Hello Andre
You will get a wonderful 'surprise' then in Template Tools 3 
Examining the anatomy of a Joomla! Template
When someone sets off to buy a car, one of the deciding factors is certainly the look of it. However, as every 'petrolhead' could attest, that isn't the ultimate factor. He'd eventually take a look under the bonnet and make sure that what he found was to his liking. What does this have to do with templates? Templates are not dissimilar to cars. A template is, in fact, your site's entire presentation layer–bodywork, chassis and engine included. If you really want to make sure you're choosing the right template for your site, you certainly have to look deeper than its looks.
Where and what are the template files?
Before we even begin taking our look, we need to know where to look. When you install a template in Joomla!, it puts its files in a subdirectory of the template directory in your site's root. For example, the JAPurity stock template is in templates/ja_purity. Inside that directory you'll see an assortment of files and directories. Each template is structured differently from the next, but we'll let you know what are the common parts you should expect to find.
The file index.php is the heart and soul of your template. It is the only file Joomla! will automatically load when it is asking your template to render (display) a page of your site. Since it is executable code it should contain a line similar to:
defined( '_JEXEC' ) or die( 'Restricted access' )
In fact, all of the PHP files in the template – unless they are supposed to be called directly from the web – must have this line. If they don't, your template is potentially vulnerable to a number of attacks commonly used by hackers, so it's a good idea not to use it.
Some templates have two more important PHP files. One of them is a file called offline.php, used to display the notification page when you put your site off-line in Global Configuration. If this file is not present, as is usually the case, Joomla! will load its standard templates/system/offline.php file which is just a bit too generic if you don't want to look like an amateur.
The other important file commonly not in a template is the error.php file, used to display error pages, such as 404 ('not found') page, or the infamous 500 ('system error') page. Again, if Joomla! can't find this file in your template, it will default to the generic templates/system/error.php file.
You can test the off-line looks without taking your site off-line. Just append ?tmpl=offline to your site's URL, eg http://magazine.joomla.org/?tmpl=offline. The same goes for the error page. Just append ?tmpl=error to the URL, eg http://www.joomla.org/index.php?tmpl=error.
Another small file that can be forgotten by template developers and web masters is the 'favicon'—a 16x16 pixel file named favicon.ico containing the small icon you see next to the site's URL in the address bar. If your template doesn't have one, most browsers will display a blank page icon, which looks extremely unpolished. If your template does have this file, please remember to change it from the default Joomla! favicon.
Template Overrides
One of the most important features of Joomla! templates is the ability for a template to override the output of a component. There are two reasons you might want to do that. Right now, Joomla!'s core output uses old table layouts. Most better templates override those old layouts with more modern, accessible div based output. The second reason you may wish to override the output is to build a very unique layout that you cannot achieve only with CSS. If you want to see how that can be accomplished, you can look at the core JAPurity template's html directory or learn from the Beez stock template. In selecting templates today, look for these overrides. Later, when 1.6 is released, the core output will be much more accessible, and then overrides will only be used for special design purposes.
Historically, when Joomla! 1.5 was in development, no template developer was familiar with overrides and nobody knew how to use them. When Beez came out, overriding every single view in every single component and virtually every usable front-end module, it became the template of templates as far as overrides are concerned. The vast majority of overrides appearing in templates are based on the original work made in the Beez template. We owe its creators, Angie Radke and Robert Deutz, a huge 'thank you'!
In the html directory in your template, you willl see numerous directories. For example the com_content directory contains the template overrides for Joomla!'s com_content component, whereas the mod_latestnews directory contains the overrides for Joomla!'s 'Latest News' module and so on. Many templates also provide overrides for third party components, such as K2, JomSocial, Tienda etc. This is very common and doesn't require the third party component to be installed at all for the template to work. So don't worry if you see, for example, a com_k2 directory in there. You template supports K2 but it doesn't require K2.
Each extension subdirectory in the template's html directory has a few directories of its own. Each directory is one specific 'view' of that particular component. Each view folder may have one or several PHP files. These files contain the actual overrides. These are also called templates or views. Since these files override the original template files of the component, you've got the etymology of our term, 'template overrides'.
Cascading Style Sheets
There are certain CSS files that should exist in the template's 'css' directory. The first file is named template.css and considered to be the base CSS file of your template. It must exist as other extensions expect it to be there.
An often missing, yet very useful, file is editor.css. This file defines the stylesheet to be used by Joomla!'s content editor, which is by default TinyMCE, to display the content you're editing. It is extremely important because without it there is no visual correlation of what you see in the editor and what you get on your site which defies the whole point of having a WYSIWYG editor in the first place. Unfortunately this often doesn't exist but you can compile a new css file named editor.css and include the styles (eg typography) from the other style sheets available in your template folder/directory.
Most web developers feel that it's best to have the 'typography' styles in a separate CSS file. Typography includes not only the styles for the display of the standard html elements but also can include special styles for your content. For example, in many templates you can add a 'notice' class to some text to make it look like a warning message with a yellow background and a warning icon. There are a few reasons why this is a good idea. One reason is that separating out your typography into one location makes it easier to change the font or to adjust the ems (or pixels) of your headings later. If you have these values in multiple locations, it is very difficult to achieve a consistent look. Also, it is important to 'protect' users who are not technical from changing 'layout' or 'position' values that would negatively impact their display sitewide.
Inline CSS
These are those style='something' attributes in HTML elements inside a template file. A professionally crafted template will never have something like that in its PHP files! If you see anything like it, it probably means that the developer decided to take a shortcut to a layout issue instead of fixing it properly. The cascade of a style sheet loosely means that the style closest to the html it is controlling is the most imortant (specific) and therefore applies despite what is in a css file elsewhere in the template. They can't generally be overriden in CSS files. They are the most specific level of CSS styles, therefore they will always override styles defined elsewhere. This makes customisation of the template just plain impossible.
Images
Another thing easily spotted is the use of image tags (img) instead of CSS background images. It's fine to see one of them used in a logo position, but this is not good practice in modern webdesign.
Tables
Since the advent of CSS 2.1 in the early 00s when it became supported by all mainstream browsers using tables for positioning the content on a web page has mostly, and should have, been discontinued. There is nothing wrong with using tables to display data - that is what they are designed for but do choose a CSS based template for your Joomla! site.
Hidden Links
One huge warning now. If you ever see a template with hidden links, don't ever consider using it. Hidden links are the fastest way to be blacklisted by search engines or having your site at the very end of search results-this is a spammer's tactic. That said, it's easy to spot hidden links. Look for URLs in HTML comments or for text made invisible with CSS: display: none; link elements floated off-screen (eg margin-left: -1000px;) or the all-time classic white text on white background. All you have to do is install the template on a test site and view the page source in your browser. If there's a URL in that page source text which isn't visible on your page, uninstall the template. Period. Please do, however, respect the credit/copyright statements in the code of your template.
Suggestion
Finally, this is more of a suggestion to template developers than a precondition for a good template. We like a dedicated logo module position! Most templates come with instructions about replacing an image file here, editing a file there if you want (you do want!) to change the site's template. This is so 'not Joomla!'. Joomla! is supposed to be fully customisable from the web browser. Ideally, you could just create a Custom HTML module, publish it in the logo module position and the site logo would be easily changed. Thankfully, some template authors do already have this feature and even the ability to change the logo in template administration. So, even though not having this module position is not an ultimately bad thing for a template, including it should certainly earn it some prestige points – not to mention make it easier to use!
Ultimately, you get to decide the make and model of your template. It is your duty to make sure that it looks as pretty under the bonnet as it looks fabulous from the outside. If it's the first time you are doing this, don't feel too confused. Take it easy. Thousands of people before you have been in your shoes when choosing their first car... um... template.
