How to set the background image to be centered in css

In CSS, you can set the center of the background image through the background-position attribute: horizontal values: center (center), left (left-aligned), right (right-aligned) vertical values: center (center), top ( Top alignment), bottom (bottom alignment) syntax: background-position: horizontal-value vertical-value;

How to use CSS to center the background image

Get straight to the point:

In CSS, use the background-position property to set the center position of the background image.

Detailed expansion:

background-position The property accepts two values, specifying the horizontal and vertical position respectively:

• Horizontal value:

  • center: Horizontally centered
  • left: Left aligned
  • right: Right aligned

• Vertical value:

  • center：Vertically centered
  • top：Top alignment
  • bottom：Bottom alignment

Grammar:

background-position: horizontal-value vertical-value;

Example:

body {
  background-image: url("background.jpg");
  background-position: center center;
}

Other notes:

• If a single value is specified, it applies to both horizontal and vertical positions.
• You can use a percentage value (relative to the size of the background image) or a length value (in pixels or em).
• You can also use the keywords initial and inherit to reset the value to the initial value or inherit the value of the parent element respectively.

Tip:

• When using percentage values, make sure the value does not cause the background image to extend beyond the bounds of the container.
• If the background image has a different aspect ratio than the container, use the background-size property to resize the image to prevent distortion.
