Style blogs

[robinglen]

We now have gullwing blogs:
https://www.gullwing.io/blog/beyond-gitops_how-we-release-our-microservices-on-kubernetes-at-ynap.html

But they don't match the homepage style, what makes this style? The CSS which you can see is currently inline:
https://github.com/gullwing-io/gullwing-io.github.io/blob/main/index.html

We want to apply this style and HTML elements to the script that generates the blogs. We also want to include the google analytics tags and other things like mega tags, title description, og:images etc

This will need to be sharable for all blogs generated but also have dynamic elements as each blog is slightly different.
