Lists without bullets points in Markdown

Like @mb21 specified, here is the CSS if someone needs:

ul {
    list-style-type: none;
    margin-left: 40px;
}

No, with pure markdown this is not possible.

Think of Markdown as a simpler syntax for HTML. To change the styling you'll need to add a CSS to the generated HTML.

This might sound obvious but... you could understand a list as "lines separated by line breaks" (when you think about the output, not the markup).

First item  (<-- two spaces)  
Second item  

This will render to:

First item
Second item

This looks like a list with no bullet points :)
A more beautiful example.
