    HTML Tag Component

    An HTML tag has two major components:

    • Tag name
    • Attributes

    Tag Name: The word or character written in HTML just after the < symbol is considered as a tag name. Attribute: The word or character written in an HTML tag just after the tag name is considered as a tag attribute. A tag can have many attributes. Attributes provide additional information about the tag. Example:

    <a href =””> Google </a>

    In the above example, a is the tag name and href is an attribute and Google is the content of <a> tag.

    Tags that have an opening and ending tag are known as pair tags. Examples: <p> for paragraph </p>, <h1>for heading </h1>.

    • Single tags

    Tags that do not have opening and ending tags are known as single tags. Examples: <br/>, <hr/>
