How to realize automatic rotation of 90 degrees in html

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)

}
