What is style.css in WordPress?

The style.css is a stylesheet (CSS) file required for every WordPress theme. It controls the presentation (visual design and layout) of the website pages. In order for WordPress to recognize the set of theme template files as a valid theme, the style.css file needs to be located in the root directory of your theme, not a sub-directory.

Here is an example of the header part of style.css –

In addition to CSS style information for your theme, style.css provides details about the Theme in the form of comments. The stylesheet must provide details about the Theme in the form of comments. No two Themes are allowed to have the same details listed in their comment headers, as this will lead to problems in the Theme selection dialog. If you make your own Theme by copying an existing one, make sure you change this information first.
