I need help with code in discussions.

I do prefer you use this link as reference: http://daringfireball.net/projects/markdown/basics

Ex: <div>Hello World</div>

<div>Hello World</div>

Let me see:

 <blockquote>
 <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
  </blockquote>

Try adding 4 spaces before the div

<div>Hello World</div>

The pre tag doesn't work (it's ignored) so just add 4 spaces (or more) at the beginning of every line of code

            <p>Hi</p>

<p>hello world</p>

weird, it does work for me

     <p>yes it does</p>

the spaces go at the beginning of your line of code; not before your code (just in case)

Yes i understood that but still it doesn't work,

    <p>no it doesn't</p>

<p> i'm wondering if it still works </p>

I find it easiest to do anything that isn't a single word or two in a code block. To make a code block, you need a blank line between the last bit of text and the start of your block. Your block starts and stops with three backticks. A backtick looks like ` and, on US keyboards, is the unshifted version of the ~ and is usually up near the ESC key.

``` this is a code block ```

becomes

this is a code block

You can also syntax highlight the code by putting the language name after the first trio of backticks, like ```javascript.

If you want to use code in a sentence, just a single backtick ` on either side of the bit of code. `Like this` becomes Like this.
