Create a Zen 8.x-7.x sub-theme - Manually.


The Zen base-theme is designed to be easily extended by its sub-themes.

You should Not modify any of the files in the Zen base-theme folder 'zen' at [D8-root]/themes/zen. Instead, create a sub-theme located outside of the 'zen' base-theme folder, placing you subtheme at [D8-root]/themes/my_zen_subtheme_folder_location.

  • "Why subthemes should always be outside of the base-theme."

    Each subtheme should reside in its own folder outside of the base-theme, because that makes it easier to update or upgrade the base-theme in the future.

    If, for example, you were to update the base theme, and if that process deletes the current base theme folder, and if that base-theme folder contained your sub-theme, your subtheme would be lost.

Set Windows to "Show hidden files, folders, or drives", and to NOT "Hide extensions for known file types"

If you are using Windows,
it is important that you
set Windows to display hidden files.
And it is even more important
that you display all file extensions.

By default, Windows hides certain files
that it has classified as worthy of being 'hidden'.
And, by default, Windows does not display
certain file extensions.

I have no doubt that Microsoft did this
to reduce the burden upon
their telephone support department
by reducing the number of calls from,
for example, parents whose 2 to 3-year-olds
play 'drums' on the keyboard.

This is, however,
a completely unacceptable situation
for you as you work on your Drupal site,
and you should adjust Windows
to display all files,
and display all file extensions.
