How to Create a WordPress Theme?

Template files created by WordPress are used for WordPress theme creation. When the theme is created, the theme created in the Appearance>Themes area appears and the theme can be activated and broadcast.

WordPress Theme Development Step by Step

  1. To create a theme on the local computer, the first step is to download the WordPress infrastructure and theme files via the https://wordpress.org/download/ page.
  2. The downloaded file contains theme files under the wp-content>themes directory. To create a new WordPress theme, a folder must be opened here with the theme name. (Like the “wordpresstheme” file created in the example below.)

  3. The theme is created using the theme files of WordPress under the created file. In order for the created theme to appear in Appearance>Themes, the following 2 files must be indexed;
    • index.php
    • style.css

    Without these files, the new theme option does not appear in the theme change area, it gives a warning in this area because there is a missing file.

Software Languages Used in WordPress Theme

WordPress infrastructure is a structure built with PHP, so PHP is used when creating theme files. HTML, CSS and Javascript are used in the design of the theme.

Libraries such as Bootstrap and Jquery are also widely used. Even in WordPress, the Jquery library comes by default. You can use the jquery library or you can choose to use Javascript from the theme for your needs.
