An introduction to how css can be used internal css to change style in a single webpages to external css to apply to whole websites. Simple explanation with source code and a style switcher - A CV page to show -off tech skills containing a clock animation created using flash actionscript and an iPhone with scrollable screen and interactive buttons using Javascript to allow users to switch styles to plain print view styled page. Shows why Cascading Style sheets are so important. Another example to show how websites can allow users to switch between large and small text. Excellent visual way to explain why websites must allow the user to customise websites in terms of colours, size of text, background images etc, or risk discriminating / isolating users using Cascading Stylesheets. Can be used for all levels.

This is a difficult subject often briefly covered by having classes share some variables. These resources will help students understand the advantages of using classes with lots of practical activities.

Resources for GCSE Computing course for the Data Representation topic. The Resource explains how different data is stored, so introducing data types and variables and shows how important it is to make sure the correct variables are selected by the programmer. Uses examples in Python and an excel program ( input form and vba coding) has been created for students to investigate for themselves, what can go if wrong data types for variables are chosen by the programmer. Overflow error, type Mismatch, rounding up errors, Validation etc.
