Putting two dashes on a page sometimes, like this — in rare occassions messes the HTML up.
For instance, if you enter — into your WordPress blog it’ll actually munch it into a single -. This doesn’t work well for code that requires –options –to –be –specified –this –way.
The HTML entity for – is &ndash and the longer — is — but what is the HTML entity to enter NORMAL DASH – in a page?
This should do it. It’s not listed as a dash, you need to find a place that lists it as the minus sign.
Code block shows code:
In use: - (-)
Double: -- (--)
