HTML elements are the building blocks of web pages.

The web page below is made up of a collection of HTML elements. Each element is outlined in blue and labeled with its name.

HTML elements describe each piece of content on a web page so that the web browser knows how to display it.

RULE 1: 
Every element that is written in HTML is composed primarily of TAGS, bound by the symbols "<" and ">"
Example: While composing a paragraph element (represented by 'p'), the use of opening tag '<p>' indicates that a paragragh element is being composed

RULE 2:
Every tag in HTML when opened, has to close. The closing tag of the element is defined by the symbol '/'.
Example: If I want to compose a paragraph "My Name is Benedict", I would compose it this way:

                                                    <p> My Name is Benedict </p>

RULE 3:
By now, you may have figured out that the typical element in HTML is defined in the structure as follows:

                                         <opening tag> Text the user can see <closing tag>

RULE 4:
In HTML, we also have certain 'attributes' . It follows the opening tag and has the following structure
                     <opening tag attribute-name="name"> Text the user can see <closing tag>

Example:                                          <h1 id="main"> Portfolio </h1>
