CSS Images is a module of CSS Style that defines what types of images can be used on a web page as: the type, containing URLs, gradients and other types of images and how to resize images, and other replaced content, interact with the different layout models.

We can add image size CSS Style as:
Inline - by using the style attribute in HTML elements
Internal - by using a <style> element in the <head> section
External - by using an external CSS Style file as style.css

Inline CSS and HTML Syntax:

<img style = "property:value" src = "image_link" />

Internal CSS and HTML Syntax:

<html>
<style>
.selector_name { property: value; }
</style>
<body>
<img class = "selector_name" src = "image_link" />
</body>
<html>

by using an external CSS Style file as style.css where we add CSS Style .selector_name { property: value; }

External CSS and HTML Syntax:

Note: use external CSS instead.

CSS image size

Receptive images refer to images that fit the different dimensions of the container, box, or screen, resolutions, positions, and other factors.
Since most websites are now responsive, you should avoid adding static images to your pages.

In the following example we show you two methods to represent an image on the web page

Inline - by using the style attribute in HTML elements
Internal - by using a <style> element in the <head> section

For a better understanding we present an example:

Example (this is HTML - PHP editor, change text, values on this window)

<!DOCTYPE html>

  <html>

  <head>

  <title>CSS image size - example</title>

  <style>

  .pic{

  height: 250px;

  width: 220px;

  }

  </style>

  </head>

  <body>
<h2>CSS image size</h2>

  <img style="width:220px; height:240px; margin-right:16px"

  src="https://www.agernic.com/templates/mariwel.jpg"

  alt="news templates"/><img class = "pic"

How do I resize images

We can resize an image by specifying the width and height of an image as shown in the above example.
Another solution is to use the max-width: 100%; and height: auto; so that large images do not exceed the width of their container where is fit it.
The max-width and max-height properties of CSS works better, but sometimes they are not supported in many browsers.
Another way of resizing the image is using object-fit property, which fits the image proper. This CSS property specifies how a video or an image is resized to fit its container or div.
In this example, we are resizing the image from above example by using the max-width: 100%; and height: auto; properties.

Example (this is HTML - PHP editor, change text on this window)

<!DOCTYPE html>

<html>

<head>

<title>CSS image resize - example</title>

<style>
div { 

  width: 200px; 

  text-align: center; 

  padding: 10px; 

  border: 2px solid red; 
} 

  img { 

  max-width: 100%; 

  height: auto; 

  } 
 </style>

  </head>

  <body>
<h2>CSS image resize</h2>

  <div>

  alt="news templates" />

  </div>

  </body>

  </html>

Note: This property max-width is not supported in many browsers.

In this example, we are using the object-fit: cover; property.

cover value

The cover value specifies that the background image must be sized so that when resizing the container, box, or div, it covers the entire surface.

<!DOCTYPE html>

  <html>

  <head>

  <title>CSS image resize object-fit: cover; property</title>

  <style>

  .big_size_cover {

  background-image: url(https://www.agernic.com/images/css-background-image-size-fit-full-screen-final.jpg);

  background-size: cover;

  width: 260px;

  color: pink;

  resize: both;

  overflow: scroll;

<h2>CSS background image size to fit screen</h2>
