Chapter 10: Introducing CSS Summary

• CSS treats each HTML element as if it appears inside it’s own box and uses rules to indicate how that element should look.

• Rules are made up of selectors (that specify the elements the rule applies to) and declarations (that indicate what these elements should look like).

• Different types of selectors allow you to target your rules at different elements.

• Delarations are made up of 2 parts: the properties of the element that you want to change, and the values of those properties.

• CSS rules usually appear in a separate document but they may appear within an HTML page.

• Used in an html document to tell the browser where to find the css file used to style the page.

• href Used to specify the path to the CSS file.

• type Used to specify the type of document being linked to.

• rel Used to specofy the relationship between the HTML page and the file it is linked to.

• Universal Selector: * Applies to all elements in the document.

• Type Selector: Matches element names

• Class Selector: . Matches an element whose class attribute has a value that matches the one specified after the period.

• ID Selector: # Matches an element whose id attribute has a value that matches the one specified after the pound or hash symbol.

• Child Selector: Matches an element that is a direct child of another.

• Descendant Selector: Matches an element that is a descendant of another specified element.

• Adjacent Sibling Selector: Matches an element that is the next sibling of another.

• General Sibling: Matches an element that is a sibling of another.

Chapter 2: Basic JavaScript Instructions

• 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. Expressions rely on operators to calculate a value.

Chapter 4: Decisions and Loops

• Conditional statements allow your code to make decisions about what to do next.

• Comparison operators are used to compare 2 operands.

• Logical operators allow you to combine more than one set of comparison operators.

• If…else staements allow you to runone set of code if a condition is true, and another if it is false.

• Switch statements allow you to compare a value against possible outcomes.
