-## Ink overflow and scrollable overflow
+CSS overflow happens when the content of a box extends past one or more of the box's edges. **Scrollable overflow** is content that appears outside of the box for which scrolling mechanisms need to be provided. The overflow properties are how we can control what happens when content overflows a box.
 
-There are two types of overflow that you might encounter in CSS. The first is described as **ink overflow**. This is the overflow of painting effects which do not affect layout or otherwise extend the scrollable overflow region, such as box shadows, border images, text decoration, overhanging glyphs, outlines, etc.
+Painting effects that overflow content but do not participate in the CSS box model, also known as {{Glossary("ink overflow")}}, do not affect layout. Ink overflows, such as box shadows, border images, text decoration, overhanging glyphs, outlines, etc., do not extend the scrollable overflow region.
 
-The overflow that we sometimes need to manage in CSS is described as **scrollable overflow**. This is the content appearing outside of the box for which scrolling mechanisms need to be provided. The overflow properties are how we can control what happens when content overflows a box.
+## Overflow in action
 
-## Basic example
+The following interactive example shows the effects of changing the value of the `overflow` property changes overflow of a fixed-size box. The example also includes options to change the `width` and `overflow-clip-margin` property values, as well as to programmatically scroll the content if the overflow property creates a {{Glossary("scroll container")}}.
 
-The following interactive example shows how changing the value of the `overflow` property, changes how the overflow of a fixed height box is dealt with.

+A link is included in the preformatted lyrics to demonstrate the effects of keyboard focus on overflow and scroll behaviors. Try tabbing to the link or programmatically scrolling the content: the content will only scroll if the enumerated `<overflow>` value created a scroll container.
