Showing a less than symbol in a Blogger post

This took me ages to sort out so here is a reminder. If you want to post a less-than symbol in a Blogger entry (for example in some code or a math formula), you cannot use the standard HTML entity “<” as Blogger cannot cope with it for some reason. Instead use the hexadecimal equivalent “& # 60 ;” (NB: I’ve put spaces in so that Blogger doesn’t turn it back into a symbol!). That works fine and shows the symbol (< ) as expected.   Also note that normally you can just enter a <> blocks or where there is no space after it. Not Linux related I know 😉
