CSS transitions provide a way to control animation speed when changing CSS properties.
Instead of having property changes take effect immediately, you can cause the changes in a property to take place over a period of time. For example, if you change the color of an element from white to black, usually the change is instantaneous.

Normally you wouldn't specify this unless you needed to override a positioning that had been previously set. 2. position:relative If you specify position:relative, then you can use top or bottom, and left or right to move the element relative to where it would normally occur in the document.
Let's move div-1 down 20 pixels, and to the left 40 pixels: Notice the space where div-1 normally would have been if we had not moved it: now it is an empty space.
