Correction marks highlight changes while working on a draft. Lately, strike-through has also become a hip visual style.

To visually record important changes in our text, we can expressively cancel a part of the previous version by marking it strike-through. The opposite action is to mark a part as inserted later.


Strike-through is applied by surrounding text with two swung dashes on every side like ~~deletion~~. There is extra Markdown syntax for an insertion available in Hugo working like ‍++insertion++. This extra extension needs to be enabled in the markup configuration.


See the second paragraph.

Consider that these markings tend to look unprofessional on a finalized page if it’s not some kind of draft or change log.
