People are starting to ask: where can I learn about CSS Grid?

There are a lot of fantastic resources out there. When it comes to the technical how-to, most of what’s out there was written by Rachel Andrew. If you don’t know her work, take some time to get to know her and follow her.

Today, we are in the early stages of such a revolutionary shift, brought about by CSS Grid Layout. Much of what we know of the possibilities, limitations and best practices surrounding web layouts is effectively rendered obsolete by this new layout module, and in their place we find new possibilities, limitations and best practices that will take us into the next era of web design.

In CSS, you have two techniques for visualizing change that are competing for your attention: Animations & Transitions. In this article, let's examine the similarities and differences between them so that you can know when to use which.

To make the most of this article, it would be helpful for you to be familiar with using both animations and transitions. If you haven't had a chance to get your hands dirty with them, the Creating a Simple CSS Animation and Looking at CSS3 Transitions tutorials will help you get started.

Use scale transforms when animating clips. You can prevent the children from being stretched and skewed during the animation by counter-scaling them.

Use 10% lighten and darken for hover/active states. Used the second darken for the button border
