problem description
the main reason is that in order to control the size of the placeholder, I added the class name to the img tag and deleted the class name after the picture was loaded, but there was a position: absolute location in the class name. After deletion, I don"t know why the inline style style= "display: inline," of the picture has become a big hand of style= display: block,.
