Summary  
This chapter explains how display types—block, inline, and inline-block—govern element layout behaviors (line breaking and width) and which CSS properties (like width, height, margin, and padding) can be applied.  

General domain of usage  
Web development

HTML elements behave differently depending on whether they are **block**, **inline**, or **inline-block**. These display types affect layout, spacing, and what CSS properties you can use.

## Block Elements 
- Start on a **new line**;
- Take up the **full width** of their container;
- Support width, height, margin, padding, and border.

Common examples: `<div>`, `<p>`, `<ul>`, `<li>`, `<h1>–<h6>`.

## Inline Elements
- Stay **on the same line**;
- Take only the **space needed for their content**;
- Cannot have width or height applied (but border works).

Common examples: `<a>`, `<span>`, `<img>`, `<input>`.

## Inline-block Elements
- Stay **inline**, like text;
- Support **width**, **height**, **margin**, **padding**, and **border**, like block elements.

Examples: `<button>`, `<select>`, `<textarea>`.

They are useful when you need elements to sit side by side, but still allow full styling control.
