This article is about how to use CSS to stretch and zoom an image in the background. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

You can use only CSS to stretch and scale the image in the background using CSSbackground-size: cover;. In this way, the image is scaled as large as possible so that the background area is completely covered by the background image while retaining its inherent aspect ratio.

However, if the width or height of the adjusted background image is too large relative to the element, part of the image may not be visible (vertically or horizontally).

Let's try the following example to understand the basic operation of this property:

Try this code for example »

Stretch and Scale Background-image with CSS

.box {

Width: 300px

Height: 300px

Background: url ("images/avatar.svg") no-repeat

Background-size: cover

Border: 6px solid # 333

Margin: 20px

}
