Idea to add a search bar on the main site header template

[jwmeyert7]

It seems it would be useful to have a search bar somewhere along the website header template that searches through any pages on the main site and also the knowledge base. I think a lot of people come to ethstaker.cc looking for help and the search bar would be used in this way.

Creating this as an issue because it's an idea but I'm not at the point where I'd put a pull request together about it.
