you don't see the pink without the overflow because the height of the father is zero.<br />
if you add this style to the father &quot;border: 2px solid red;&quot; you will see that.

Hi zc2, thanks for your quick comments. That's a good way to debug. So the question comes to be why with &quot;overflow:hidden&quot;, the outside box can be pushed bigger? Thanks!

This is a codepen <a href="http://codepen.io/condor05/pen/pjNOvo" rel="ugc">snippet</a>.<br />
<br />
With &quot;overflow:hidden&quot; being set for the div with class &quot;father&quot;, I can actually see the father CSS &quot;box&quot; with background color pink. However, if that is not set, I cannot see the father CSS &quot;box&quot;.<br />
<br />
So what does &quot;overflow:hidden&quot; used for in this scenario?

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.

Web Development

Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services using a wide variety of languages and standards, including the familiar HTML, JavaScript and jQuery, ASP and ASP.NET, PHP, ColdFusion, CSS, PHP, Flex and Flash, but also the implementation of a broad list of standards including XML, WSDL, SSDL, VoiceXML and many more.

Web Languages and Standards

HTML (HyperText Markup Language) is the main markup language for creating web pages and other information to be displayed in a web browser, providing both the structure and content for what is sent from a web server through the use of tags. The current implementation of the HTML specification is HTML5.
