Why does CSS not support negative padding?
...
Eh, it's a reason, but I wouldn't call it a satisfactory one. This is a case where the spec goes beyond telling me how to define my page and starts telling me how I should define my page. If I want my content to overlap my background edges, borders and/or margins, that should be ...

Why are there two kinds of functions in Elixir?
...
Just to clarify the naming, they are both functions. One is a named function and the other is an anonymous one. But you are right, they work somewhat differently and I am going to illustrate why they work like that.

...tains well-formed (i.e., syntactically correct), but
semantically erroneous, XML instructions.
They state that malformed xml is an example of bad syntax (calling for a 400). A malformed query string seems analogous to this, so 400 doesn't seem appropriate for a well-formed query-string which...
