Create a child theme for thematic with easy steps

         Spending money for buying a theme for Wordpress or Blogger is not always necessary. We can create a beautiful theme at free of cost easily. All you need is only some hours even if you are not geek.
        Creating a child theme for twenty ten is easy. I wrote an article about that previously.

Now, We can create a child theme for thematic.
        Thematic is a framework for Wordpress like Twentyten, Genesis etc. Also some of the features includes:

• Perfect to use as-is or as a blank WordPress theme for development
• Fully Search-Engine Optimized
• Extra widget-ready areas (13 in total) and more possible in your Child Theme
• Free and commercially supported Child Themes are available for upgrading the theme
• Includes a sample WordPress Child Theme for rapid development
• A wiki-editable guide to Thematic Customization
• Ready for WordPress plugins like Subscribe to Comments, WP-PageNavi, and Comment-license
• Fully compatible with All-In-One SEO and Platinum SEO plugins
• Multiple, easy to implement, bulletproof layout options for 2, or 3 column designs
• Modular CSS with pre-packaged resets and basic typography
• Dynamic post and body classes make it a hyper-canvas for CSS artists
• Editable footer text—remove the theme credit without harming the theme
• Options for multi-author blogs

Now, we can create a child theme

1. First, Download thematic from here
2. After you unzipped the Thematic zip file
3. Find the "thematicsamplechildtheme" sub folder.
4. Rename the folder as you like. eg. bluechild
5. Open the style.css file, and edit these area with your details

1. /*

   Theme URI:

1. 
   /* Reset browser defaults */
   @import url('../thematic/library/styles/reset.css');
   
   /* Apply basic typography styles */
   @import url('../thematic/library/styles/typography.css');

   /* Apply basic image styles */
   @import url('../thematic/library/styles/images.css');
   
   /* Apply default theme styles and colors */
   /* It's better to actually copy over default.css into this file (or link to a copy in your child theme) if you're going to do anything outrageous */
   @import url('../thematic/library/styles/default.css');
   
   /* Prepare theme for plugins */
