I am looking to add a fixed position button on my website, which can either be displayed on the left-hand side or appear as a popout panel similar to what is seen on where there is a cool popout button at the bottom of the screen. When this button is clicked, it will trigger a popup window that contains important contact and feedback information for my company.
Can anyone provide me with a simple CSS example for creating these types of buttons? I have successfully created the popup window using JavaScript, but I lack the necessary CSS skills to make the button activate the window.
