Css Transition For My Home Made Nav - css

Question

I have created a nav menu myself for my website, I'm no expert but I think the menu turned out great ... I would like for my the menus to open a little slower then instant, maybe have a .5s transition ... I have tried to implement myself but I just don't seem to be able to figure it out .... I have created a jsfiddle to show my nav bar ... I was hoping to someone could show me how to had a transition to all the drop down menus if its possible ... Thank You

Answer 1

The problem is that transitions animate a property when that property changes. For example, if I had a div that was 100px wide, then added a class to it that switched it to be 300px wide, you could set transition: width 3s and it would grow over that 3 second period.
In your case, all that's changing is display:block / display:hidden
To get it to transition, you'll need to change things so that, rather than hiding it with display:hidden, you're hiding it by shrinking it to be really tiny and growing, or changing the opacity, etc.
