Hi Spiros,
If you have the FilterCodes plugin installed on your Moodle site, placing content in a box is very easy. Just surround your content with the plain-text {alert border} tag. For example:
{alert border}This content will be in a box.{/alert}
No HTML or
CSS skills are required.
There are also several background colour styles to choose from which do not have a border. Example: {alert primary}, {alert secondary}, {alert success}, {alert danger}, {alert warning}, {alert info}, {alert light} or {alert dark}. With the border style, as seen above, it will simply put a border around your content.
Note that the {alert border} tag is new and only currently available in the version of FilterCodes on GitHub. See
https://github.com/michael-milette/moodle-filter_filtercodes.
This feature will be included in the next release of FilterCodes. To learn more about FilterCodes, see

Hope you find this information useful.
Best regards,
Michael Milette
