Use the <layer> tag in HTML to add a layer. The HTML <layer> tag is used to position and animate (through scripting) elements in a page. A layer can be thought of as a separate document that resides on top of the main one, all-existing within one window.
Example
You can try to run the following code to add a layer in HTML −
<!DOCTYPE html> <html> <head> <title>HTML layer Tag</title> </head> <body> <layer id = "layer1" top = "250" left = "50" width = "200" height = "200" bgcolor = "red"> <p>layer 1</p> </layer> <layer id = "layer2" top = "350" left = "150" width = "200" height = "200" bgcolor = "blue"> <p>layer 2</p> </layer> <layer id = "layer3" top = "450" left = "250" width = "200" height = "200" bgcolor = "green"> <p>layer 3</p> </layer> </body> </html>
