HTML Lists, Control Flow with JS, and the CSS Box Model

Chapter 3: Lists (pp.62-73)

• The ordered list is created with the < ol> element.
• Each item in the list is placed between an opening < li>
• The unordered list is created with the < ul> element.
• Each item in the list is placed between an opening < li>
• The definition list is created with the < dl>
• This is used to contain the term being defined< dt>
• use the < dd> to contacin the definition
• You can put a second list inside an < li> element to create a sub- list or nested list.

Chapter 13:Boxes (pp.300-329)

• boxes default size is just enough to hold content
• best way to size bozes is using pixels or px
• you can use min or max height to size boxes to your preset limits
• hidden: This property simply hides any extra content that does not fit in the box.
• scroll: This property adds a scrollbar to the box so that users can scroll to see the missing content.
• Every box has a border (even if it is not visible or is specified to be 0 pixels wide). The border separates the edge of one box from another.
• Margins sit outside the edge of the border. You can set the width of a margin to create a gap between the borders of two adjacent boxes.
• Padding is the space between the border of a box and any content contained within it. Adding padding can increase the readability of its contents.
• If you want to center a box on the page (or center it inside the element that it sits in), you can set the left-margin and right-margin to auto.
• Legibility can be improved by controlling the width of boxes containing text and the leading.

Java Review:

• A Boolean variable can only have avalue of true or fa1se, but this data type is very helpful.
• First, Booleans are used when the value can only be true/ fa1se. You could also think of these values as on/off or 0/1: true is equivalent to on or 1, fa1se is equivalent to off or 0
• Once you have assigned a value to a variable, you can then change what is stored in the variable later in the same script.
• The name of a variable must begin with a letter, dollar sign ($),or an underscore (_). It must not start with a number.
• the name can contain letters, numbers, dollar sign ($), or an underscore (_). Note that you must not use a dash(-) or a period (.) in a variable name
• You cannot use keywords or reserved words. Keywords are special words that tell the interpreter to do something.

• && mean “and”

  mean “or” ! means “not”

• if check a condition if found true it will execute code assigned
• if else executes code set on on conditions outside the previous if
• Back to main
