I need to do some UI development (HTML, CSS mainly) using some UI Kits. To save my time and remain DRY i want to use some simple template inheritance tool so that I can include and extends header, footer, nav etc.

I am searching for it but couldn't found anything standard, for time being, I am using nunjucks with gulp.

What do you use in this situation ? Any tool that you would like to recommend so that I can start easily with minimum stuffs.

Note: I am not using express/node or react/vue etc.
