Sample Files

These pages have been used at our meetings to demonstrate different HTML and CSS topics. Each page can be used to experiment with a particular tag or technique. There are notes in the source. Download the pages and edit the source to see how the styles work.

Each of these documents opens in a new window.

For more recent samples, see the PACS CodePen site.

CSS Variables

CSS variable example
As of this date, CSS variables are only supported in Firefox starting in version 31. Save the sample file and turn the styles on and off to see the difference in styling when using a variable.


This sample from October 2013 demonstrates the use of :first-child to fix a problem with the margin at the top of a page. Save the file to your computer and experiment with :first-child in the source. Also experiment with the column-count and column-gap styles.

The Box Model

Basic Boxes
The source of this document has a number of CSS rules that illustrate some basics of styling boxed. Try the width declarations in both Internet Explorer and Firefox to see the different interpretations of how “width” is rendered.
