How can I modify Joomla article styles?

Question

I'm using Joomla 2.5.8 for my website. Now I want to style the articles of my Blog. Under the article div I want to add another div with an image to have a special effect. Is this possible?

This is the HTML from Joomla:

<div class="item column-1">
    <h2>Test 2</h2>
    <ul class="actions"></ul>
    <dl class="article-info"></dl>
    <p>Das ist der zweite Test-Beitrag!</p>
    <div class="item-separator"></div>
</div>
<div class="item column-2">
    <h2>Test</h2>
    <ul class="actions"></ul>
    <dl class="article-info"></dl>
    <p>Das sind die Blog-Einträge</p>
    <div class="item-separator"></div>
</div>

And that's it how I imagine it:

<div class="item column-1">
    <h2>Test 2</h2>
    <ul class="actions"></ul>
    <dl class="article-info"></dl>
    <p>Das ist der zweite Test-Beitrag!</p>
    <div class="item-separator"></div>
</div>

<div class="myDiv"></div>

<div class="item column-2">
    <h2>Test</h2>
    <ul class="actions"></ul>
    <dl class="article-info"></dl>
    <p>Das sind die Blog-Einträge</p>
    <div class="item-separator"></div>
</div>

<div class="myDiv"></div>

Can you help me, please?

Please avoid customizing the core Joomla files. Yes, you can customize like that by using the template overridden method. For more details go the link below:
