Our websites will be ‘hosted’ on a bathspa server
FTP

8. HTML ELEMENTS AND TAGS
ELEMENTS
Individual component of a webpage
e.g. image, video, text paragraphs, sound, headers, tables
TAGS
HTML markup that represents or describes an elements
<img>, <video>, <p>, <audio>, <h1>, <table>
Tags must be opened and closed
<p> Hello World </p>

9. WEBPAGE ESSENTIALS
A series of tags to set up a web page
Save as a template!
<!DOCTYPE html>
<html>
These two tags tell the browser that the file is a HTML document
<head>
Contains a collection of metadata for the document. Metadata is
data about data.
This includes page titles, and links to CSS and JavaScript documents
<meta charset=“UTF-8”>
Character set that should be used to render the web page
<title>
Gives the webpage a title. Title shown in browser toolbar and in
web searches
<body>
Content of the webpage itself
10. BODY TAGS<header>
Headings
<nav>
Navigational sections. Links to pages on the website
<section>
Thematically grouped content
<article>
An article e.g. blog post or comment section
<aside>
Content placed aside. Should be related to surrounding
content (section/article)
<footer>
Usually placed at the end of a document e.g. contact
information
<div>
A general container for content
<p>
Paragraph. Almost always used for text
A VERY stereotypical webpage

Editor's Notes
Can use sound but be aware that the module is about interactive text, so its important to demonstrate an interactive approach to text.
Javascript: So we could write some javascript that changes the colour of some text when it is clicked on Libraries: Prewritten javascript that simplifies the scripting process. Instead of writing long passages of javascript to say, spin some text, you can find a library that reduces this down to about one line. A very good one is jQuery. We will be using that when we look at interactivity using javascript. Jquery: javascript library that simplifies the scripting process. A good introduction to javascript. We will be using this.Other: we won’t be using them but its useful to know there are lots of other toolsPHP server side scripting language – communicating with servers (looking up data in a database)MYSQL – database management
