I can't understand definitely what is replaced elements
I expect to be the elements whose need an attribute to show output on the browser,,i know that there is many replaced elements such as img and video and iframe ,but I cant understand how to identify any replaced element
Replaced elements
"In CSS, a replaced element is an element whose representation is outside the scope of CSS; they're external objects whose representation is independent of the CSS formatting model."
