Say I have template structure that I want to implement on every page, like a navigation bar (A series of HTML tags and some CSS that will not change on any page).
Right now, I just had an empty page on my site titled "Template.html" and whenever I have to add a page to my site, I simply copy that page and work off of the template. But is there a way to just throw all this prewritten html in a special type of file and then relate it to a tag, like a CSS stylesheet?
It would be a gamechanger. Just one simple tag that references a file with HTML code and implements it in the page where it is referenced.
