image-orientation

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

Summary

The image-orientation CSS property describes how to correct the default orientation of an image.

Note:

This property is not intended to perform arbitrary rotation on an image, but to correct erroneous orientation. That's why it is rounded to the nearest quarter of a turn.
Similarly this property is not intended to handle the layout -> portrait changing. As image-orientation affects only images, it won't work: the changes must happen at the layout-level.

Initial value	`0deg`
Applies to	all elements
Inherited	yes
Media	visual
Computed value	an `<angle>`, rounded to the next quarter turn from `0deg` and normalized, that is moduloing the value by `1turn`
Animatable	no
Canonical order	the unique non-ambiguous order defined by the formal grammar

Syntax

image-orientation: 0deg;
image-orientation: 6.4deg;     /* Rounded to 0deg */
image-orientation: -90deg;     /* Equivalent to 270deg, its normalized computed value */
image-orientation: from-image; /* Use EXIF data from the image */
image-orientation: 90deg flip; /* Rotate 90deg, and flip it horizontally */
image-orientation: flip;       /* No rotation, only applies a horizontal flip */

/* Global values */
image-orientation: inherit;
image-orientation: initial;
image-orientation: unset;

Values

from-image: The EXIF information contained in the image will be used to rotate the image appropriately.
<angle>: The <angle> of rotation to apply to the image. It is rounded to the nearest 90deg (0.25turn).
flip: The image is flipped horizontally, that is reflected, after the rotation given by the <angle> value. If no <angle> is given, 0deg is used.

Formal syntax

from-image | <angle> | [<angle>? flip]
