Whats the difference between inline element and inline frame?

Question

i am really confused. are the elements different from a content? are contents elements? what's it?

Answer 1

In html an inline element show content in a continuous way without a new line
Example:
<p>This is a <span>nice</span> paragraph</p>
span is a inline element

An inline frame <iframe> is for embed a web page inside other web page
