Thank you very much However, the transition to open the menu is still very abrupt. I would like it to slide open more slowly and smoothly.

I am using the W3S responsive top menu but the transition to open the mobile menu is not smooth. I'm good with css but my skills with JS are lacking. Can someone please advise the code to make the transition slide open? This is the current JS: <script> function myFunction() { var x = document.getElementByld("myTopnav"); if (x.className === "topnav") { x.className += "responsive"; } else { x.className = "topnav"; } } </script> Any help gratefully received. Thanks
