HTML consists of a series of elements, which you use to enclose, or wrap, different parts of the content to make it appear a certain way. The main parts of our element are as follows:
This consists of the name of the element (in this case, p), wrapped in opening and closing angle brackets. This states where the element begins or starts to take effect — in this case where the paragraph begins.
This is the same as the opening tag, except that it includes a forward slash before the element name. This states where the element ends — in this case where the paragraph ends. Failing to add a closing tag is one of the standard beginner errors and can lead to strange results.
This is the content of the element, which in this case, is just text.
An attribute should always have the following:
A space between it and the element name (or the previous attribute, if the element already has one or more attributes).
The attribute name followed by an equal sign.
The attribute value wrapped by opening and closing quotation marks.
in html semantics means the meaning or effect of the tags the attributes (even if they have the same effect ) they have no semantic meaning.
Search engines will consider its contents as important keywords to influence the page’s search rankings (see SEO)
