HTML CSS

Attributes

id

HTML

Specific style for a single element. Note: The id of an element should be unique within a page, so the id selector is used to select one unique element!

CSS

1. idTag {

   color: blue;

}

class ATTRIBUTE ---

HTML

To define a style for a set of elements, add a class attribute to the element

CSS p.classTag {

   color: red;

}

A block-level element always starts on a new line and takes up the full width available (stretches out to the left and right as far as it can).
