and nesting constraints.
HTML elements are divided into two primary formatting contexts by default:
1. Block-level Elements ('<div>', '<p>', '<h1>'-'<h6>', '<article>', '<section>')
•
Always start on a new line.
•
Occupy 100% of the parent container's width by default.
•
Can contain other block-level or inline elements.
•
Accept width, height, margin, and padding adjustments on all sides.
2. Inline Elements ('<span>', '<a>', '<strong>', '<em>', '<img>')
•
Do not start on a new line; flow along with text.
•
Occupy only as much width as their content requires.
•
Cannot contain block-level elements.
•
Top and bottom margins/paddings do not push surrounding block elements away.
Code Implementation Example
html
<!-- Block element occupies full width on new line -->
<div style="background: lightblue;">
Block Container
</div>
<!-- Inline elements flow horizontally -->
<p>
This is <span style="color: red;">inline text</span> inside a paragraph.
</p>💡Comparing block-level <div> layout vs inline <span> text flow.
🎯 Interview Key Takeaway
Block-level elements start on a new line and occupy 100% width; inline elements flow horizontally within content.
