[#LightningStrikes] The best tip for lightning developers that I would give is to use the Lighting Components (https://developer.salesforce.com/docs/component-library/) instead of plain HTML controls to make the best out of Lightning. It has all features of lightning within itself, not needed to customize your HTML controls. Also, to style your components, make use of SLDS framework than embedding other third-party frameworks as SLDS has robust features that is auto-fit for all lightning pages. With these, your custom lightning component appears standard!
