CSS Cubic Bezier Generator
The CSS Cubic Bezier Generator will help you visualize how an transition is going to look. You can adjust the bezier curve my dragging the handles on the graph below, or, enter specific numbers into the cubic-bezier function. Once you've selected the perfect numbers, hit 'Compare Transitions' and this will show you how your transition compares to a few other popular transitions. Alter the speed and display for a different appearance. At the completion of the transition, just wait 1 second and you will see the animation in reverse.
