If you add a link of a jsFiddle without adding code to a reply, it gives you a prompt to also add code. This code is either a complete block of code or inline code. But in the case of a question, a proper block of code is required to understand the situation. As in this question, it contains a jsFiddle link, but the inline code is completely irrelevant to the original issue.
So prompting complete code in case of inline code for a question will be quite helpful for the solving issue and for future visitors as well.
