HTML & Javascript

Chapter 2.HTML Text

Headings:

HTML___ has six “levels” of headings:

Bold & Italic: By enclosing words in the tags we can make characters appear bold.

By enclosing words in the tags can make characters appear italic.

TEXT Summary:

• HTML elements are used to describe the structure of the page (e.g. headings, subheadings, paragraphs).
• They also provide semantic information (e.g. where emphasis should be placed, the definition of any acronyms used, when given text is a quotation).

Chapter 10.Introducing CSS

CSS allows you to create rules that control the way that each individual box (and the contents of that box) is presented.

CSS Associates Style rules with HTML elements CSS works by associating rules with HTML elements. These rules govern how the content of specified elements should be displayed. A CSS rule contains two parts: a selector and a declaration.

CSS Properties Affect How Elements Are Displayed CSS declarations sit inside curly brackets and each is made up of two parts: a property and a value, separated by a colon. You can specify several properties in one declaration, each separated by a semi-colon.

Selector	Meaning	Example
Universal Selector	Applies to all elements in the document	* {} Targets all elements on the page
Class Selector	Matches an element whose class attribute has a value that matches the one specified after the period (or full stop) symbol	.note {} Targets any element whose class attribute has a value of note p.note {} Targets only <p> elements whose class attribute has a value of note
ID Selector	Matches an element whose id attribute has a value that matches the one specified after the pound or hash symbol	#introduction {} Targets the element whose id attribute has a value of introduction

INTRODUCING CSS Summary:

• CSS treats each HTML element as if it appears inside its own box and uses rules to indicate how that element should look.
• CSS treats each HTML element as if it appears inside its own box and uses rules to indicate how that element should look.
• Different types of selectors allow you to target your rules at different elements.
• Declarations are made up of two parts: the properties of the element that you want to change, and the values of those properties. For example, the font-family property sets the choice of font, and the value arial specifies Arial as the preferred typeface.
• CSS rules usually appear in a separate document, although they may appear within an HTML page.

JAVASCRIPT

Chapter 2. BASIC JAVASCRIPT INSTRUCTIONS

BASIC JAVASCRIPT INSTRUCTIONS summery:

• A script is made up of a series of statements. Each statement is like a step in a recipe.
• Scripts contain very precise instructions. For example, you might specify that a value must be remembered before creating a calculation using that value.
• Variables are used to temporarily store pieces of information used in the script.
• Arrays are special types of variables that store more than one piece of related information.
• JavaScript distinguishes between numbers (0-9), strings (text), and Boolean values (true or false).
• Expressions evaluate into a single value.
• xpressions rely on operators to calculate a value.
