Theme development

I want to display Field "field_summary" and "field_tags" of a node in html.html.twig (without using a module for that) as metatags. I was already able to get "field_summary" value in html.html.twig with this code:

Hello,

I have the MAYO theme installed am using a subMayo creation. According to the MAYO Theme write-up, it does everything that I want it to do. The problem I have is HOW? Is there an interface that I'm missing somewhere? Do I need to make all of my changes in the .css files? Is there a documentation file somewhere that actually has some information?

At this point, I just want to change the header image (keeping the logo.png image intact) and create a site-wide background image.

Any assistance would be greatly appreciated,

After creating .theme file in my template folder (whether empty or not), I get the following error message:

I am trying to check the field for completeness and if there is a loaded video in the field, display a small icon on the preview layer. doing so:

<?php if(!empty($fields['field_video'])) echo '<div class="ribbon-wrapper-gold"><div class="ribbon-gold">with video</div></div>'; ?> 

But with video always appears regardless of whether the field_video field is filled or not. What am I doing wrong?
