This is the code for the link block:
{block:Link}
<div class="post link">
<h2>
<a href="{URL}" class="name">{Name}</a></h2>
<div class="content">
{block:Description}{Description}{/block:Description}
<span class="date">
<a href="{Permalink}">{ShortMonth} {DayOfMonth}, {Year}
</a>
</span>
</div>
</div>
{/block:Link}
What I’m trying to do is add a border-left of of 10px to block quotes. When I try to add this style to block quotes this happens:

The block quote border flows into the post title and I don’t wish for this to happen, I want the border layout to stay within the content div.
I’m using this CSS at the moment:
div div div blockquote {
border-left: 10px solid red;
}
Thanks in advance for the help!
Just to clarify <div class="post link"> is in another div.

blockquoteitself and several parents(elements in further text) of it — and not found any negative margins.Then I checked with non-standard values of elements for
displayproperty, but nothing special.Then I searched for specified properties which changing float of layout, and first closely to blockquote element is
div.post.h2which hasfloatsetted toleft.Bingo!
