Get tired searching animations for your menu items and links? Search no more! Here is a list of more than 100 different animations. From the simple one to the more complex one, you will for sure find what you want.

No SVG, No JS, No extra tag, No pseudo element, No keyframes ... All of them are done using backgrounds, transition and only one element. Simply add a class and enjoy.

In order to understand the logic of each animation, I highly recommend my article about background-position

Few notes:

  • currentColor will use the color defined inside color.
  • I am using CSS variables to make the code shorter. var(--d, 0) means that the default value is 0 then I change it on hover.
  • The syntax 0 100% /var(--d, 0) 3px means background-position / background-size. We adjust the 3px to control the height/thickness of the line.

(2) and (5) use some hardcoded values that need to be adjusted based on the element width

The Inverted

The below doesn't work on Firefox due to a known bug

The 3D

Warning: the below uses some advanced CSS but I considered CSS variables to make it easy to control


That's it!
