Centering Images
With CSS, you can center images with several methods.
An image can be centered horizontally, vertically, or both.
Center an Image Horizontally
To display a horizontally centered image, we can use margin: auto; or display: flex;.
1. Using margin: auto
One way to center an image horizontally on a page is to use margin: auto.
Since the element is an inline element by default (and
margin: auto does not have any effect on inline elements) we must convert the image to a block element, with display: block.
In addition, we have to define a width. The width of the image must be smaller than the width of the page.
Here is a horizontally centered image using margin: auto:
Example
img {
display: block;
margin: auto;
width: 50%;
}
2. Using display: flex
Another way to center an image horizontally on a page is to use display: flex.
Here, we put the element inside a
We add the following CSS to the div container:
display: flexjustify-content: center(centers the image horizontally in the div container)
Then, we set a width for the image. The width of the image must be smaller than the width of the page.
Here is a horizontally centered image using display: flex:
Example
div {
display: flex;
justify-content: center;
}
img {
width: 50%;
}
Vertical and Horizontal Centering
To display an image that is both vertically and horizontally centered (true centering), we can use display: flex; or display: grid;.
1. Using display: flex
To display an image that is both vertically and horizontally centered with flexbox, we use a combination of:
display: flex;justify-content: center;(centers the image horizontally in the container)align-items: center;(centers the image vertically in the container)height: 600px;(the height of the container)
Here, we also put the element inside a
Then, we set a width for the image (must be smaller than the width of the container).
Here is a vertically and horizontally centered image with flexbox:
Example
div {
display: flex;
justify-content: center;
align-items: center;
height: 600px;
border: 1px solid
black;
}
img {
width: 50%;
}
2. Using display: grid
To display an image that is both vertically and horizontally centered with grid, we use a combination of:
display: grid;place-items: center;(centers the image horizontally and vertically in the container)height: 600px;(the height of the container)
Here, we also put the element inside a
Then, we set a width for the image (must be smaller than the width of the container).
Here is a vertically and horizontally centered image with grid:
Example
div {
display: grid;
place-items: center;
height:
600px;
border: 1px solid
black;
}
img {
width: 50%;
}
