Managing dimensions (width and height) of HTML elements is a crucial aspect of creating dynamic, responsive web applications. jQuery provides a straightforward way to handle these properties, making it easier for developers to manipulate element sizes programmatically.
Managing the dimensions of HTML elements is essential for responsive design, ensuring that elements adapt correctly to different screen sizes and orientations. jQuery offers methods to get and set the width and height of elements, making it easy to dynamically adjust the layout of your web page.

jQuery provides methods to get the width and height of elements.
width()
The .width()
method gets the current computed width of the first element in the set of matched elements.
Get Width Example
#box
element is retrieved and displayed in an alert box.#box
element, which is 200px.height()
The .height()
method gets the current computed height of the first element in the set of matched elements.
Get Height Example
#box
element is retrieved and displayed in an alert box.#box
element, which is 100px.jQuery allows you to set the width and height of elements using the .width()
and .height()
methods.
.width(value)
The .width(value)
method sets the width of each element in the set of matched elements.
Set Width Example
#box
element is set to 300px.#box
element is 200px wide.#box
element’s width changes to 300px..height(value)
The .height(value)
method sets the height of each element in the set of matched elements.
Set Height Example
Explanation:
#box
element is set to 150px.Output:
#box
element is 100px tall.#box
element’s height changes to 150px.innerWidth()
The .innerWidth()
method gets the current computed width for the first element, including padding but not border.
Get Inner Width Example
#box
element is retrieved and displayed in an alert box.#box
element, which includes the width and padding, but not the border.outerWidth(includeMargin)
The .outerWidth(includeMargin)
method gets the current computed width for the first element, including padding and border, and optionally margin if includeMargin
is true
.
Get Outer Width Example
#box
element, including padding, border, and margin, is retrieved and displayed in an alert box.#box
element, which includes the width, padding, border, and margin.innerHeight()
The .innerHeight()
method gets the current computed height for the first element, including padding but not border.
Get Inner Height Example
#box
element is retrieved and displayed in an alert box.#box
element, which includes the height and padding, but not the border.outerHeight(includeMargin)
The .outerHeight(includeMargin)
method gets the current computed height for the first element, including padding and border, and optionally margin if includeMargin
is true
.
Get Outer Height Example
#box
element, including padding, border, and margin, is retrieved and displayed in an alert box.#box
element, which includes the height, padding, border, and margin.A responsive image gallery adjusts the dimensions of images to fit the screen size.
