Video Tutorial Theme creation

We will now get to the heart of the matter and create the first files of our theme.

The necessary files

To create a WordPress theme you must create a new folder in the folder wp-content / themes and place a first php file named index.php. This file will be automatically used to generate the pages of your theme. You will also need to create a file style.css which will contain the style of our theme but especially a comment that will allow WordPress to know the information of your themes.

The only information required is the name of the theme.

Theme Name: My theme

But it is possible to insert more information if you wish. For example here is the code present in the TwentyTwenty theme.

/ *
Theme Name: Twenty Twenty
Text Domain: twentytwenty
Version: 1.1
Requires at least: 4.7
Requires PHP: 5.2.4
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.
