So everyone gets rid of the icons and colors of the old sample, I slightly changed the design of the template by analogy with the template from the Russian Wikipedia. Which changes:
- Cleaner HTML. Separate blocks and classes for header, content and footer blocks.
- All styles are transferred to CSS - Module:Documentation/sandbox/styles.css.
- Color changed from green to common blue.
- Footer is no longer built on {{fmbox}}.
- Added some fixes from English Wikipedia.
- Replaced documentation icon for icon from OOUI set.
- Replaced sandbox icon for more cleaner.
- Add translation table Module:Documentation/sandbox/i18n
Please, check it here - Template:Documentation/sandbox :)
