Chapter 21 - Web Authoring


Web Development Layers

A website is a collection of individual web pages which are related to each other. In a web page, there are three main layers that we can see.
  • Content Layer - With HTML
  • Presentation Layer - With CSS
  • Behaviour Layer - With Java Script

Getting Started 

You can use WYSIWYG editor or notepad to create your webpages. I am here showing you how to use MS Sharepoint to create your webpage.

Tips

  • Always Create a separate folder for your HTML source code and all your required files to be saved.
  • Always save your HTML code with .HTML or .htm extension.
  • Always save your CSS code with .css extension.

Basic HTML structure 

All HTML web pages start with <!DOCTYPE HTML> declaration and all instruction are written by HTML markup language not any other Mark up. Most of the tags start with Open and closing Tags(<> & </>) and this structure has a head and a body which will have many other tags with attributes.

Preset Styles and comment tag

In the above picture, you can see in the source code comment tag and the comment is there but it's not visible to the user. 
It is acceptable to use capital letters in the text that is displayed on the page, but not in the HTML tags.

Tables in the content Layer

In this topic, I would like to take exam questions as an example, therefore I can focus and point out the important points which you need to consider when you answer Paper 3.
