First, I recommend you add font-weight:bold to your ul instead of using one big bold tag.

The reason you’re not getting any space below the list is because you need to add some margin. Example:

.double_column_list { margin-bottom:10px;}

I have .double_column_list li {float: left; width: 50%;}

up in my style sheet area

Then I have

<div class="double_column_list">
                  <ul>
                   <b>
                    <li>Computer is running slow</li>
                    <li>Error messages</li>
                    <li>Computer stops responding</li>
                    <li>Blue Screens</li>
                    <li>Your computer doesn't bootup</li>
                    <li>Stop "0x0000000" errors</li>
                    <li>Computer randomly reboots</li>
                    <li>Clicking, whining, or other loud noises</li>
                    <li>Computer will not power on</li>
                    <li>Error messages during bootup</li></b>

                 </ul>
                </div>

when I render the html, it shows that there is no paragraph space between Error Messages during bootup and Sometimes. It is as if I am typing a new sentence and not a paragraph.

I’m sorry, I’m a little unclear on what your problem is. Could it just be a margin issue? Try adding more margin-bottom on the div to push the text below down. It’s hard to help without seeing the code.

I type here but there is no space between this and Error messages during bootup

.double_column_list li {float: left; width: 50%; }

I begin to type here, but there is no line break between these words and the above

Did you add the css to float each list item left and make it only 50% width? You can add html if you enclose it in pre tags.

Like this:

<div>Html here</div>
