Just to illustrate how easy it is to create a child theme, this is what you would have to do:
- Create a new directory in your site's themes directory. Let's say you call it 'mychild'
- Create a file called 'style.css' in a text editor (like Notepad or gEdit, not a word processor like Word)
Now add the following comments and @import statement (using Notepad or whatever) to your style.css file:
/*
Theme Name: My Child
Template: blaskan
*/
@import url('../blaskan/style.css');
Save your work and then upload the file to your server, putting it into the new directory you created ('mychild').
Now go to your site's Dashboard --> Appearance --> Themes page. You should see the theme 'My Child' listed.
Activate the My Child theme. You may have to redo a few of the configurations you did for your old theme. For instance if you have a custom menu, you will have to go to Dashboard --> Appearance --> Menus and reset your custom menu as the main menu. You might also have to redo any configurations you made in Dashboard --> Appearance --> Header.
So check your configurations and save any changes you make.
You can now visit your site and it should look exactly like it did before. The difference is that you can now make CSS changes in your child theme's css file, leaving the parent theme completely untouched.
