How can I have two header templates with fancyhdr, according to the model of the image.

The code below causes problem, as you show the images.

documentclass[12pt,a4paper]{article}



usepackage{lipsum}% only for dummy text

usepackage{showframe}% don't use in real document

renewcommand*ShowFrameColor{color{red}}% don't use in real document



usepackage{fancyhdr}

usepackage[left=3cm, right=3cm, top=2cm, bottom=2.0cm]{geometry}

usepackage{multicol}

usepackage[most]{tcolorbox}

usepackage{tikz}

usetikzlibrary{shadings}

usepackage{lineno}



 definecolor{AbstractColor}{RGB}{238,243,235}

 definecolor{EBC-Green}{RGB}{43,107,0}

 definecolor{textnumberbox}{RGB}{192,210,177}

 definecolor{EBC-Grey}{RGB}{123, 121, 121}

 definecolor{green_colour}{RGB}{191,201,176}
