Steps Through Drupal 7 Theme Development
There are various ways to start the theme development, either by sketching the layout of home page of your site, design the site using CSS & HTML, establish Drupal to begin theming or understand the web page structure of Drupal and then, convert your static pages to it.
2. Building Theme Files
The steps, involved in creating theme files are the setting up the theme folder them, then building template files and inserting the process & pre-process functions.
A .info file is created, containing the theme’s purpose along with the information about how it can be used. Now, you need to add a CSS folder and screen-shots into it. Drupal template files are generally used to structure the output of web page. Template files are the files that have a name ending in .php, .tpl, etc., means “PHP template”. In order to understand process functions, you need to have knowledge about how Drupal saves & outputs the data and HTML markup. Basically, these functions allow you to modify the variables available to the templates ,before Drupal CMS makes them ready for use by the templates.
Now, you can install the Drupal theme, establish the required views as well as add the required regions and nodes. Once the theme is installed, you need to install the additional modules to enhance your site’s appearance, security and functionality. Then, add the website content in order to complete your site.
