Basic HTML Concepts

A webpage is made up of three components: text content, references to other files and markup. HTML markup is composed of elements, attributes and values. Semantic HTML means that content is marked up with HTML elements that best describe it without regard for how the content should look. HTML doesn’t control how your pages look, CSS does. Note that every web browser has a built-in CSS file that dictates how each HTML element should be displayed by default. When you write your CSS it overrides these settings.

Attributes

Attributes provide additional information about HTML elements. HTML elements can have attributes. Attributes are always specified in the start tag. Attributes come in name/value pairs like: name=”value”.
