How to add custom HTML to node content? I'm new to Drupal coming from Wordpress, but I was able to put a site up&amp;running. Theming is easy in WP, but I have not figured that out in D7.

I have a Content Type and the node-content output HTML as below. But I wanted to add custom html in-between section of the node-content:

&lt;div class="node-content"&gt;
    &lt;div class="section field field-name-field-xxx "&gt;
    ....
    &lt;/div&gt;
    &lt;!--need to add My Custom HTML here--&gt;
    &lt;div class="section field field-name-field-yyy "&gt;
    ....
    &lt;/div&gt;
&lt;/div&gt;


I have searched online but I am not getting the basic instructions how to proceed. Presently I'm using a child theme of Zircon.

Any help?
Create a custom template file node--type.tpl.php where type is the machine name of your content type. 

Place it in your theme's templates folder /sites/all/themes/YOURTHEME/templates and clear/flush the cache to see changes.

Ex: Article content type: node--article.tpl.php

&lt;?php print render($content['field_xxx']); ?&gt;

// custom html goes here

&lt;?php print render($content['field_yyy']); ?&gt;
