Customise some sections in a wordpress website to add the requierd features. -- 2

We need to add the following features to our website: 1. Text animation. We need a further customisation on a Wordpress plugin that we are using to add animated text to a different sections of the website. The current plugin can only animate one keyword/phrase. We need it to be able to add a list of keywords/phrases. Also we need to fix a bug in the plugin. The bug is causing the shortcode functionality in the theme to be disabled and not functioning when the plugin activated. The plugin name is 'Easy Textillate’. Kindly note that we are not the owners or the developers of this plugin. 2. Adding a light box to a section in the website. We need to add this technique to a list of keywords, upon the click of a keyword, an additional content revealed within a full-screen lightbox. The additional content includes headlines, paragraphs and button. Note: a. We are using an advanced Wordpress theme that use visual composer and shortcode to add/design the website. We require any customisation to be done using these capabilities and not by editing the native theme CSS style or coding. b. Any customisation on the Wordpress should be maintained and carried over when a new updates released on the CMS or the theme itself.
