Help me get the correct css to change please...

[Brian Jester]

I read your first post again and I think that if it's not my upper suggestion then you are definitely searching for these options:

Location 1: stellarnav.css
----------------------------
.stellarnav li a {
padding: 15px;
display: block;
text-decoration: none;
color: #777;
font-size: inherit;
font-family: inherit;
box-sizing: border-box;
-webkit-transition: all .3s ease-out;
-moz-transition: all .3s ease-out;
transition: all .3s ease-out;

-----------------------------------------------------
Location 2: stellarnav.min.css

.stellarnav li a {
padding: 15px;
display: block;
text-decoration: none;
color: #777;
font-size: inherit;
font-family: inherit;
box-sizing: border-box;
-webkit-transition: all .3s ease-out;
-moz-transition: all .3s ease-out;
transition: all .3s ease-out;

----------------------------------------------

Either you will want to play with the transition options or you could just simply delete the 3 last lines in the both files.
Tell me if I'd finally understood your wish

Thank you Aleksandar,

This was the solution, I removed the transition from both of the css files.

Thank you once again Aleksandar!
