Attributes are additional values that adjust their behavior of elements in various ways to meet the criteria the users require.
Some elements do not require attributes like heading tags <h1>, paragraph rag <p> and some others. But most of the HTML tags may have attributes as their characteristics.
An attribute is combination of two things:
Attribute names and attribute values are case-insensitive and should be in lowercase.
The basic elements of an HTML code are:
Heading: denoted using the <h1>, <h2>, <h3>, <h4>, <h5>, <h6> tags.
Paragraph: denoted using the <p> tag.
Horizontal ruler: denoted using the <hr> tag.
Link: denoted using the <a> (anchor) tag.
List: denoted using the <ul> (unordered list), <ol> (ordered list) and <li> (list element) tags.
Image: denoted using the <img> tag
Divider: denoted using the <div> tag
Span: denoted using the <span> tag
