l A class: .class. Class rules apply to all HTML elements with that class. When you
create a class, choose a name that indicates what the class is used for, e.g. ‘small’
for a class that gives elements the font size ‘small’. The class name has to be
preceded by a dot, e.g. .small.
l An ID: #id. An ID is always preceded by #, e.g. #sender. When you create an ID,
choose a name that indicates what the ID is used for, e.g. #sender would refer to the
HTML element with information about the sender.
Note
Each ID should be unique and can only be used once in each section.
l An HTML element: p, h1, table, etc. Type the tag name without the angle brackets.
l A combination of HTML elements, separated by a comma. The CSS rule will apply
to all HTML elements that are listed in the selector. For instance, a CSS rule with
the selector h1, p applies to first level headings as well as paragraphs.
l HTML elements inside other HTML elements. For instance, a rule for all paragraphs
inside a div element has the selector: div p.
l Etcetera. See https://www.w3schools.com/cssref/css_selectors.asp for more CSS
selectors and combinations of CSS selectors.
