I have this navbar but when it opens to show the content, I want it to open smoothly (With Transition) but it won't work.

Here is the example:

/* Google Fonts Import Link */
@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300;400;500;600;700&display=swap');
*{

As you can see it looks and functions fine but then it needs a smooth transition once the arrow is clicked.

I tried the simple transition: 0.5s; but it does not seem to work.

I was hoping someone could help me out or spot my mistake.

  • you are already including jquery, you should use "toggle" function, that includes the duration. – Alex Angelico Jun 15 '22 at 16:57
  • You cannot add a transitions to display properties. Check out the answers on here, the main solutions around this is to use opacity and height https://stackoverflow.com/questions/3331353/transitions-on-the-css-display-property – Parit Sawjani Jun 15 '22 at 17:04
  • The **display** css property can't be animated. – Anton Jun 15 '22 at 19:15
