Body

Thanks Jint,
But It looks that I can see only the stylesheet (style.css) how can I see the body of all the pages of my site? I need to put the code of expo-Max.
<script type=”text/javascript”>
document.write(unescape(‘%3Cscript type=”text/javascript” src=”‘+document.location.protocol+’//expo-max.com/adserver/js/”%3E%3C/script%3E’));
</script>
<script type=”text/javascript”>
expomax_track(‘6bG7LcM7FkUpQRw1FCgTKA%3d%3d’);
</script>
<noscript><img src=”https://expo-max.com/analytics/track/6bG7LcM7FkUpQRw1FCgTKA%3d%3d.gif&#8221; alt=”Website Traffic”></noscript>

where I paste it? Can I do in the page editor where I can select and edit every page? Thanks again for any help.
