@camperextraordinaire i will be really grateful if you find some time ans teach me how do I shorten this jquery.
And why am i facing problems while trying to change classes using javascript instead of jquery .the code
@Lelouch it’s happening exactly as I want, but if possible, I want to know a shorter way to do it.
and I searched for the way to use javascript to change CSS classes, using class list , or something close, but it did not work.
