I am implement an external application that should be embedded into the Visualforce page. The application is based on the HTML and CSS. For the front-end I've choosen a bootstrap.
Additionally my application should be 'Lightning Ready'. That means that all elements on the page and general look and feel of the app should match the style guide of the lightning design.
What is the best practice integrating SLDS into the application? Is jQuery a right choice for that? Or should I just adapt existing bootstrap css classes for the new design?
