Nope. HTML compresses any sequence of whitespace characters (spaces, newlines, possibly tabs too if you put them in there) into a single blank space.
To get a line break in html, you need to do one of the following:
Put in a <br> as was already mentioned.
Put the whole thing inside a <pre> </pre> section.
Use a table and start a new row when you want a break.
This is very basic html; perhaps you need an intro text or website?
