That removes the border. Doesn't affect bg color.

How many buttons? One or two? If you want to use only one button, let's closure it. Need to know default bg color for your border. Hard to give you specific answer if I can't see your html code. There are many tips and tricks to manipulate DOM.

<!DOCTYPE html> <html> <head> <title>Page Title</title> </head> <body> <p id="counter">0</p> <div id="demo">Hello World!</div> <button onclick="add()">Add/Hide Border</button> <script> function add() { var counter = document.getElementById("counter").innerHTML; counter++; document.getElementById("counter").innerHTML = counter; if (counter % 2 == 0) { document.getElementById("demo").style.borderColor = "white"; } else { document.getElementById("demo").style.borderColor = "red"; } } </script> </body> </html>
