today I played around a little bit with Tumblr. I tried to add a preformatted text into a description paragraph block like so:
{block:Description}
<p id="description">{Description}</p>
{/block:Description}
However, the <pre> element gets rendered just after the <p> element and not within it which was my intention.
Am I doing something wrong here or is it a bug?
You cannot nest block-level elements, such as <pre>, inside <p> in HTML. So Tumblr is behaving correctly.
You should close your paragraph before inserting the pre-formatted text.
If you want teletype-style text, try the <tt> tag, but note it is a non-standard element and may not render in all browsers. The correct way to achieve formatting is using CSS.
Also, I just realized where I was having a similar issue pasting code into tumblr inside <pre> and <code> tags is that just because you wrap your code in those tags doesn't prevent you from having to escape the carrots with < and > instead of the carrots.
