Q: Hover Effect Ideas I'm using a development named "Hover Effect Ideas" (Warm Oscar) available on internet, the purpose of which is to add an effect to hovering an image :

I have titles  sometimes on one line and sometimes on two lines.
I'm having trouble aligning these titles like this :
Alignement of titles
When there are two or more text lines, the titles are shifted.
CSS is not for me! Can you help me please ?

A: The h2 is initially offset from the top using transform: translate3d(0, 100%, 0).
This moves the element on the y axis, and is causing a different displacement depending on the overall height of the element (I think).
You could transition the top value instead. To do this, add position: relative to the h2, and give it an initial value (top: 50px in the example below). On hover set top: 0.
