Main Stylesheet (style.css)
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 subdirectory.
For more detailed explanation on how to include the style.css file in a theme, see the “Stylesheets” section of Enqueuing Scripts and Styles.
WordPress uses the header comment section of a style.css to display information about the theme in the Appearance (Themes) dashboard panel.
Here is an example of the header part of style.css.
/* Theme Name: Twenty Twenty Theme URI: https://wordpress.org/themes/twentytwenty/ Author: the WordPress team Author URI: https://wordpress.org/ Description: Our default theme for 2020 is designed to take full advantage of the flexibility of the block editor. Organizations and businesses have the ability to create dynamic landing pages with endless layouts using the group and column blocks. The centered content column and fine-tuned typography also makes it perfect for traditional blogs. Complete editor styles give you a good idea of what your content will look like, even before you publish. You can give your site a personal touch by changing the background colors and the accent color in the Customizer. The colors of all elements on your site are automatically calculated based on the colors you pick, ensuring a high, accessible color contrast for your visitors.
