We download and use ready made theme from drupal. However, if you want to look more professional or you don't want people knowing which theme you are using from the source code.
When you make a new theme, modify the "theme names" in the following files. I used theme "acquia_marina" as an example:
- acquia_marina.info
- style.css
- layout.css
- template.php
Basically, whenever you find the text "acquia_marina", replace it to "your_prefer_theme_name"
style css
