Embedded Style Sheets
The style tags should always located inside the <head> tags before the </head> tag. The format of the style tags is as follows:
<style type="text/css">
</style>
CSS rules would then be inserted between the start style and end style tags.
Understanding CSS Terminology
The basic format of a CSS rule is as follows:
The CSS rule is made up of a selector (the h1), one or more declarations (color: #333) inclosed in a Declaration box (everything inside the curly brackets.) The Declaration is made up of a property (color) and a value (#333).
- Rule - The pairing of a selector and a declaration block
- Declaration block - a set of declarations grouped together and surrounded by curly braces ( { } )
- Selector - Defines the element of the document that will have the declarations applied to them.
- Declaration - A property-value pair that describes how the selector will be formatted or displayed
- Property - An aspect of an element's presentation, such as its color or font-size
- Value - A descriptor defining a specific appearance of a property.
Creating sections of a page
The Div tag can be used to separate a web page into different sections that can be formatted differently.
The attribute can be class or id. Ids must be unique in a document, but you can have several elements with the same class attribute.
The Value is the name of the id or class which can be referred to in a CSS rule statement
Adding styles to a document
Styles within a document should always be defined in the head section of the page, before the </head> tag.
All style rules should be enclosed in the following tags:
<style type="text/css">
</style>
