"indent by four spaces" ← what does this mean? I'm going to ask a question on http://stackoverflow.com/ . And I need to post my Java code there. However, as I'm going to post my code, I find problems with the following sentences: To create code blocks or other preformatted text, indent by four spaces: This will be displayed in a monospaced font. The first four spaces will be stripped off, but all other whitespace will be preserved. Markdown and HTML are turned off in code blocks: This is not italic, and [this is not a link](http://example.com) To create not a block, but an inline code span, use backticks: Press the `<Tab>` key, then type a `$`. If you want to have a preformatted block within a list, indent by eight spaces: 1. This is normal text. 2. So is this, but now follows a code block: Skip a line and indent eight spaces. That's four spaces for the list and four to trigger the code block. What I don't know is this sentence "indent by four spaces". Does it mean type four consecutive spaces? I've tried to type four consecutive spaces, but I failed to create a code block. Does anybody know how to create code block on that website?
