+###Animation-Keyframes
+
+Animation-keyframes are provided for quick out-of-the-box animations. Two animation-keyframes are provided: fade-in, fade-out. These animations can be called using the *animation-name* mixin; alternatively the *animation-basic* mixin can be used. Supports Webkit browsers and Mozilla 5.0+.
+
+    div.fade-in {
+      @include animation-name(fade-in);
+    }
+
+    div.fade-out {
+      @include animation-basic(fade-out, 2.0s, ease-in);
+      opacity: 0;
+    }

+The button add-on provides well-designed buttons with a single line in your CSS.  
+The mixin supports a style parameter and an optional color argument. The available styles are **"simple"** (default), **"shiny"**, and **"pill"**.
 
-    button,
-    input[type="button"] {

-The mixin supports a style parameter. Right now the available styles are "simple" (default), "shiny", and "pill".

-    input[type="button"] {
+    # Pass a style argument
+    button, input[type="button"] {
       @include button(shiny);
     }
 
-The real power of the mixin is revealed when you pass in the optional color argument. Using a single color, the mixin calculates the gradient, borders, box shadow, text shadow and text color of the button. The mixin will change the text to be light when on a dark background, and dark when on a light background.
