Today, the editor will share with you the relevant knowledge points about how to achieve automatic rotation of 90 degrees in html. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

Under Firefox:-moz-transform:rotate (- 90deg)

-webkit-transform:rotate (- 90deg)

Under ie: filter:progid:DXImageTransform.Microsoft.BasicImage (rotation=3)

Here is the ie filter code part, in front of the long case intricacies of the part we do not care about it, look at the back of the "rotation=3" this is the key, here the parameters can be 0meme1meme2prime3, no 4, if it is 4 ah, 5 ah and so on, the picture will not rotate.

The angle of rotation can be multiplied by 90 (π / 2), so "rotation=3" means to rotate 270degrees clockwise, which is the same as transform:rotate (270deg). So, here, there will be some small limitations-you can't rotate at any angle, it can only be 90,180 and 270 degrees.

However, IE browser is not a simple Luo Luo, to achieve any angle of rotation, it still has a way, just more troublesome than the above, difficult to understand, to use the matrix transformation filter.

Demo is as follows:

Img {

Margin:100px auto 0

-moz-transform:rotate (- 90deg)

-webkit-transform:rotate (- 90deg)

Filter:progid:DXImageTransform.Microsoft.BasicImage (rotation=3)

}
