🙋 Introduction

The width property in CSS is used to set the width of an element. This property can be applied to various HTML elements including divs, images, tables, and more.

By specifying the width, you can control how much horizontal space an element should occupy on the page, making it a fundamental tool for layout design in web development.

💡 Syntax

The syntax for the width property is simple and straightforward. You can specify the width using various units such as pixels, percentages, ems, and more.

Syntax

Copied

element {
  width: value;
}

Here, value can be a length (e.g., 100px, 50%, 10em), or the keywords auto, max-content, min-content, fit-content, or inherit.

🎛️ Default Value

The default value of the width property is auto. When set to auto, the width of the element is determined by the content inside it or by the default styling of the browser.

🏠 Property Values

Value	Description
length	Specifies a width value in units such as pixels (px), ems (em), rems (rem), etc.
percentage	Specifies a width value as a percentage of the containing element's width.
auto	The browser calculates the width.
max-content	The intrinsic preferred width.
min-content	The intrinsic minimum width.
fit-content	The maximum available width.
inherit	Inherits the width value from the parent element.

📄 Example

In this example, we'll set the width of a div element to 200 pixels.
