CSS Background Image

CSS background image is a property that allows you to add a background image to an element on a webpage. With the various background image properties available in CSS, you can customize the size, position, and repetition of your background images, blend them with other background images or colors, and even adjust their opacity. By using CSS background images strategically and creatively, you can enhance the user experience of your website or web application, communicate your brand identity, and convey your message effectively.


The syntax for the CSS background-image property is:

selector {
  background-image: url('path/to/image.png');
}

Example:

<!DOCTYPE html>
<html>
<head>
  <title>Background Image Example</title>
  <style>
    body {
      background-image: url("https://static.wixstatic.com/media/0f65e1_80dc6da5a5534d04a00317be47e95525~mv2.jpg");
      background-repeat: no-repeat;
      background-size: cover;
    }
  </style>
</head>
<body>
    <h2>This is an example of CSS Background Image</h2>
</body>
</html>

Output:

In this example, we set the background-image property to the URL of the image we want to use as the background. We also set the background-repeat property to no-repeat, which means the image will only be displayed once and not repeated. We set the background-size property to cover, which means the image will cover the entire background of the page, even if it needs to be stretched or cropped to fit.


Background Image Properties

Here are some of the most commonly used properties related to background images:


1. background-repeat:

This property controls how the background image is repeated. The possible values are repeat, repeat-x, repeat-y, and no-repeat. For example:

background-repeat: no-repeat;

Example:

With repeat property

<!DOCTYPE html>
<html>
<head>
  <title>Background Image Example</title>
  <style>
    body {
      background-image: url("https://static.wixstatic.com/media/0f65e1_80dc6da5a5534d04a00317be47e95525~mv2.jpg");
      background-repeat: no-repeat;
    }
  </style>
</head>
<body>
    <h2>This is an example of CSS Background Image</h2>
</body>
</html>

Without repeat property

<!DOCTYPE html>
<html>
<head>
  <title>Background Image Example</title>
  <style>
    body {
      background-image: url("https://static.wixstatic.com/media/0f65e1_80dc6da5a5534d04a00317be47e95525~mv2.jpg");
     
    }
  </style>
</head>
<body>
    <h2>This is an example of CSS Background Image</h2>
</body>
</html>


2. background-position:

This property sets the starting position of the background image. You can use keywords like top, left, center, or you can use pixel or percentage values. For example:

background-position: center;
background-position: 50% 50%;

Example:
<!DOCTYPE html>
<html>
<head>
  <title>Background Image Example</title>
  <style>
    body {
      background-image: url("https://static.wixstatic.com/media/0f65e1_80dc6da5a5534d04a00317be47e95525~mv2.jpg");
      background-position: center;
    }
  </style>
</head>
<body>
    <h2>This is an example of CSS Background Image</h2>
</body>
</html>



3. background-size:

This property sets the size of the background image. You can use a fixed size, like this:

background-size: 200px 150px;

Example:

In this example, i am using only background-size property and i am not using background-repeat property. If you are not using background-repeat property, then the image will be repeated and will be displayed all over the page.


If you don't want to repeat the image, then add "background-repeat: no-repeat;" in the below code.

<!DOCTYPE html>
<html>
<head>
  <title>Background Image Example</title>
  <style>
    body {
      background-image: url("https://static.wixstatic.com/media/0f65e1_80dc6da5a5534d04a00317be47e95525~mv2.jpg");  
      background-size: 200px 150px;
    }
  </style>
</head>
<body>
    <h2>This is an example of CSS Background Image</h2>
</body>
</html>


Or you can use the cover or contain keywords, like this:

background-size: cover;
background-size: contain;

4. background-attachment:

This property controls whether the background image scrolls with the rest of the content or stays fixed in place. The possible values are scroll (default) and fixed. For example:

background-attachment: fixed;

Example:

In the below code, you will see that the image is fixed. If you scroll down, only the text is moving.

<!DOCTYPE html>
<html>
<head>
  <title>Background Image Example</title>
  <style>
    body {
      background-image: url("https://static.wixstatic.com/media/0f65e1_80dc6da5a5534d04a00317be47e95525~mv2.jpg");
      background-repeat:  no-repeat;
      background-size: cover;
      background-attachment: fixed;
      color: white;  //font color is white
    }
  </style>
</head>
