Remove 'Tap to call button'

Hi,

Can you let me know how to remove the tap to call feature please?

The code in the thread below doesn't seem to work

Many thanks!

 

Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

@media only screen and (max-width: 480px)
.header-info a.btn {
background: none;
margin-top: 0px;
margin-bottom: 0;
height: 0;
}
