As for the rotation of the picture, there are generally 3 solutions: (1) filter (2) CSS3 (3) canvas. The next step is explained.For the convenience of understanding, we mainly explain in 90 degrees, taking into account other angles.1. Filter (ie exclusive)1.1 Rotate FilterThe syntax is as follows:Filter:progid:DXImageTransform.Microsoft.BasicImage (rotation=i);Rotation values 0 (0 or 360 degrees), 1 (90 degrees), 2 (180 degrees), 3 (270 degrees). The other number is invalid.Example of rotation 9
