Html lists:

• There are three types of HTML lists: ordered, unordered, and definition.

• Ordered lists use numbers.( ol tag)

• Unordered lists use bullets.(ul tag)

• Definition lists are used to define terminology.(d1 dt dd tags)

• Lists can be nested inside one another.( li tag)

boxes:

• CSS treats each HTML element as if it has its own box.

• You can use CSS to control the dimensions of a box.

• You can also control the borders, margin and padding for each box with CSS.

• It is possible to hide elements using the display and visibility properties.

• Block-level boxes can be made into inline boxes, and inline boxes made into block-level boxes.

• Legibility can be improved by controlling the width of boxes containing text and the leading.

• CSS3 has introduced the ability to create image borders and rounded borders.

ARRAYS:

An array is a special type of variable. It doesn’t just store one value; it stores a list of values.

• You should consider using an array whenever you are working with a list or a set of values that are related to each other.

• Arrays are especially helpful when you do not know how many items a list will contain because, when you create the array, you do not need to specify how many values it will hold

CREATING AN ARRAY:

• You create an array and give it a name just like you would any other variable (using the var keyword followed by the name of the array).

switch statemant&loops:

• switch statements allow you to compare a value against possible outcomes (and also provides a default option if none match).

• Data types can be coerced from one type to another.

• All values evaluate to either truthy or falsy.

• There are three types of loop: for, while, and do … while. Each repeats a set of statements.
