Build Responsive component

The purpose of this test is to see how well you can code a responsive component using HTML, CSS, and JavaScript. Matching the design is equally important as writing clean, semantic code. -- 2 ## Rules * It's very important to match the design. This component came out of a project and is indicative of the type of work you'll encounter. * JavaScript must be hand coded using Vanilla ES5/ES6+. * Please do not use any JavaScript plugins, frameworks, or libraries (React, jQuery, Lodash, etc.). * Must work bug-free on iOS, Android, Chrome, Safari, Firefox, Edge, and IE11+. * If you choose to use some sort of CLI compilation, include a compiled folder so that the HTML file can be dragged directly into the browser. * Upload a zip file to Dropbox, Google Drive, or any other semi private storage service. Please do not post this on a public repository such as Github. ## Bonus * Write OOP JavaScript. * Add CSS transitions to accordion and tab events. * Create accordion + and - icons with pure CSS. * Use SASS or LESS or any other preprocessor. ## Design Notes * Font used is Open Sans Bold and Regular. * Tablet/Desktop PSD should account for any view larger than 767px. * If you do not have Photoshop, either download a trial version or view the attached `jpgs` for reference.
