Problem
The checkboxes rendered by the Discourse checklist rendering plugin by writing down [] or [x] in the markup are slightly off.

Workaround
/* Fix DMT#15: Checkboxes slightly off */
.contents span.chcklst-box::before {
display: inline-flex;
margin-right: 0.1rem;
margin-bottom: 0.1rem;
}

Thank you in advance for your attention.
