Question

我有一个背景的跨度，我希望在不丢失收音机的情况下调整图像大小。我的意思是不伸展。当我使用height：auto;

时，我的图像消失了

#logo_span{
  display: inline;
  background-image: url("../gfx/hs_logo.png");
  margin: -5px auto auto -100%; /* margin top right bottom left */
  background-size: 50% 50%;
  background-repeat: no-repeat;
  width: 90%;
  height: auto;
}

Answer 1

如果您希望自适应图片使用public class Controller { @FXML private TextField txtField; @FXML private PasswordField passField; @FXML private Button btn; @FXML private Label access; private String USNM = "crimsoncoder"; private String PASS = "toor"; private static final String ACCESS_GRANTED = "/ACCESS_GRANTED/"; private static final String ACCESS_DENIED = "|/?ACCESS_DENIED?/|"; public void onClick() { String usnm = txtField.getText(); String pass = passField.getText(); if (usnm.equals(USNM)) { if (pass.equals(PASS)) { access.setText(ACCESS_GRANTED); } else { access.setText(ACCESS_DENIED); } } else { access.setText(ACCESS_DENIED); } } }代码而不是css <img/>。然后在css中使用background-image

当我使用CSS自动属性时，背景图像消失
