Files structure

Grace Instagram Feed has standard WordPress plugin structure. It includes both PHP files for server-side and JavaScript files to operate on client-side. Main plugin file   FlowFlow.php generates grid HTML and injects JS (like main JS public.js) from /js folder and CSS from /css folder on your site page. Also it’s responsible for plugin options and settings storage.

Source code: PHP and Javascript

Plugin main PHP class is defined in   INSTClassLoader.php. PHP files provide standard WordPress plugin routine like settings and appearance presentation in admin and settings storage in WordPress database and also includes other .php files and injects .js, .css for browser pages. 

Front-end scripting and third-party plugins are located in JS folder.

Design: CSS and images

We use multiple CSS files in this plugin: for admin and public. The first one   admin.css is for plugin styles in WordPress admin like settings page. The second file public.css contains all of the specific stylings for the Flow-Flow on your site pages. Rest are third-party plugin’s CSS for admin e.g. colorpicker

Feel free to edit any of this CSS. Please double-check if editing more than just font or background color.
