Code Challange: floats 3 of 3

The question is "In the preview, notice how the floats made the parent container's height collapse. In the HTML file, give the .secondary-content div the specified class for clearing floats."

the css code is

.group:after {
 content: "";
 display: table;
 clear: both;
}

my edited html code is div class="group" with arrows around it and it errors Bummer! Make sure you're giving the 'secondary-content' div on line 9 the correct class for clearing floats.

Hi Ian,

Can't remember the challenge but can you try it with 2 semi colons please?

.group::after {
 content: "";
 display: table;
 clear: both;
}

This article from CSS Tricks may also help as a reference.

If that doesn't work can you post a link to the challenge please and I'll take a look? :)

I know this is 6 months old, but all you need to do is add group as a class to the <div> containing secondary-content

<div class="secondary-content t-border group">

The ::before and ::after pseudo-elements can be used to describe generated content before or after an element's content. It's effectively the same as the single-colon syntax defined by the level 2 spec. The level 3 spec introduces an extra colon to differentiate between pseudo-elements and pseudo-classes (which use a single colon).

Both syntaxes will work in newer browsers, but older browsers will not recognise the newer :: style.
