How to make Jquery click smoother

Question

I'm trying to make a side-menu from scratch. I finished it, but how can I make the animation smoother? I would also like to get rid of the blue background when you click the button without changing the other elements

Answer 1

You can change the css via animate instead of .css, example
.animate({

left: "0",

}, 500, function() {

// Animation complete.

});
