Dear Spiro,
Source file included for editing the CSS using Sass. Itβs all about the Sass source files. If you know how to use Sass then you will able to edit the Source files to edit CSS using Sass. Otherwise, you could use and edit the included CSS files, there will not be any problem.
Moreover, itβs just a static HTML template. So, it will not work with WordPress directly without converting the template to a WordPress theme. We just show the blogs, search, and pagination for the demonstration purpose of how those will look like to provide a complete design package/concept to match the template if someone wants to make the template to a dynamic website using any programming language.
In this case, you could hire our team or someone else to convert the template to a WordPress theme to dynamic those the blogs, search, pagination, and everything.
Furthermore, please find out the button CSS in the style.css
for both (html template and whmcs template as well) file and replace the color code from there based on your needs and requirements.
