It is the opposite of static HTML because you can interact with the web page content and the content changes as you interact with it.

For example…
When signing up to join Facebook you fill in a registration form and if you do not fill in all the details when you submit the form it will highlight all the form entries which you did not fill in.

CSS stands for Cascading Style Sheet which is used to describe the formatting of a document. These documents were written in a markup language such as HTML and XML.

What is it made up of?

CSS3 is the third version of CSS. Instead of defining all features in a single specification like in CSS3’s predecessor CSS2, CSS3 is divided into separate documents “modules”.

Examples of CSS3 tags

blockquote : Allows an author to specify the border-width, border-style, and border-color for all the borders of an element’s rendering box at once.

<blockquote style=”border: medium dashed #ff0000″>This is some text</blockquote>

border-bottom : specify the border-width, border-style, and border-color for the bottom border of an element.

<div style=”border-bottom: 10px outset #ffffff”>this is a test</div>

address : This property specifies whether the current element allows floated elements occurring earlier in the document to float along its sides. The values for this property indicate which sides of the element do not allow floating elements.

<address style="clear:both">some test</address>

caption : This property specifies the position of elements with an intrinsic (HTML CAPTION elements) or assigned ‘display’ property value of “table-caption” in relation to the table rendering box they are assigned to.

<caption style=”caption-side: right”>Caption</caption>

before: This property automatically generates content to attach before/after a CSS selector.

em:before { content: url(”ding.wav”) }
