This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the 兼容性表格 at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

image-orientation CSS property specifies a layout-independent correction to the orientation of an image. It should not be used for any other orientation adjustments; instead, the transform property should be used with the rotate <transform-function> .

警告： This property is deprecated in the specification. Its functionality may be moved into properties on the <img> and/or <picture> elements, with the possible exception of from-image 。 flip and <angle> values were made obsolete in Firefox 63.

/* keyword values */
image-orientation: none;
image-orientation: from-image; /* Use EXIF data from the image */
/* Global values */
image-orientation: inherit;
image-orientation: initial;
image-orientation: unset;
/* Obsolete Values. Obsolete since Gecko 63 */
image-orientation: 90deg; /* Rotate 90deg */
image-orientation: 90deg flip; /* Rotate 90deg, and flip it horizontally */
image-orientation: flip; /* No rotation, only applies a horizontal flip */
					

句法

值

none

Does not apply any additional image rotation; the image is oriented as encoded or as other CSS property values dictate.

from-image

Default initial value. The EXIF information contained in the image is used to rotate the image appropriately.

<angle> Obsolete since Gecko 63

<angle> of rotation to apply to the image. It is rounded to the nearest 90deg ( 0.25turn ).

flip Obsolete since Gecko 63

The image is flipped horizontally (i.e., reflected) after the rotation given by the <angle> value is applied. If no <angle> is given, 0deg 被使用。

描述

This property is intended only to be used for the purpose of correcting the orientation of images which were shot with the camera rotated. It should not be used for arbitrary rotations. For any purpose other than correcting an image's orientation due to how it was shot or scanned, use a transform property with the rotate keyword to specify rotation. This includes any user-directed changes to the orientation of the image, or changes required for printing in portrait versus landscape orientation.

If used in conjunction with other CSS properties, such as a <transform-function> , any image-orientation rotation is applied before any other transformations.
