In the skeleton.css file, at line 301:
.container:after {
clear: both;
content: " ";
display: block;
height: 0;
visibility: hidden;
}
By including this declaration, any content that appears after the container will remain hidden, ensuring that the grid layout of the page is not disrupted in any way.
The container is defined as 960px wide and set to position:relative
(as per line 24 of skeleton.css), meaning that trying to create elements within the container that span the entire page width without using javascript (or jQuery) may pose a challenge. This is a crucial design aspect for most websites, and it's not advisable to rely solely on this method.
To test the impact on the grid layout, consider removing the :after declaration on .container and instead adding a new <div>
below with width:100%; height:128px;
as a starting point.
